The GRAD System is a significant advantage for designers and contractors today, offering an aesthetically pleasing appearance and fast, easy installation. The aluminum rail, featuring a hidden clip system, is used for decking, siding, and more. It is made from 80% recycled aluminum and is lightweight, corrosion-resistant, and non-flammable. The plastic clips keep their natural elasticity over time.
GRAD System clips come pre-fixed and do not require individual fastening. There’s no need to double-check board spacing, saving up to 50% of install time.

Decking and open joint cladding boards can be easily removed and updated using a dismantling tool, ensuring no damage in the process.
Clip spans are tailored to your project, offering a unique solution and can accommodate board widths, variable spacing, 3D effects, mixed materials, and more.
GRAD materials are resistant to corrosion, fire, insects, and rot, and can be used in a wide range of temperatures and climates.
Because the boards sit on clips, there’s no contact with the aluminum joists — reducing water traps and helping prevent cupping for longer-lasting performance.
The aluminum frame, clips — made from polyoxymethylene — and accessories work together to create a stiff, highly stable structure.
Perfectly aligned boards ensure clear drip lines and uniformity that complements any design.
