King StarBoard® is the original marine-grade high-density polyethylene sheet and the leading brand in the marine industry. The King name is synonymous with quality to those who know plastics, and the King StarBoard® brand has been helping pros build better boats for more than thirty-years. It is the product of a proprietary process called K-Stran™, the most advanced manufacturing process for superior flatness and consistency. King StarBoard® has a matte finish on both sides of the sheet. It is environmentally stabilized to withstand the harshest outdoor conditions. King StarBoard® will not rust, delaminate or rot when exposed to UV, humidity or water. It is ideal for a variety of marine applications from replacing wood, to building boat components and furniture. The polymer sheet never needs painting or refinishing, works like wood, and is easy to fabricate with common woodworking tools and techniques.

King StarBoard® is upgradable to King MicroShield® with an advanced antimicrobial technology for protecting the product surface against stain and odor causing bacteria, algae and fungi.*

King StarBoard® is upgradable with King FlameShield, for ASTM E-84 Class A Flame Compliance and CAN/ULC-S102 for Canadian Compliance.
