King Plastic KSXWHWHMM.50024.060.00 StarBoard XL 1/2" x 24" x 60" White/White Marine HDPE Sheet

King StarBoard® XL is a lightweight, marine-grade cellular high-density polyethylene (HDPE) sheet measuring 1/2" thick x 24" wide x 60" long in a White/White finish. Manufactured using King Plastic's proprietary K-Stran™ process, this sheet delivers superior flatness and consistency while weighing up to 30% less than standard King StarBoard®.

King StarBoard® XL is 100% virgin polymer marine-grade cellular material with an excellent surface finish, making it suitable for high-visibility applications where structural strength and a finished edge are not critical. The matte-textured finish on both sides gives it a clean, professional appearance that coordinates perfectly with the original King StarBoard® product line.

• Up to 30% lighter than standard King StarBoard® — ideal for weight-sensitive builds
• Marine-grade cellular HDPE construction via proprietary K-Stran™ manufacturing process
• Matte finish on both sides — matches original King StarBoard® textures and colors
