Deck Framing & Drainage Systems

A behind-the-scenes performance

The mark of truly smart design occurs when the pieces you don’t see are as innovative as the beauty you do. Our under-deck drainage and framing systems are as smart as our high-performance decking, making Trex® an all-around luxury partner for the outdoors.

Trex Elevations Steel Deck Framing creates a solid foundation on which to build your high performance composite deck.
Trex Elevations® Steel Deck Framing

By designing an under-deck framing system with the outdoors in mind, we've reinvented the concept, creating a remarkably stable and consistently flat, triple-coated steel substructure on which to build a high-performance deck—something other deck frames could only dream about.

Prevent drips and keep the area under your deck dry with Trex RainEscape, it's under deck drainage system.
