Q&A

Does Trex Rocky Harbor Composite Decking 12ft Grooved look like real wood?
Yes. Trex Enhance Naturals boards feature multi-tonal grain patterns that closely mimic weathered coastal hardwood, offering realism without maintenance.

Can I use grooved boards for stairs?
No, Trex recommends solid-edge Rocky Harbor boards for stair treads and picture framing, as these areas require secure face fastening.

How does Rocky Harbor perform in Canadian weather?
