WPC Decking Frame Joist

When building your WPC deck we believe that its important that the frame your WPC decking boards are fastened to is as long lasting & strong as the decking boards themselves. This 3.6 metre WPC / Composite decking joist is the ideal decking frame solution'

  • Profile size: 40mm x 30mm x 3600mm
  • Wood polymer composite material
  • Stronger than timber and will not rot
WPC Decking Frame Joist

£12.80 / 3.6m Assisted

We see many people using traditional wood for deck framing due to a perceived cost saving & then lay WPC / composite decking boards on top. This is a false economy as the WPC decking boards will outlive the wooden frame which will suffer from rot & warping long before the guaranteed life of our WPC composite decking boards expires.

Our advice is to ALWAYS use WPC Composite Joists for a long lasting / low maintenance deck.
