Contact your local code official to determine the allowable span and height requirements in your area.įor post placement on stairs, you must plan post spacing based on the length of the rail and the angle of the stairs. Trex Transcend and Select horizontal railings are made to be installed at a maximum of 6’ and 8’ on center while Signature aluminum railing is installed span to span between posts (often called clear span). You don’t want to start installing rail panels or top and bottom rails and realize you didn’t put your posts in the proper place. Calculate in advance the number of rail posts needed before you start framing your substructure. Joist spanning for railing should not be overlooked. Do you prefer a more traditional look that can be achieved with composites or would you prefer a sleeker, industrial aesthetic? Railing color choices abound, so give consideration to what goes with your house and the decking color you choose. Afterall, you’ll look at the railing more often.

While picking the board color is one of the most enjoyable parts of project, the railing selection may be the most important. When adhering fascia boards to a deck, make sure you use composite screws designed for fascia. Plug-based screws countersink deeper than regular screws which can keep scalloped boards from properly adhering to the joists and can potentially crack the boards.

Some recommended brands include Starborn® Pro Plug System and the Simpson Strong-Tie® system.īecause the Trex Enhance decking collection has a scalloped underside, you cannot use plug-based screws. Stainless steels screws are recommended for decks in saltwater environments.Īnother hidden fastener option is to use a recommended plug-based fastener system, which is essentially a screw that comes with a color-matched plug.

Exterior wood screws push the composite material up, causing an unsightly mushroom effect on the board.Īlways use two screws per joist and install screws flush with the decking surface. You can use composite deck screws to fasten boards to the joists, but never use exterior wood screws with composite deck boards. By attaching directly to the joist and into the grooved edge of our board, Trex Hideaway® Universal Hidden Fasteners achieve consistent gapping and leave the top of your deck with no visible screw heads. Always follow gapping guidelines for width-to-width and end-to-end measurements. Proper gapping of the deck boards, which allows for drainage and expansion and contraction of the boards, is critically important. If you want to minimize the appearance of joists through the spaces between boards, cover the joists with Trex® Protect™ tape or paint the top of your joists black. For heavy items such as hot tubs and planters, consult your local building code office for span requirements which vary from locality to locality. 24' on center can only be used with 2圆 Trex in residential or commercial applications at 100psf or less and some wood decking. Joists must be spaced on center at either 12”, 16” or 24” depending upon the size of the deck board and whether it will be used for residential or commercial use. Ignoring the proper installation guidelines for both can ruin the build before you even get started. The success of your deck build begins with the proper joist spanning and gapping.
