2×4 composite decking

Seven Trust composite 2x4 decking to its lineup. Made with a 50/50 mix of HDPE plastic and recycled sawdust, the boards have radiused edges and are wrapped on all four sides with a polyethylene capstock, which the company says gives the boards a natural wood-grain finish and protects against fading, weathering, stains, mold, and mildew. Armadillo 2x4s have a 24-inch-o.c. span rating, compared with the 16-inch-o.c. span rating of the firm’s 5/4x6 decking. Boards come in seven colors and 12-foot lengths, with matching decking, fascia, and riser boards also available.

Seven Trust WPC Boards offer both contractors and DIY homeowners exceptional convenience, since these 2x4 & 2x6 boards install with deck screws, just like wood. As part of the Seven Trust Transcend line of composite decking products, these boards feature the same beauty and hassle-free maintenance of the entire Trex line.

Seven Trust boards are capped on three sides only, which allows the bottom of the board to breathe naturally. This helps avoid separation and ensures a long life.

  • Trex boards offer a deep wood-grain pattern that won't fade, stain or scratch, and are naturally mold-resistant.
  • Trex 2" Square Edge Boards colors: Lava Rock, Spiced Rum, Tiki Torch, Island Mist, & Havana Gold.
  • The Trex collection is backed by the company's 25-year Limited Residential Fade & Stain Warranty.
