King Plastic StarBoard Marine HDPE Sheet

King StarBoard Marine HDPE sheet is a high-density polyethylene (HDPE) panel stock made by King Plastic Corporation for boat building, marine fabrication, and general repair work. It is also known as marine polymer sheet or marine-grade plastic lumber. It is used in place of wood, fiberglass, and metal in places where moisture is a constant problem.

Key Features:

• Made from high-density polyethylene that does not rot, warp, or absorb water
• Resists many chemicals and withstands exposure to salt water and fresh water
• Does not need to be painted or sealed
• Can be cut, routed, drilled, and fastened with standard woodworking tools
• The material is the same all the way through, so scratches and scuffs do not expose a different core
• Suited to marine, RV, powersports, and general fabrication projects

Typical applications include hatches, dash panels, battery boxes, cutting boards, trim panels, and other custom parts. It gives builders and owners a durable, low-maintenance surface for use on or near the water. Sheets are available in several sizes and color combinations.
