Black Marine Board.

HDPE (HIGH DENSITY POLYETHYLENE) is a polyethylene thermoplastic made from petroleum. It is sometimes  called "alkathene" or "polythene" when used for pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles,  corrosion-resistant piping, geomembranes, and plastic lumber. HDPE is  commonly recycled.

High Density Polyethylene Marine Board is specially formulated to withstand the rigors of harsh outdoor marine environments. It is UV-stabilized to resist damage and retain its beauty, even after years of direct sunlight. Increasingly, Marine Board is replacing wood and laminates in boating applications. It does not splinter, crack, delaminate, rot, swell or absorb water like traditional materials. Even under heavy foot traffic on yacht decks, it remains virtually maintenance-free.

Fabrication and finishing are easy with standard woodworking tools.  Marine Board forms easily for smooth curves and bends. Since there is no grain pattern, parts can be cut from any part of the sheet virtually eliminating waste for greater economy than wood. Common uses include cabinets and countertops, doors and windows, door and window frames, swimming pool equipment, swim platforms, trim and molding, steps and ladder tread, railing.
