General information

The system consists of panels with 180 degree hems approximately 1" wide that interlock and are held on the substrate using cleats. The system allows a great deal of flexibility as flat lock panels can be made to many shapes and sizes. The panels can be square, diamond shaped and rectangular.

The panels are installed in a sequential order from bottom up. The panels are held in place using cleats which can be stainless steel, zinc or galvanized steel.

For larger panels galvanized steel cleats are recommended. The cleats should be fixed at a maximum of 12" centers.

For small diamond shaped panels the hems should be slightly notched thus allowing the cleat to sit securely. When installing large rectangular panels the short side should be fixed with a long fixing strip. It is recommended that screws be used to secure the cleats. The use of nails offers significantly less resistance.

The panels should be installed with the protective film in place. Protective film is recommended to be removed within 60 days post installation.
