The super-dense Korelite cell structure creates decking that’s lighter and stronger than other materials. Specialized engineering and manufacturing produces a timber with greater density at the top and bottom, much like an I-beam. In addition, the high-performance capstock and foam interior act as a stress skin panel. As a result, this proprietary design minimizes surface imperfections, voids and water absorption while offering superior strength and impact resistance, and a solid feel underfoot.
