King StarBoard® is the original marine-grade high-density polyethylene (HDPE) building sheet and the industry standard for boat building and marine fabrication. This sheet measures 1/2 inch thick x 24 inches x 54 inches and is finished in the popular Seafoam color with a durable matte-textured surface on both sides.
Manufactured using King Plastic Corporation's proprietary K-Stran™ process, King StarBoard delivers superior flatness and dimensional consistency that wood and wood laminates simply cannot match. It is environmentally stabilized to withstand UV exposure, saltwater, humidity, and the harshest marine conditions without rotting, warping, swelling, splintering, or delaminating.
Key Features:
- Marine-grade HDPE construction — will not rot, warp, swell, splinter, or delaminate
- Seafoam color runs consistent throughout the full thickness of the sheet — will not fade
- Matte-textured finish on both sides hides minor scuffs and scratches
- Environmentally stabilized against UV, saltwater, and moisture
- Easy to fabricate using standard woodworking tools — table saws, drills, routers, and blades
- Edges finish cleanly; material forms easily for smooth curves
- Never requires painting, sealing, or refinishing
- Easy to clean — resists stains and buildup
- Passes Federal Motor Vehicle Standard 302 fire test
- Precise tolerances ensure consistent color, thickness, and density
King StarBoard is the preferred replacement for teak, wood laminates, and other traditional marine building materials. Ideal applications include hatches, doors, countertops, consoles, frames and trim, grab rails, rod holders, leaning posts, bow pulpits, furniture, and virtually any structural or decorative boat component. Its 1/2-inch thickness offers excellent rigidity for load-bearing and structural applications.
