Duofuse Composite Decking Support Beam 50 x 60mm x 4m
The Duofuse Support Beam is a key component of the Duofuse composite decking system, providing a durable base for fixing Duofuse WPC decking boards. Measuring 50mm x 60mm x 4 metres, this black support beam is designed to provide a stable and reliable foundation for decking installations.
Manufactured as part of the complete Duofuse decking system, the support beam works with the specially designed decking clips to provide an invisible fixing system, eliminating visible screws and nails from the finished decking surface.

Duofuse Composite Decking System
Duofuse composite decking combines the natural appearance of timber with the durability and low-maintenance benefits of wood plastic composite. The complete system includes decking boards, support beams, adjustable beams, skirting, profiles and clips.
Duofuse decking is designed to resist rotting, swelling, splintering and splitting, providing a long-lasting solution for terraces and outdoor areas when correctly installed.
Installation Options
The Duofuse support beam can be installed in two positions, allowing the decking surface to be positioned approximately 35mm or 48.5mm above ground level, depending on the installation method.
For higher installations, including roof terraces, polypropylene pedestals can be used to achieve greater heights. Where pedestals are used, the wood composite support beam should not be used as a structural element.
