MARINE-GRADE COMPOSITE DECKING

Build It Once. Enjoy It for Life.

Lumberock® is composite decking and plastic lumber made from high-density polyethylene and inorganic mineral fillers — zero wood fiber, zero organic filler. It won’t rot, split, crack, or splinter, and it never needs sanding, staining, or sealing. Five collections, one material standard, for decks, docks, porches, and the projects that ask more than a deck does.

SHOP BY COLLECTION

Five collections. One material standard.

TIMELESS STYLE

Classic Collection

The broadest lineup in the family.

Deck boards, tongue-and-groove, balusters, 4x4s and more, in twelve natural colors and lengths up to twenty feet. The all-purpose Lumberock path for decks, docks, and boardwalks.

  • Twelve natural colors

    The widest color range Lumberock offers, across dimensional deck and railing boards.

  • Twelve profiles

    Deck boards, tongue-and-groove, balusters, and 2x and 4×4 dimensional lumber.

  • Lengths up to 20 feet

    Longer boards mean fewer seams across decks, docks, and boardwalks.

  • No sealing, ever

    Clean it periodically with soap and water. No sanding, staining, or sealing.

SHOP BY PERFORMANCE

The parts of the material story that decide most projects.

Every Lumberock collection carries the same performance standard. These are the six places it shows up first.

MARINE GRADE

Built to get wet, and to stay that way

HDPE and inorganic mineral fillers with no wood fiber inside, so the board performs the same wet or dry. Docks, splash zones, humidity, and coastal air included.

NO ROT / NO WOOD FIBER

Take the organic material out and rot goes with it

Rot needs moisture and organic material working together. Remove the wood fiber and the organic filler, and the wood-based rot pathway is gone.

LOW MAINTENANCE

No sanding. No staining. No sealing.

Once installed, a Lumberock project asks for very little. Clean it periodically with soap and water and it keeps looking new.

HEAVY-DUTY LUMBER

For the projects that chew through wood

Commercial surfaces, agricultural buildings, custom builds, and specialty work where a material failure gets expensive fast.

PROFILE FLEXIBILITY

A material system, not a one-board answer

Deck boards, tongue-and-groove, balusters, and dimensional profiles, so the board can match the way the project is actually built.

24" ON-CENTER SPAN

A spec advantage when the application supports it

Wider approved joist spacing can simplify framing, estimating, and material planning on the Lumberock products and profiles that carry it.

THE MATERIAL DIFFERENCE

What’s inside the board is the whole story.

Wood rots because it is wood. Most composite boards still carry wood fiber and organic filler, which keeps the same failure pathway alive inside the board. Lumberock takes it out: high-density polyethylene plus inorganic mineral fillers, made with recycled material and fully recyclable, in a board that performs the same wet or dry.
