Co-extruded WPC decking combines wood-plastic composite core with tough polymer outer layer, enhancing durability. The co-extrusion process creates a waterproof, UV-resistant surface that prevents fading, cracking, and mold growth. Unlike traditional wood, it won’t splinter, warp, or rot, making it ideal for harsh weather. The textured finish improves slip resistance, while the low-maintenance design requires no staining or sealing. With a lifespan of 20+ years, it’s a cost-effective, long-lasting solution for decks, balconies, and pool areas etc.

The Co-extruded outer shell is engineered with high-performance polymers blended with UV stabilizers, color pigments, and wear-resistant additives. This 360 degrees protective surface enhances the decking’s durability, weather resistance, and visual appeal, while effectively preventing moisture absorption, fading, and surface damage.
The core is made from wood fibers and high-density polyethylene (HDPE). This advanced core material offers excellent structural strength and dimensional stability, along with superior resistance to rot, insects, and decay — making it an ideal choice for long-lasting, low-maintenance outdoor decking.
Co-extruded WPC decking provides a versatile, low-maintenance solution for a variety of outdoor environments. Due to its resistance to stains, fading, and moisture, key applications include residential patios, courtyards, and pool surrounds. It is also well suited for commercial spaces such as restaurants, hotels, and boardwalks, as well as public infrastructure such as parks and piers, where durability, safety (anti-splintering), and aesthetics are important.
