King StarBoard® is the original marine-grade high-density polyethylene (HDPE) building sheet from King Plastic Corporation — the industry standard trusted by professional boat builders and marine fabricators for over 30 years. This sheet measures 3/4 inch thick x 24 inches x 54 inches in a classic Black color with a matte finish on both sides.
Manufactured using King Plastic's proprietary K-Stran™ process, King StarBoard delivers superior flatness and consistency that competing HDPE sheets cannot match. It is environmentally stabilized with UV inhibitors and built to withstand the harshest marine conditions — it will not rust, warp, rot, or delaminate when exposed to UV, humidity, or water.

King StarBoard is the go-to replacement for teak and other wood components in marine environments. Unlike wood, it will never delaminate, absorb moisture, or require seasonal maintenance. Its matte black finish coordinates with most boat gel coats and hides minor surface scratches for lasting good looks. Ideal for helm stations, tackle centers, leaning posts, rod holders, cutting boards, hatches, consoles, and virtually any custom marine fabrication project.
