24 LC DBM winds facing gusts up to 130 mph." "You also have the aluminum bottom channel between the two posts, which is rather unique," adds Premac. "Other fence types will sleeve the bottom rail with the material, be it wood or steel." But in this case, a ¾" thick piece of aluminum actually is the bottom rail – it is not being sleeved. A common application for the fencing product is to mount it to concrete pads or walls for such things as hiding me - chanicals and minimizing noise. Also, the product works well on slopes as the posts and pickets can be cut at an angle, or transition cut, like wood. The sys - tem also allows for racking: adjusting the angles of the sections, as opposed to having to "stair step" the sections, which leaves gaps between the ground and the bottom of the fence, making it less secure. The wood composite system also fa - cilitates installations in areas with bed- rock bases. "They (drill) down to 60 inches or so," Premac reveals, "run a 12-foot post and then sleeve it with an 8-foot or 9-foot galvanized steel insert that will have a further depth and set that in the concrete right inside the rock." A popular customer for wood com - posite fencing is homeowners associa- tions, with Premac calling it a one-time, upfront investment. "There is basically zero maintenance, so the HOA reserves can be diverted to painting, landscaping, snow removal and such," he says. "The break even on the payback versus wood is typically 12-14 years." And the product's noise abate - ment qualities make it a cost effective option for commercial and industrial applications. "Other solutions are usually consid - erably more expensive, thus at times unavailable," Premac explains. LC DBM Above and Left To accom- modate grade change, a lot of fences use the stair step method but this creates gaps, which reduces the security qualities of the fence. Wood composites, like wood, allow for a tran- sition cut, as pictured here, by simply cutting the posts and pickets at an angle. Left, Above and Right A second method to mount a wood composite post into concrete is to: (1) Weld a Z-channel to a 3/8" plate. (2) Drill four holes into the concrete, fill with epoxy and attach the channel and plate with ½" concrete anchors. A Z-channel works well for this because it allows better access for fixing the bracket into the concrete. (3) Sleeve the post over the mount, plumb it and secure it with self-tapping screws. 1 2 3
