Processing instruction
The pre-painted aluminum strip can be processed by cutting, stamping, milling, etc., and can also be bent to form. For fear of the aluminum surface coating damage during processing and installation, a white, UV-protective film can be attached to surface. In order to avoid cracking of the board base during processing, the minimum inner bending radius(2.5T DIN5520) and minimum processing temperature(20°c) should be strictly followed.
Aluminum metal roofing installation instruction
In order to ensure the consistency of color and gloss, the aluminum materials produced in the same batch should be installed in the same direction.
Metallic paint plates must be installed in the same direction, and ordinary paint products are also recommended to be installed in the same direction.
The product mark is printed on the protective film, and the arrow represents the direction of painting.
