Marine Board

(SEABOARD, STARBOARD, DENSETEC, ETC.)

FABRICATION GUIDELINES

SKIP TO PRICES

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.

Before  After replacement with Marine Board

In addition, there is no need to stain or paint Marine Board every few years. The color is integrated with the polymer and retains its vibrant appearance better than painted wood.

Marine Board Standard Colors

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.

Standard Colors: Polar White, Seafoam, Sand Shade Stone Grey, Light Grey, Dolphin Grey, and Black. Colors can also be matched to your exact requirements.

Standard Size: 54"x96". Other sizes available upon request

Standard Thicknesses: 1/4", 3/8", 1/2", 3/4", and 1". Other thicknesses available upon request.
