Resin Decking Composite Joist Expansion Screws For WPC Decking

Resin Decking Composite Joist Expansion Screws for WPC Decking are designed to pin down the joist to the sub floor. Once installed the screw will allow expansion and contraction of the joists. Use these screws to secure WPC joists directly to solid flat surfaces. The composite board can then be laid directly on top.

Do not use expansion screws to fix WPC joists over uneven ground. Consider instead, installing concrete hunching over the uneven ground when WPC joists are being installed.
