The grad® system features aluminum profiles (also known as rails) with pre-installed grad® clips.
The grad® clips are not made from ordinary plastic, but from Polyoxymethylene (POM), a high-performance thermoplastic commonly used in the manufacture of snow skis. POM is highly favored in various sectors of the construction industry and is recyclable.
The rails need to be securely fixed to the main structural elements (such as beams, joists, or concrete floors). The type and number of required accessories depend on the substrate material and wind zone. Please refer to our installation guide for more detailed instructions.
The rails must be installed parallel to one another (using a leveling tool) and the clips must be aligned from one rail to the next. There is no need to use a rail for each individual panel! The number of rails required is similar to the number of 2×4 beams you typically use in traditional installations.
Why are the clips pre-installed on the aluminum groove? What does this mean?
In traditional installation methods for outdoor decking, individual clips are placed every 40 cm (approximately 16 inches) along each plank to secure the floor.
With the grad® system, the clips are pre-installed in their correct positions, eliminating the need for additional individual clips. The planks simply snap into the clips, meaning there is no need to secure them with screws. The installation process is fast, easy, direct, and error-free.
The grad® clips are made from Polyoxymethylene (POM), a material known for its excellent dimensional stability, high mechanical strength and rigidity, corrosion resistance, and toughness at low temperatures (down to -40°C). It also offers resistance to moisture, gasoline, solvents, and many other neutral chemicals. This makes the grad® clips suitable for use across a wide temperature range (up to +90°C).
