King StarBoard® AS is an anti-skid, marine-grade, 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 StarBoard® AS has a dot or diamond pattern on one side of the sheet and a matte finish on the other side. The special, high-friction anti-skid surface helps prevent slipping and promotes drainage. It is environmentally stabilized to withstand the harshest outdoor conditions. King StarBoard® AS will not rust, delaminate or rot when exposed to UV, humidity or water. It is ideal for a variety of high-traffic marine applications from decking and swim platforms to ladder steps where traction is critical. 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® AS is wrapped in a reusable plastic sheet during storage. The plastic wrap will be on skids containing light colors or a mix of light and dark colors and is not necessary on skids only containing Black or Charcoal Gray sheets. Please maintain the plastic wrap while the King StarBoard® AS sheets are in inventory as added protection and, whenever possible, the plastic wrap should be shipped to the end user, too. The skids will be identified with a blue end label as shown below. As a further precaution we advise storing King StarBoard® AS in well ventilated areas of warehouses and not in areas where exhaust from fossil fuel fired equipment can accumulate.
