Co-extrusion Decking
Co-extrusion Decking (also known as co extrusion wpc decking) is the next-generation premium outdoor flooring material designed for high-end landscape and architectural projects. Compared with traditional WPC and solid wood decking, co extrusion decking adopts a dual-layer integrated extrusion system, combining a protective polymer shell with a structural wood-plastic composite core.
This advanced co extruded decking technology creates a fully sealed surface that eliminates common problems such as fading, cracking, mold growth, and surface peeling. As a result, co extrusion wpc decking delivers long-term durability, minimal maintenance, and superior aesthetic stability for outdoor environments.
Product Description
Co extrusion decking is manufactured through a dual-layer co-extrusion process:
Outer Layer: High-performance polymer protective cap (anti-UV, anti-stain, waterproof)
Inner Core: Wood plastic composite (HDPE + wood fiber + additives)
During production, both layers are extruded simultaneously under high temperature and pressure, forming a permanent molecular bond. This makes co extruded decking fully sealed, preventing water penetration and surface degradation.
Unlike traditional WPC boards, co extrusion wpc decking has no exposed wood fibers, which significantly improves resistance to weathering and staining.
Product Advantage
1. Dual-Layer Protection System
Co extrusion decking features a fully wrapped protective shell that isolates the core from UV rays, moisture, and oxygen. This ensures long-term structural stability and surface integrity.
2. Superior Color Stability
Thanks to advanced UV-resistant technology, co extruded decking maintains consistent color under long-term sunlight exposure. It resists fading, whitening, and patchy discoloration even in harsh climates.
3. Waterproof & Anti-Mold Performance
The sealed surface of co extrusion wpc decking prevents water absorption. It does not rot, swell, or develop mold, making it ideal for humid and coastal environments.
4. Zero Maintenance Requirement
Unlike traditional wood decking that requires painting or oiling, co extrusion decking only needs simple water cleaning. No sanding, no sealing, no repainting—significantly reducing long-term maintenance costs.
5. Slip-Resistant & Comfortable
The embossed wood grain surface provides excellent anti-slip performance in both dry and wet conditions. Co extruded decking ensures safe walking for families, children, and elderly users.
6. Eco-Friendly & Safe Material
Co extrusion wpc decking is manufactured using recyclable HDPE and natural wood fibers. It is formaldehyde-free, non-toxic, and compliant with international environmental standards.
7. High Structural Stability
The engineered core structure reduces thermal expansion and contraction. Co extrusion decking remains stable in extreme temperatures without warping, cracking, or deformation.
8. Easy Installation System
Designed with modular accessories, co extruded decking supports quick installation using clips, joists, and edge trims, significantly reducing construction time.
