Aluminum sheets can be flat or stucco embossed. Aluminum has a high corrosion resistance, high conductivity and a much higher elongation coefficient than galvanized steel.
It is a preferred material to use in acidiferous environments or heavy industrial areas. It can be used raw, lacquered or painted. The aluminum sheet thickness at load-bearing layers of insulated panels and trapezoidal sheets should not be less than 0,70mm.
