The King StarBoard 1/4" x 24" x 54" Black Sheet is the original marine-grade high-density polyethylene (HDPE) building sheet and the industry standard for boat builders and marine fabricators worldwide. Manufactured by King Plastic Corporation using the proprietary K-Stran™ process, this sheet delivers exceptional flatness and consistency across every panel.

• Matte Finish on Both Sides: Dual-sided matte surface helps hide scuffs and scratches for a consistently clean appearance
• Easy to Fabricate: Works with standard woodworking tools and techniques — no special equipment required
• Low Maintenance: Requires no painting, sealing, or refinishing; cleans easily and resists staining
• Sheet Dimensions: 1/4" thick x 24" wide x 54" long (approximately 9 sq. ft.)
• Color: Black
• Thickness Tolerance: ±5% on gauge; length and width plus only at room temperature

King StarBoard is trusted by OEM boat builders and DIY marine enthusiasts alike for applications such as hatches, doors, storage units, swim platforms, fish-cleaning tables, handrails, steps, and dinghy chocks. It is the preferred replacement for wood components where long-term durability and zero maintenance are required.
