This 148.5*22.5mm WPC decking board innovatively combines a 7-round-hole framework with a full co-extrusion capping process, engineered specifically to withstand extreme outdoor climates. The 7-hole structure not only provides excellent bending toughness but also efficiently absorbs external impacts, ensuring the deck remains deformation-free under long-term foot traffic. Its true core highlight lies in the polymer co-extruded protective layer. This 360° dense armor completely isolates the WPC core from the outside world, fundamentally preventing moisture penetration and UV erosion. Even on high-salinity coastal boardwalks or sun-baked poolside areas, it guarantees no fading or molding. With minimal maintenance costs, it offers a versatile paving solution that combines long-lasting weather resistance with 3D wood grain aesthetics for high-end projects.

Specifications
Co-extrusion decking (also known in the trade as "capped" decking) is the premium tier of WPC outdoor decking. A conventional WPC board is a single material extruded through and through — the board is only as good as the material.

Composite Decking
Description
A co-extruded board, by contrast, is built as two layers in one: as the core is extruded, a dense engineering-polymer cap is co-extruded onto its outer face simultaneously, fusing core and shell into one piece on the same production line — a bond that will never delaminate, peel or bubble.


Co-extrusion decking
Colour that lasts: a dense polymer cap is co-extruded and fused onto the core in-line — powerful UV stabilisers keep the shade true for years of full sun
The fully-wrapped core shuts out moisture and mould at the root.

Composite Decking
Specifications
Composite decking retains the essence of natural wood while eliminating its downsides. It's constructed from a combination of wood fibers, recyclable plastic, and binder. As a result, composite decking has the rich beauty of wood but without the upkeep requirements. Capped composite decking allows you to enjoy the classic appearance of wood without the risk of warping or splintering.

Color
Composite decking provides limitless options for building outdoor living spaces. It comes in a variety of colors, finishes, and textures, allowing you to design a deck that compliments the architecture and personal style of your home. From classic warm wood tones to trendy greys and sleek blacks, the choice is greater than you might expect.








Composite Decking
Inspiration
The composite decking is specifically engineered to endure the elements. It is long-lasting and resistant to the wear and tear that can occur with standard wood decking, regardless of whether it is hot in the summer, pouring rain, or frigid in the winter. With capped composite decking, you can say goodbye to rust, decay, and insect damage.
