The square-edge profile makes them ideal for exposed edges, traditional decking layouts, and easy alignment during installation. Supplied in 4.88m lengths, they’re manageable on site and perfect for both small DIY projects and larger commercial installations.

TJ’s Tip:
Leave a small expansion gap at the ends and sides to allow for seasonal movement, and clean regularly with soapy water and a soft brush. For a flawless, long-lasting finish, take your time aligning boards—your deck will look sharp for years.
