King StarBoard ST is a unique and advanced high-density polyethylene construction sheet that lasts a lifetime. The polymer sheet is 25% stiffer than the original King StarBoard. King StarBoard ST features a matte gloss finish on both sides of the sheet. It is environmentally stabilized to withstand the harshest outdoor conditions. King StarBoard ST won't rust, delaminate, or rot when exposed to UV rays, moisture, or water. It is one of our most scratch-resistant polymers, making it an excellent construction material for cabinetry, furniture, and architectural partitions. The polymer sheet never needs to be painted or refinished, works like wood, and is easy to fabricate with standard woodworking tools and techniques.
