Product Detail
Co-extrusion Capped technology. High-molecular dense protective layer fuses with solid core-high temp, high pressure. Wraps top, bottom, both sides. Completely. Moisture seeping from underneath? Eliminated. UV and stains attacking any surface? Resisted. Protection from inside out. Comprehensive. Total.

Customer FAQs
Q: "21mm solid-strong enough? Better than hollow?"
A: 140x21mm solid structure? Mechanically optimized. Bending strength? Far superior to hollow boards of same thickness. Load-bearing capacity? Same. Walk on it-feels stable. Solid. No hollow sound. No weird bounce. And solid structure eliminates hollow board problems: water accumulation inside, insect nests. Service life? Longer. Guaranteed.
Q: "Costs more than standard co-extruded. Worth investing?"
A: Think lifetime value. Four-sided coverage + solid structure = top WPC configuration. That means lifespan up to 25 years. Load-bearing capacity? Strongest. Environmental protection? Most comprehensive. Life-cycle cost? Much lower than any material needing maintenance or replacement. Commercial projects? High-end residential? Smart choice. Pays off long-term.
Our Advantages
Commercial-grade durability. Built for projects demanding high reliability, high load capacity. No compromises.
Maintenance? Nearly zero. Dense surface + solid core = no internal dirt, no water pooling, no insect infestation. Ever.
Stays flat. Always. Thermal expansion? Minimal. Water absorption? Minimal. Different climates, same consistent flatness.
Installation and Maintenance Instructions
-
Joists matter: Galvanized steel or aluminum. Spacing 30-35cm. Support stable. Ground level, with drainage slope.
-
Give it room: 8-10mm expansion gap at walls and fixed structures. Heat needs space.
-
Snap it hidden: Fully concealed stainless steel clips. Each board locked firm. No screws on surface. Clean look.
-
Finish edges: Special edge sealing strips. Steps, edges-refined. Complete.
-
Clean simple: Sweep leaves and gravel. Hose down. Stubborn spot? Neutral cleaner and soft brush. That's it.
