Capped & 3D-Embossed Decking
Choose fully-capped co-extrusion boards for the toughest, longest-lasting finish, or 3D-embossed boards for a natural grain at a friendlier price. All boards are waterproof, splinter-free and fade-resistant.
Why SYAN WPC
Waterproof & Rot-Proof
Built for rain, snow and poolside damp. Won’t warp, splinter or rot.
Anti-UV Color Stability
The capped surface holds its color for years instead of greying out.
Anti-Slip Surface
Brushed or 3D-embossed finish — safe for wet and poolside areas.
~90% Recycled
Made from recycled wood fiber and HDPE — an eco alternative to timber.
Zero Maintenance
No staining, sealing or painting. Just rinse with soapy water.
10-Year Warranty
Backed in writing, with test reports on every shipment.
