King StarBoard® XL is a lightweight, marine-grade, cellular high-density polyethylene sheet that is up to 30% lighter than the original King StarBoard®. It is the product of a proprietary process called K-Stran™, the most advanced manufacturing process for superior flatness and consistency. King StarBoard® XL has a matte finish on both sides of the sheet. It is environmentally stabilized to withstand the harshest outdoor conditions. King StarBoard® XL will not rust, delaminate or rot when exposed to UV, humidity or water. It is ideal for a variety of marine applications from boat components to equipment mounts, and looks good enough to use in high-visibility applications where structural strength and a finished edge are not important. For maximum versatility, standard colors are made to coordinate with the original King StarBoard®. The polymer sheet never needs painting or refinishing, works like wood, and is easy to fabricate with common woodworking tools and techniques.
King StarBoard XL is upgradable to King MicroShield® with an advanced antimicrobial technology for protecting the product surface against stain and odor causing bacteria, algae and fungi.*
