How to Install Composite Deck & Porch Railings
Composite guard railings offer a low-maintenance option for railing. Most low-maintenance decking manufacturers offer one or more railing systems to compliment their flooring products. You will have the opportunity to choose from a variety of colors, styles and options. These systems are available in kits that are relatively easy to install.
These systems use 4x4 pressure-treated wood posts covered by a sleeve and mounted to either the inside or outside of the frame. Each railing section can be easily installed between posts using brackets provided in each kit. Stair railing kits are also available for ease of installation.
Build a jig using scrap material to assist in drilling the baluster connector locations. The width of this jig was cut to 1 1/4" wide to fit inside the channel in the top rail and center on the bottom rail. The manufacturer recommends 4 3/8" on center spacing for 3/4" steel balusters. If you plan on tightening your spacing of balusters, make sure you order extra balusters.
Set your jig to balance the layout of your balusters along the top and bottom railing. You may choose to center a baluster or space at the center of each section of rail. The jig makes it easier to choose the most attractive layout. You don't want a baluster installed too close to the rail posts. Use your jig to pre-drill the baluster connector locations.
