Corrosion Resistance 0.25 Thickness Galvalume Steel Coil Roofing Sheet
Galvalume is one of the most popular roofing materials in South-America and is a type of steel
roof coating made from aluminum, zinc, and silicon. Aluminum makes up more than 50% of the
coating, making it more resistant to corrosion.
A: 55% Aluminum inside the coating, make it bright, with strong corrosion resistance.
B: smooth, bright, and uniform, with a fine metallic luster and no visible spangles.
C: distinct, visible zinc crystal patterns with a textured metallic appearance.
