King ColorBoard® is a colorful environmentally stabilized high-density polyethylene sheet. It is the product of a proprietary process called K-Stran™, the most advanced manufacturing process for superior flatness and consistency. King ColorBoard® has a matte finish on both sides of sheet. It is environmentally stabilized to withstand the harshest outdoor conditions. King ColorBoard® will not rust, delaminate or rot when exposed to UV, humidity or water. The material is versatile, durable and colorfast for the competitive edge you’re looking for. Its bright, primary colors make it ideal for sign, industrial, marine, playground and recreational applications. For maximum versatility, standard colors are made to coordinate with King ColorCore®. The polymer sheet never needs painting or refinishing, works like wood and it is easy to fabricate using common woodworking tools and techniques.

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