King StarBoard® is the original marine-grade high-density polyethylene (HDPE) sheet and the industry standard, trusted by marine professionals for over 30 years. This 1/2-inch thick, 24" x 54" White/White sheet features a durable matte finish on both sides and is manufactured using King Plastic's proprietary K-Stran process — the most advanced method available for producing consistently flat, uniform HDPE sheets.
Engineered specifically for the demands of the marine environment, King StarBoard® is environmentally stabilized to resist the harshest conditions on the water. It will not warp, rot, swell, splinter, or delaminate when exposed to UV, humidity, or water — making it a superior, low-maintenance alternative to teak and other traditional marine woods.
