Whilst overhanging of composite decking boards is a popular choice, you run the risk, especially with hollow composite decking boards of reducing the board’s structural integrity possibly leading to snapping, breakage and potential accidents. Not only are the decking boards affected, but the frame as well. The exposed ends could absorb moisture, causing the decking boards to warp or increase mould growth. While composites are water-resistant, these end cuts are more exposed to the elements than normal.

For instance, Trex recommends a 102mm maximum allowable overhang for their decking boards.

Once testing is done, they can release information regarding their decking products. Some brands may use third-party inspectors for testing.
