Co-Extrusion WPC Decking 140x22 Waterproof Outdoor Board

What is Co-Extrusion WPC Decking?

Co-extrusion WPC decking is an advanced second-generation wood plastic composite product manufactured through a co-extrusion process, where multiple layers of material are extruded and bonded into a single structural board.

The outer protective layer is made of high-performance polymer, which significantly enhances resistance to moisture, stains, UV exposure, and daily wear. Compared with traditional WPC decking, co-extrusion decking offers longer service life and easier maintenance, making it ideal for high-traffic outdoor environments.

Installation Guidelines

Proper installation ensures long-term performance and stability of WPC decking systems.

• WPC materials have slight thermal expansion and contraction, so proper spacing must be left between boards and ends to avoid stress deformation.

• Installation is recommended on a joist (keel) structure for better stability.

• Recommended joist spacing: 30–45 cm, depending on board thickness (20–40 mm range).

• Installation gaps should be adjusted according to local climate and temperature conditions.
