WPC Joists – The "Invisible Backbone" of Outdoor Decking Systems

As the core supporting structure for decks, balconies, and poolside decking, traditional wooden joists suffer from rot, deformation, and frequent maintenance, while metal joists are prone to rust and noise. Our WPC Joists, crafted from innovative composite materials, provide a long-lasting, stable foundation for your flooring systems.

✅ Weather & Corrosion Resistant

Made from a premium blend of wood flour and high-grade polymer, our WPC Joists offer exceptional water, moisture, and corrosion resistance. They remain structurally stable in harsh environments such as humidity and salinity, with a lifespan 3–5 times longer than traditional wooden joists. They resist shrinkage and cracking even in extreme temperatures (-40℃ to 60℃).

✅ High Load-Bearing & Anti-Deformation

Optimized profile design balances rigidity and toughness, with a single joist capable of supporting ≥200kg/m² uniform load. It resists bending and sinking over long-term use, providing a solid, reliable base for upper flooring.

✅ Easy Installation & Efficient Construction

Lightweight design allows direct fixing with expansion screws, no additional connectors needed. It can be laid directly on concrete bases, steel structures, or elevated brackets, significantly reducing project time and labor costs.

✅ Eco-Friendly & Sustainable

Made from recycled wood flour and plastic, our WPC Joists release zero formaldehyde during production. They reduce deforestation and plastic waste, complying with green building material standards.
