In the UK, traditional “tanalised” timber is not as reliable as it once was. Ground-contact rot is the leading cause of failure in outdoor projects. By switching to a composite subframe, you will receive a structural guarantee that matches the lifespan of their premium decking boards. This professional upgrade justifies a higher project price and eliminates the risk of the frame collapsing long before the decking boards wear out.
Our subframes UK range is designed to withstand the harshest British weather conditions. Unlike wood, which expands and contracts and can lead to “screw pull” and squeaky boards, composite materials are incredibly stable.
