King Plastic KSBBLAKMM.50054.096.00 King StarBoard 54in x 96in x 1/2in Black HDPE Marine Sheet

King StarBoard® is the original marine-grade high-density polyethylene (HDPE) building sheet and the leading brand in the marine industry. This full-size 54" x 96" x 1/2" black sheet is produced using King Plastic's proprietary K-Stran™ manufacturing process, delivering superior flatness, consistent thickness, and uniform color throughout the sheet.

Built to outlast wood in the harshest marine environments, King StarBoard® will not rot, warp, rust, splinter, or delaminate when exposed to UV radiation, humidity, or water. The dual-sided matte finish provides a clean, professional look while helping to conceal minor scuffs and scratches. Unlike teak and other traditional marine woods, this HDPE sheet requires no painting, sealing, or refinishing — ever.
