Rooftop Decking System

Grad Concept USA has introduced the North American launch of its Grad Rooftop Decking System.

The thermoplastic polyolefin (TPO)-friendly system makes installation simpler, and up to 50% faster than conventional decking, while requiring fewer people to complete the job. Utilizing screw-adjustable pedestals, the waterproof 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.

The attachment components are virtually maintenance-free, offering maximum resistance to rot. The polypropylene pedestals, which meet ASTM D1929 and D635 standards, provide a stable, durable, and stiff infrastructure for attachment, while the polyoxymethylene fasteners (which are not exposed to direct UV light) offer strength and flexibility.

The decking system can also be used for poolside decking, is compatible with many different Grad-approved decking brands, including a wide range of natural wood and thermally modified wood species, bamboo, and aluminum options.
