Allowing for Expansion and Contraction.
Vinyl siding contracts and expands as the outside temperature changes. To avoid structural or aesthetic problems associated with this characteristic, take the following steps:
For more information, refer to page 15 of the VSI Vinyl Siding Installation Manual.
Your main goal in preparing the walls of the structure is to ensure a flat, even surface. On any project, remember to install code-compliant flashing before starting to apply siding.
As stated in the VSI Vinyl Siding Installation Manual, before you begin construction on a residing project:
As stated in the VSI Vinyl Siding Installation Manual, before you begin installing vinyl siding in a new construction project:
For more information, refer to page 17 of the VSI Vinyl Siding Installation Manual.
Choose aluminum, galvanized steel, or other corrosion-resistant nails, staples, or screws. Aluminum trim pieces require aluminum or stainless steel fasteners. Remember, as temperatures change, vinyl siding can expand and contract ½" (12.7mm) or more over a 12'6" (3.81m) length. Nails:
No matter what fastener you choose, follow the basic fastening steps listed below:
For more information, refer to pages 14 and 15 of the VSI Vinyl Siding Installation Manual.
You can use a circular saw, tin snips, utility knife, or a scoring tool to cut vinyl siding. Depending on the tools you use, for a safe, clean, and straight cut:
For more information, refer to page 16 of the VSI Vinyl Siding Installation Manual.
As stated in the VSI Vinyl Siding Installation Manual, always install flashing that meets the requirements of ICC AC148, such as aluminum coil stock, around windows, doors, other openings, inside and outside corners, and the intersection of walls and roofing. The most important tip to remember when applying window flashing is that flashing should extend past the nail flanges of the window (or any accessory) to prevent water infiltration. The flashing must be long enough to direct water over the nail flange of the last full course of siding.
With this in mind, you should first apply the flashing on the underside of the window, then to the sides of the window (make sure to overlap the bottom flashing), and finally, to the top of the window.
For more information, refer to page 20 of the VSI Vinyl Siding Installation Manual.
For the most part, follow the same procedures for installing vertical vinyl siding as horizontal siding, with a few noted differences. Below, you'll find a summary of important steps that apply only to vertical panel installation:
Getting Started with Vertical Siding
Installing Vertical Siding Panels:
Working from the starter strip to the corners, lock each panel and fasten every 12" (305mm). Vertical panels are terminated into the J-channel installed at top and the vertical base or J-channel installed at bottom.
Windows and Doors:
For more information, refer to pages 27 - 31 of the VSI Vinyl Siding Installation Manual.
Ventilation is an important aspect of soffit installation that should be considered before you begin work. Consult a local building official for the appropriate requirements for your area and use vented soffit or other vented products as necessary.
Inspect and plan your job in advance. Surfaces should be uniform and straight from any viewing angle. For residing applications, nail down any loose panels, boards, or shingles and fur when necessary.
Installing Soffit Over Open Eaves
For more information, refer to pages 32 - 35 of the VSI Vinyl Siding Installation Manual.
To remove a panel for any reason, follow the steps below:
For more information, refer to page 37 of the VSI Vinyl Siding Installation Manual.
There are several distinct differences that are worthy of consideration as follows: maintenance, cost, and beauty/color. Hardie siding is a more expensive choice for the initial installation (approx 35%) and maintenance costs over the life of the product. Below are comparisons to help the decision process.
Vinyl Siding Hardiplank (Fiber cement board)
MAINTENANCERequires no maintenance except periodic rinsing with a garden hose or pressure washer. Requires the homeowner to maintain (eg: paint) the siding on a periodic basis. FCS will hold paint for a longer period than traditional wood or composite sidings.
COSTCan be applied over the old siding after any areas that are rotted or in poor condition are repaired. Very little waste disposal costs. Old siding must be completely removed and disposed of prior to applying new siding. There is a considerable amount of material to dispose of.
With the introduction of high grade durable vinyl products, it would be a huge mistake to compare the beauty to low grade apartment communities or cheap builders grade siding jobs. A high quality job will be pleasing for many years. However, the color cannot be changed since vinyl siding cannot be painted. Hardie siding will be aesthetically pleasing for many years. It has a nice wood grain texture and the siding color can be changed if so desired.
In a way, it's almost no contest. When compared to wood, brick, stone, stucco, and metal sidings on the basis of initial cost, maintenance costs, appearance, durability and value, vinyl siding is clearly superior.
We offer a broad range of vinyl siding products, so you can choose one that's easily affordable. Whichever you choose, you can expect the highest quality and lasting beauty. And most vinyl siding never needs painting or staining. It doesn't chip, peel, dent or rot, so you can forget costly repairs. Just rinse occasionally with a garden hose.
In addition, vinyl sidings are backed by a strong warranty. And because vinyl is the preferred siding for more and more homeowners, it retains most of its installed cost. Moreover, premium vinyl siding provides all the beauty of expensive wood sidings with your choice of smooth or grained surfaces; rich, low-gloss colors; and a variety of classic siding profiles.
If you plan to move within the next three years, the answer is probably "yes." But if you plan to stay in your home longer than that, the calculations begin to heavily favor vinyl siding.
Of course, if your home has special problems - for example, warped clapboards that have to be replaced or lead-based paint that has to be scraped and sanded off-the cost of painting can become truly staggering.
According to Remodeling magazine (October 1996), investing in new siding can prove to be an excellent choice in terms of payback. In the West, a homeowner can recoup 65% of the cost of siding in terms of resale value added to the home. In the East, the payback is 76%. In the South, it's 84%. And in the Midwest, the cost recouped is 69%.
Compare the ongoing costs of painting every three to five years to a one-time investment in new vinyl siding. For most homeowners the conclusion is obvious-vinyl siding is by far the better long-term value.
In terms of adding resale value to your home, vinyl siding is one of the best investments you can make. In its annual survey of project cost versus added value, Remodeling magazine said that "the highest payback comes from projects that give an older home the same features that have become standard in new homes."
Exterior improvements such as the installation of vinyl siding also make a home more attractive on the market. According to a real estate agent interviewed by Remodeling, "Things like new siding and new windows will not add dollar for dollar value...(but) they will cause the house to sell quicker for more money."
Another point to keep in mind: if, like many homeowners, you add insulation to an older home at the same time you're having vinyl siding installed, you add even greater value and market appeal to your home
Not when it comes to siding. Vinyl siding's outstanding features and benefits have made it the most popular siding material in America today. And because vinyl is the preferred siding for more and more homeowners, it retains most of its installed cost (see previous question for details). It's the material of choice on new luxury homes...and the first choice for remodeling projects large and small.
Leading manufacturers offer a broad range of vinyl siding products, so you can choose one that's easily affordable. Plus, most vinyl siding never needs painting or staining. It doesn't chip, peel, dent or rot, so you can forget costly repairs. To maintain a like-new appearance, just rinse occasionally with a garden hose.
And vinyl siding offers flexible design options that make it ideal for contemporary homes...and for stately century-old Victorians. You can choose from smooth or grained surfaces; rich, low-gloss colors; and a wide variety of classic siding profiles-plus low-maintenance trim products and accessory options that add to both the beauty and value of your home.
What's more, vinyl sidings are backed by a strong warranty, so you can count on getting all the quality you paid for.
Exceptional beauty. Durability. Economical price. Easy maintenance. Long-term value. Outstanding warranty. If these are your criteria, there's no better choice than vinyl siding.
Absolutely. The correct technical name for the material used in vinyl siding is polyvinyl chloride. It's a strong, durable, proven material that has earned a solid reputation for its beauty and permanence. It's used in automotive applications, medical devices, defense weapons, appliances, floor coverings, and of course, home construction.
It's ideal as an exterior material because vinyl siding doesn't rot, crack, dent or warp. Plus it never peels or blisters. And because the color goes completely through most siding, it never has to be scraped, sanded or painted.
First and foremost, make an informed decision. Require references and look at previous work. Word-of-mouth recommendations from neighbors or friends who have recently re-sided their houses are an excellent start. You may also want to ask about liability insurance, customer satisfaction policies and professional credentials.
The relationship you have with your contractor is extremely important. Choose someone whose skills you trust, someone qualified to perform the task required, and someone you can work with comfortably.
It's simple. There really is no maintenance, just occasional cleaning.
Ordinarily, the cleaning action of a rainfall will be adequate to wash your vinyl siding. However, vinyl siding and soffit should be washed periodically by hosing with a garden hose and clear water, particularly in those areas not exposed directly to rain. If you desire to do a more thorough cleaning, or where high soil collection conditions occur, use a soft-bristled, long-handled washing brush. It attaches to your garden hose and makes washing your siding easier.
Not really. You can have your vinyl siding installed in any season, as your schedule and budget allow. But keep in mind that some contractors are more available during the off-seasons. Regardless of when you have your new siding installed, you'll enjoy the immediate benefits of improved appearance, as well as the long-term benefits of durability and easy maintenance.
A true replacement window is a window that's custom built to fit within the opening of an existing window. It's built to fit precisely and can be installed without disturbing the interior and exterior areas around the window.
Because custom windows are made to fit perfectly, they provide the best energy efficiency (which saves energy costs) and install much more easily and with very little mess. Also, because of the myriad of options available that affect appearance and efficiency, custom windows allow consumers to designexactly the windows they need or want.
Standard windows typically cost less in the beginning, but other expenses and factors—like additional labor and the disruption to the home—far outweigh the original savings. For example, installing stock windows requires that you add brick or siding to the exterior, and drywall or other materials to the interior. In addition, custom-made windows allow you to choose the best solution to the problems you want to solve by replacing windows.
It's true, if you select high-quality, energy-efficient windows. Savings will vary, but expertly engineered and well-built windows lower home energy consumption. With vinyl-framed windows, maintenance is also virtually eliminated. No need to scrape and paint windows.
These energy and maintenance savings will allow you to recoup your window investment over time.
Years ago that may have been true. However, today—with the options available and with advances in window design technology—quality vinyl windows are both beautiful and unique. For example, home owners can choose from sculptured or sleek window styles; white, almond or woodgrain vinyl finishes; standard or diamond grids; and beveled, leaded, etched or stained glass. And these are just a few of the options available.
There are still old fashioned, low-end vinyl windows available, but the new designs are beautiful, maintenance-free and energy efficient.
Actually, no. Condensation is moisture vapor suspended in the air, and that's something no one can guarantee to eliminate. However, high-quality vinyl windows incorporating warm-edge technology glazing systems will help to reduce condensation because they're much less thermally conductive than other window types. They can help keep the temperature of the window warmer—minimizing the hot and cold differences that turn moisture into condensation.
Many high-quality windows are actually engineered to make cleaning easier. For example, double-hung windows with the latest internal constant force balance system allow a home owner to easily maneuver the sashes up and down. They tilt in—and lock securely in place—for safe, easy cleaning. Quite a difference from old wood windows that stick and are difficult to move up and down.
Insulating glass consists of two pieces of glass sealed to a spacer. This creates an insulated air space between the two pieces of glass, resulting in better thermal performance. Insulated glass also reduces condensation while keeping the heat in during the winter, and heat out during the summer.
Low-E (Emissivity) glass is treated with thin, virtually invisible, transparent coatings of various layers including metal oxide and silver. During the winter, Low-E glass allows the sun's natural light and short-wave heat energy to freely pass through while reflecting long-wave heat energy back inside, keeping your home warmer. In the summer, Low-E glass reflects long-wave heat energy to the outside keeping your home cooler and, reduces the penetration of the sun's ultraviolet (UV) rays, minimizing the fading of carpet and draperies.
Krypton Gas is an inert, odorless, colorless, tasteless, non-toxic gas that is denser than air. It is used to replace air between the glass panes in an insulating glass unit to reduce temperature transfer and deter convection (heat transfer by currents that flow from a warm surface to a colder surface).
R-value measures the resistance a material has to heat flow. The higher the R-value, the greater the resistance, and the better the insulating quality.
U-value measures the amount of heat transferred through a material. The lower the U-value, the slower the rate of heat flow and the better the insulating value.
Conduction refers to the energy transfer from one material to another by direct contact.
Look for the National Fenestration Ratings Council (NFRC) label on the window or patio door. This label shows the U-Value, Solar Heat Gain, visible light transmittance and condensation resistance values.
Yes. Though any new addition can increase the value of your home. We set all of our screen rooms up to receive windows if you would like to up grade your screen room in months or years form now.
Absolutely. Four-legged family members can have their own private entrance and exit with screen rooms and window-ready rooms.
The performance and longevity of vinyl windows compare very favorably to those of other building materials, and vinyl often costs less to produce. Vinyl windows and doors are rapidly capturing a major market share as more builders and homeowners learn about vinyl's outstanding value and economy.
Long-lasting beauty, low maintenance and excellent thermal efficiency ratings give vinyl windows a winning edge over other types of replacement windows. The vinyl compound is produced with extra levels of UV inhibitors to help withstand harsh weather conditions, and it is recyclable and environmentally friendly. Vinyl won't pit or peel over time with only simple care and cleaning, windows can keep their beautiful appearance for years to come.
Elite’s advanced construction is unmatched for durability and technological enhancements, and all connections are smartly concealed from view and protected from the elements to provide years of dependable service. Superior design and heavier gauge materials allow for far greater spacing between columns than other sunrooms, providing options for more open spaces without compromising structural support.

Yes. Several products are available. One is a pet resistant screen. This pet resistant screen is ten times stronger than a regular screen. The animal, whether it is a dog or cat, cannot break the strands; however, if they chew on it, they will be able to shred it. Another product is a super-screen, which is about five times heavier than a regular bug screen. This screen gives you great outward visibility. It's not as strong as a pet screen, as it is designed for insect control, but it can tolerate a considerable amount of pet abuse
Yes, we do patio enclosures all over Middle Georgia. Patio enclosures can be custom designed to fit your home, using different types of screen. They are constructed adding double or single doors, with chair rails and kick panels. Frame and fabric choices are available in several colors which enable you to customize it to blend with your home.
Yes, aluminum screen is still available and no, it is not as strong as it was years ago. Manufacturers are no longer producing heavy weight aluminum screening material. Currently produced aluminum wire screen is lighter and easier to work with but is less durable. Most screeners are using fiberglass screen fabric as their primary material, although aluminum wire is still available on request and for certain circumstances.

Seamless gutters are nationally recognized as the most popular form of guttering. It eliminates unsightly seams and reduces the possibility of leaks. There are many colors to choose from and the baked on enamel finish never needs painting. Seamless gutters protect the beauty of your home and expensive landscaping. Fabricating on the job provides you with a custom fit. Most jobs are completed in one day.
Having dirty, clogged gutters prevents waterflow and in some cases can be worse than having no gutters at all. If you do not have the time or ability to clean your gutters and perform regular maintenance, then you will want the protection of gutter guards. Gutter guards help prevent clogs, birds nests, debris, and plant life from building up in your gutters while still allowing water to pass and drain through your gutter system.
How you tolerate maintenance on your home will determine when you should replace the gutter. If you're the kind of person who doesn't want to be bothered with the time and money repairs demand, you should replace your gutters at the first sign of rust. Rust will often show up as little orange speckles that show through the paint, rusty colored stains at the end of the downpouts, or at gutter seams that are separated and leaking. Gutters rust from the inside out. When they begin to show rusting on the outside, the inside is rusting through. Often, however, because of standing water, the gutter may need to be repaired in just one or two areas. Keep in mind that just like a worn suit, you can't keep patching it forever. You may want to repair them for the rainy season, and plan on having them professionally replaced during the off season.
How your gutter is fastened, is just as important as the type of gutter you select. We use the hidden hanger system. The hidden hanger is a bracket that clips under the top of the front gutter hem and is secured to the back. The bracket is then screwed into the fascia board with a wood screw. Since it's inside the gutter, it is not visible. This system also allows easy removal of the gutter, should it ever become necessary.
It's hard to find a web site to just quote you a price. There are many variables involved in determining a price. From landscaping around the house to the number of levels from the ground the gutters will be installed at. A professional estimate should be done on your house to obtain an accurate price. We will provide you with a free estimate.
Absolutely! Rain barrels can be used to gather the water that is collected by the gutters. Using gathered rain water in your yard through hoses will reuse valuable water and help save on your utility bill.
As with most home projects, a homeowner can install gutters themselves. The inherent risk with “do-it-yourself” projects is the effect it can have on your home and your wallet. In the case of gutters, if they are not installed properly the home can be damaged by run-off water, which can result in structural damage, mold growth and foundation decay. It is always best to choose a qualified and insured contractor for any home improvement project.
Unless you have a very large or complex house, we will haveyour work completed in one day.
The answer is NO.
All rain gutters do the same job. They catch the rain water that falls from your roof, then contain and control this water to the ground.
However, rain gutters come in all shapes, sizes, materials, colors and quality. Some are pre-formed and joined together with connectors (such as the gutters you buy at your local lumber yard), and some are custom made specifically for your home (seamless).
Because the seamless type of rain gutter is custom made, the material used, the various component parts, the layout plan, the installation, and the quality of workmanship will not be consistent from company to company.
There is no "best gutter". There is the best gutter for the job. As with most products, there are strong points and weak points in the various rain gutter systems. For most homeowners, seamless aluminum (continuous aluminum) rain gutter will give you the most bang for the buck. It's available in about 20 colors and Aluminum coil usually comes painted from the factory.
Seamless Copper is considered the top of the line. It can last for hundreds of years. Copper carries a certain "status". It is, of course, more expensive. Although copper doesn't take paint well, few people who buy copper actually want it painted. Copper will oxidize and the oxidation is turquoise.
This is similar to rust on steel, except it is not caused by the metal breaking down (corrosion). The resulting "patina" finish is a very sought after look. This turquoise marbling adds texture, color, and a richness to copper that is unequaled by any other metal. But like rust it can stain. If you live in an area that has a heavy marine layer, be aware that you may experience some staining from the condensation that drips off the copper gutter.
for appearance purpose. This is usually done when you wash the rest of the home. Aluminum gutters are mostly maintenance free, however you may want to wash them every couple of years.
Yes, unless we need to go around inside or outside 90 degree corners.
Waterborne, Creosote, and Oil-borne (penta) are the three broad classes of preservatives typically used when pressure-treating wood.
Wood treated with waterborne preservatives is typically used in residential, commercial and industrial building structures. Creosote is primarily used for treating railroad ties, guardrail posts, and timbers used in marine structures. Oil-borne (penta) is most often used for treating utility poles and cross arms.
Several typical waterborne preservatives used in building applications include: Chromated Copper Arsenate (CCA-C), Alkaline Copper Quat (ACQ-C, ACQ-D, ACQ-D Carbonate), Micronized Copper Quat (MCQ), Copper Azole (CA-B & CA-C, μCA-C) and Sodium Borates (SBX/DOT).
These treatments are often referred to by trade names such as: Wolmanized Natural Select™ (Copper Azole), Preserve and NatureWood® (ACQ), MicroPro™, Smart Sense™ (MCQ), and Advance Guard® (Borate). Each preservative usually has a number of variations available so care should be exercised when specifying treated wood.
Some different oil-borne preservatives that are used are Chlorpyrifos/IBPC, Copper Naphthenate and Pentachlorphenol. One advantage of these treatments is that they do not create swelling in the wood, but there is generally an added cost over water-borne treatments as well as availability in some regions.
Pressure treatment is a process that forces chemical preservatives into the wood. Wood is placed inside a closed cylinder, then vacuum and pressure are applied to force the preservatives into the wood. The preservatives help protect the wood from attack by termites, other insects, and fungal decay.
Retention level refers to the amount of preservative that remains in the wood after the treatment process is complete. It is measured on a weight basis and is typically expressed as pounds of preservative per cubic foot (pcf) of wood.
There are a number of typical retention levels available. Generally, the harsher the condition the wood is exposed to, the higher the retention level must be
Higher chemical content refers to wood for ground contact with specified retention levels greater than
0.40 pcf for ACQ
0.34 pcf for MCQ
0.21 pcf for CA-B
0.15 pcf for CA-C and MCA, or
0.14 pcf for μCA-C.
Where fasteners are in contact with preservative-treated lumber, high exposure refers to wood with specified retention levels higher than
0.15 pcf for ACQ,
0.15 pcf for MCQ,
0.10 for CA-B,
0.06 pcf for CA-C and MCA, and
0.05 pcf for µCA-C.
In these cases, stainless-steel connectors and fasteners, or copper or silicone bronze fasteners are recommended.
For retention levels higher than those listed above, consult our Guidelines for Selecting the Proper Materials and Coatings. See treated wood industry web sites for other use/exposure categories and retention levels.
Trees / logs from which commercial wood is cut have a number of different layers. The two primary layers are called heartwood and sapwood. Heartwood provides most of the "structural" strength to the living tree while the sapwood transports the sap from the base of the tree up to the leaves.
Wood preservatives penetrate sapwood easier than heartwood. As a result, wood species such as Southern Pine, which have a high percentage of sapwood, are predominately used in pressure treating.
Wood species such as Douglas Fir have more heartwood so modifications are typically required to the preservative to achieve adequate penetration and retention levels. The modification that is usually made is to change the "carrier" used in the preservatives. Often this carrier uses an ammonia base, which improves the penetration but also tends to increase the corrosivity of the preservative. (The carrier used to treat sapwood species usually has an amine base.) This increase in corrosivity may be short term or long term. Hybrid carriers, a mix of amine and ammonia bases, may also be used to treat heartwood species.
Incising (perforating the wood with small slits) may also be utilized to increase the penetration of preservative in heartwood species
Chromated Copper Arsenate (CCA) has been used successfully for a number of decades for pressure treating wood. Several types of CCA have been used, however, CCA-C (type C) has been the predominant preservative used for wood likely to come in contact with the products Simpson Strong-Tie manufactures.
In recent years preservative treated wood received negative publicity mainly focused on the use of arsenic in CCA. The increasing pressure to eliminate the use of CCA resulted in the treated wood products industry voluntarily transitioning from CCA to alternative preservative systems.
CCA is no longer being produced for residential or general consumer use.
CCA treated wood products are still produced for use in some industrial, highway, and agricultural applications. These uses will include wood used as poles, piles, guardrail posts, and wood used in saltwater marine exposures.
A number of alternative preservatives are available. These include ACQ-C (Alkaline Copper Quat Type C), ACQ-D Carbonate (Alkaline Copper Quat Type D, Carbonate formulation), CA-B/ CA-C (Copper Azole Types B and C), µCA-C (Azole biocide), as well as SBX/DOT (Sodium Borate) and Zinc Borate preservatives. As mentioned earlier, each preservative usually has a number of variations available so care should be exercised when specifying treated wood.
It is expected that the formulations used in these products will continue to undergo periodic modifications so once again, care should be exercised when specifying any treated wood.
Testing has indicated that some of the alternative products are more corrosive to steel and some protective coatings applied over steel than Chromated Copper Arsenate (CCA-C). Contact the treated wood chemical supplier for more information.
Hot-dip galvanized or stainless steel fasteners, anchors and hardware are recommended by the Preservative Treated Wood Industry for use with treated wood. This has been the position of this industry for years and their position has not changed with the transition to the alternative copper-based products. In the past this industry did not address the required levels of galvanizing, however most of those in the industry now provide information regarding the minimum level of galvanizing that should be used.
The thicker the galvanized coating the longer the expected service life of the fastener, connector, anchor, or other hardware will be.
Electroplated / electro galvanized and mechanically galvanized coatings should not be considered to be hot-dip galvanized. (Class 55, or higher, mechanical galvanizing provides galvanizing equivalent to the hot-dip galvanizing used on connectors and fasteners. Ref. ASTM B695 for additional information.)
It is also worth noting that the galvanized coating thickness varies depending on the galvanizing process used. Remember, the thicker the galvanized coating, the longer the expected service life of the steel will be.
Refer to the different chemical manufacturers and/or treaters as well for their recommendations. A list of trade names is included at the bottom of this page.
All stainless steels may not be acceptable for use with preservative treated wood. Testing has shown that Types 304, 305 and 316 stainless steels perform very well with woods that hay have excess surface chemicals. Type 316 stainless steel contains slightly more nickel than other grades, plus 2-3% molybdenum, giving it better corrosion resistance in high chloride environments prone to cause pitting such as environments exposed to sea water.
Hot-dip galvanizing is a process of providing a protective coating (zinc) over bare steel. The bare steel is cleaned, pickled, fluxed, then dipped in a molten bath of zinc and allowed to cool prior to inspection and shipping. Additional information is available at www.galvinfo.com. Some anchors and fasteners can be hot-dip galvanized. Steel connectors can be hot-dip galvanized (see below: “What is the difference between Simpson Strong-Tie's Hot-Dip Galvanized (HDG) products and products that are hot-dip galvanized after fabrication?” for additional information.)
Terms such as G90 & G185 reflect the galvanized coating thickness that meet the ASTM A653 specification for sheet steel.
Mechanical galvanizing is a process of providing a protective coating (zinc) over bare steel. The bare steel is cleaned and loaded into a tumbler containing non-metallic impact beads and zinc powder. As the tumbler is spun, the zinc powder mechanically adheres to the parts. The zinc coating has “good” durability, but has less abrasion resistance than hot-dip galvanized zinc coatings since it does not metalurgically bond with the steel. Some anchors and fasteners can be mechanically galvanized.
ZMAX® is a thicker coating (galvanized per ASTM A653 with a G185 coating) than the standard hot-dip galvanized coating (galvanized per ASTM A653 with a G90 coating). This thicker coating is available on select Simpson Strong-Tie connectors. Due to this increased galvanized thickness these connectors would be expected to have a longer service life than standard galvanized connectors. See Simpson Strong-Tie Material and Coatings Available for additional information.
There are two processes used to hot-dip galvanize parts: (1) “continuous” hot-dip galvanizing (“Continuous HDG”) and (2) “batch” or “post” hot-dip galvanizing (“Batch/Post HDG”).
Continuous HDG is generally used to galvanize steel coils at various speeds (up to 600 feet per minute) on thinner gauge steels (galvanized per ASTM A653). Simpson Strong-Tie uses this type of steel to fabricate most thinner gauge products.
Batch/Post HDG is generally used to galvanize heavier individual parts not capable of being fabricated from galvanized steel coils (galvanized per ASTM A123 for connectors and ASTM A153 for fasteners). After being fabricated, the parts are dipped into molten zinc for a longer period of time than Continuous HDG, usually resulting in a thicker coating and more protection against corrosion. Batch/Post HDG can be used on Simpson Strong-Tie connectors, such as CC and CB column caps and bases and thicker gauge hangers(14 gauge and thicker).
