Offering homeowners and designers alike a new design material crafted with the most realistic timber grain that replicates the elegance of exotic hardtimber, all backed by a 50-year warranty.

Best: Trex Transcend® Lineage™ and Trex Transcend® Decking

These decking lines offer the broadest range of decking colours and finishes.

Plus, Trex Transcend Lineage uses heat-mitigating technology that makes it our coolest decking yet.*

*Although Trex Transcend Lineage is designed to be cooler than most other composite decking products of a similar colour, on a hot sunny day, it will get hot. On hot days, care should be taken to avoid extended contact between exposed skin and the deck surface, especially with young children and those with special needs.

Better: Trex Select® Decking

A 35-year warranty backs our Trex Select decking line. The fade and stain protection, as well as enhanced mould and mildew resistance, make maintenance simple.

These decking lines should not be combined to avoid tripping hazards.
