Ramp it Up
Decking and Railing Materials Can be Used for a
Variety of Applications, Not Just Outdoor Spaces
by Samantha Carpenter, editor of Shelter magazine.
William Orsi has built many ramps for both commercial and residential
properties, but the owner of the deck building company, Deck Builders 4 Hire
in Richmond, Va., says his favorite accessibility ramp was built for an area
church in order to provide its physically challenged members easy access to
For the project, Orsi used pressure-treated Southern yellow pine, concrete pier blocks and hot-dipped galvanized hardware (nails, bolts, washers, etc.). The project took him approximately two days, and he says ramps are usually straight-forward projects, but these types of projects do give him great pleasure.
Instead of it being something for just one person, for instance, it will provide a greater service for many people, of various age groups, Orsi says.
There is a market for materials usually used for decking and railing systems for aging-in-place and Americans with Disabilities (ADA) applications.
According to the National Aging in Place Council, The entry to [a] home is [its] connection to the rest of the world Barrier-free entryways make it easier for a family member or friend who uses a wheelchair, or a grandchild whos on crutches because theyve broken a leg or twisted an ankle, to gain access to [a] home.
Many of you are already distributing outdoor products, including railings and decking, but you may not know that many of these products arent only used for decks but they can be used to build accessibility ramps to make a barrier-free entrance to a home or business.
If you arent familiar with the different attributes of the outdoor products you sell or distribute, then you could be missing out on a potential market.
I think [constructing ramps] is an opportunity for contractors that maybe they havent thought of, especially contractors that have built decks, says Huck DeVenzio, manager of marketing/communications for Arch Wood Protection in Smyrna, Ga. Ramps arent that much different than a deck. With the ADA laws, theres a need for ramps on a lot of buildings.
Jerry Tracy, a sales representative for Fiberon products, located in Columbus, Ohio, backs up what DeVenzio says.
Tracy says his company, which manufactures a composite decking product, started using it mainly in commercial applications, but lately he has seen the product being used more in residential work.
I had a builder who just called me up last week in Columbus that is going to put in a ramp, he says.
With any building project, companies say there are advantages to using different types of materials, such as treated wood, vinyl or composite products.
Wood proponents tout its products durability, rot resistance and more.
Wood makes a good choice and treated wood is the sensible choice because you dont have to worry about it rotting or collapsing, DeVenzio says.
Richard Kleiner, director of pressure treated markets with the Southern Forest Products Association in Kenner, La., says treated wood has been used in access ramps because it has high strength and treatability.
Most access ramps are usually installed in the weather and treated Southern pine has excellent resistance to rot and other pests that attack wood, such as termites. Treated Southern pine will last decades, he says.
He does say that the species of wood used on these types of projects is a regional preference.
Generally codes are going to require some sort of treated wood or a naturally durable wood like a cedar that can be very expensive. Southern treated pine is economical, widely available, easy to work with and doesnt take any special tools, he adds.
There are also wood products available that arent treated with chemicals.
Ron Long is president of Purewood in Kansas City, Mo., one such wood decking company.
People like wood and working with it, and we make a little bit thicker board thats 1 1/4-inch thick instead of standard decking that is 7/8- to 1-inch thick, Long explains. Its a little bit beefier deck board. Its a non-toxic, chemical-free outdoor wood product.
Vinyl and composite decking materials also have their benefits, and most companies plug the products low-maintenance qualities.
The Low-Maintenance Appeal
Deron Manwaring, national marketing and sales manager for Royal Outdoor Products in Milford, Ind., says his company had one of the first vinyl deck products on the market.
When it was designed it had codes in mind and especially ADA codes, such as slip resistance on any kind of ramp or the space between the boards, Manwaring says. Most of the ramps that are used are used in places and facilities that want to keep their maintenance to a minimum, and products that they dont have to replace. Our decking has a great surface for ramps, but most of those ramps need railings to go along with it, and a vinyl railing system makes sense as it needs minimal maintenance, too.
TimberTech offers a 25-year limited warranty on the product, so those homeowners who are looking to design with the future in mind know they arent going to spend as much time as compared to a pressure-treated deck, explains Rob Foster, TimberTechs spokesperson. It becomes a very low-maintenance option for them, and it can provide a greater benefit over a period of time. All the decking products are ADA-compliant for slip resistance.
Foster says hidden fasteners are also important.
These decks are grooved and allow for hidden fasteners, which are really important because with regular pressure-treated lumber, most decks are secured by nail and/or screw and with those boards expanding and contracting with the heat and the water, the fasteners can possibly pop outand thats about the last thing you want to have on a ramp when you are on a wheelchair. The possibility of having the concealed fastener is very important in terms of safety, Foster says.
Not so Slick
Jodene Wheeler, marketing representative at CertainTeed in Valley Forge, Pa., for railing and decks, says because the companys product is vinyl, there is not a lot of maintenance that is involved with it. For a commercial project, our product is guaranteed for 30 years, she says.
Our products are used in a variety of places because they are vinyl. The deck material is cool to the touch and is very textured, [so its perfect for] someone that is a little unsteady on their feet or a wheelchair is needed, Wheeler says. When some people think of vinyl, they think plastic and think when it gets wet it is going to get real slippery, but our product is very slip-resistant.
Brent Gwatney, vice president of sales and marketing for MoistureShield in Springdale, Ark., also boasts of the low-maintenance benefits of his companys product.
You arent going to have the standard maintenance you are going to have with a wood product. You are still going to have to wash and clean it, but you arent going to have to replace it, but its not going to wear like a treated lumber deck thats wood in the same amount of time, Gwatney says.
He says that his companys product is used in a number of ramp projects, but he explains that these projects arent always without headaches.
We do quite a few of them and there is some confusion out there on ADA Guidelines or what they would call acceptable. ADA doesnt have an official slip-resistant test, but they have recommendations. And while some products dont meet the slip-resistance recommendations, it doesnt mean that they dont meet slip-resistance coding. So it can be confusing at times, and it depends on who you work with and in what area of the country, Gwatney explains.
And Gwatney is exactly right. There are American with Disabilities Act Accessibility Guidelines (ADAAG), but they are not binding on private residences. However, the ADAAG provides important guidance for building a residential ramp. When these requirements are used in the residential code, they are often the same or less stringent than the guidelines (see sidebar on page 18 for the ADAAG ramp instructions).
But codes and guidelines aside, if a customer comes in asking whether your decking and railing products can be used for aging-in-place and ADA-compliant applications, you can simply say, yes.
Southern Pine Ramp to the
An energetic group of volunteers, affiliated with the Home Builders Association (HBA) of Greater New Orleans, teamed up to construct a complex ramp. The ramp helped an elderly stroke victim confined to a wheelchair finally be able to safely enter and exit his home.
The Southern Forest Products Association (SFPA) worked with the local HBA and its Remodelers Council to ensure proper building practices and selection of durable materials. SFPA member Elder Wood Preserving donated the wood products for the entire project all pressure-treated Southern pine. The bi-level ramp design specified No. 2 treated Southern pine 2 by 8s and 4 by 4 posts for the framing and standard radius-edge decking on the surface. The sturdy railing adds a nice finishing touch to the ramp.
Using a versatile product such as treated Southern pine greatly simplified the construction process, says SFPAs Eric Gee: Unlike other plastic and composite materials, treated Southern Pine requires no special tools or skills.
ADAAG for Ramps
The following information can be found in the Americans with Disabilities
Act Accessibility Guidelines (ADAAG). As stated in the main article, these requirements
are usually more stringent than are required in many residential codes. You
can print a PDF copy of guidelines for ramps and other structures at http://www.access-board.gov/adaag/ADAAG.pdf.
