The Grad Rooftop Decking System from Grad Concept makes installation simpler, easier and up to 50% faster than conventional decking, while requiring fewer people to do the job.
Utilizing screw-adjustable pedestals, the waterproof thermoplastic polyolefin system raises the deck floor off the TPO as high as 15”. The subdeck remains easily accessible, since boards can be individually removed no matter where they are located.
It comes with clips that are already pre-fastened into place and cannot be moved. When specially profiled boards are snapped onto the clips, they are straight with even gaps, eliminating the need for control checks. Boards can be removed, replaced and updated.
