Lumberock Decking

Lumberock® Composite Decking Built for adventure. Trusted by the coast. At Lumberock®, we don’t just make decking—we engineer the last deck board you’ll ever need. Using advanced extrusion technology, we combine high-density polyethylene plastic with a unique mineral-fill compound to create solid, non-porous profiles that outperform traditional materials. Our boards are: Tougher than the elements – They won’t rot, crack, splinter, or peel. Low-maintenance – No organic fills mean nothing for mold, mildew, or bacteria to cling to. Marine-grade – Proven to endure prolonged submersion in saltwater and freshwater. Stronger & more stable – Mineral-fill additives increase strength and reduce thermal expansion. From coastal marinas to backyard escapes, Lumberock® is trusted by outdoor enthusiasts, homeowners, and professionals who demand lasting performance. Every board is backed by our Limited Lifetime Warranty—because durability isn’t just a feature, it’s our promise.
