The galvanized steel sheet: - Ensures the mechanical strength and unbreakability - Ensures a low thermal expansion
1700 microns of the anti-corrosion protective layers: - Galvanized steel completely envelop and protect it from oxidation - Muffle the plate, thus eliminating the noise problem in the rain and hail - Provide a thermal inertia
External metal sheets: - Dress in layers anticorrosion now their plasticity over time - Think, with natural aluminum finish, the sun’s rays.
