Substructure and Accessories

What sub-construction materials are recommended for RAINBODECK?

• RAINBODECK recommends aluminum alloy, galvanized steel, or weatherproof treated wood as sub-construction materials.

• Composite/plastic materials are not recommended. Some brands promote composite/plastic joists for decking, ceiling, and wall cladding applications, claiming they are rigid, high-density materials. These claims are misleading. Composites are poor structural materials due to their pre-treated wood fiber content, which reduces screw-holding capacity and increases brittleness compared to natural wood. Plastic shares similar disadvantages.
  

• Untreated wood is not recommended as it rots easily and may cause structural issues.

Does RAINBODECK provide sub-construction materials?

• To provide complete solutions for our clients, RAINBODECK has developed an innovative range of aluminum alloy joists. Consult an RBD representative for more information.

Why does RAINBODECK only offer aluminium alloy joists?

• Aluminum joists offer significantly higher load capacity than composite, plastic, or wood joists. They are also lighter in weight while maintaining excellent screw-holding capability

• Compared to wood, aluminum provides superior strength and dimensional stability, ensuring a perfectly flat surface for decking materials. Wood joists often have inconsistent dimensions and may warp or twist over time, which can negatively affect the installed materials. Simply put, high-performance decking requires an equally high-performance substructure.
