Aluzinc Steel Coil
Overview of Aluzinc Steel Coil
Also known as galvalume or zincalume steel, aluzinc steel is a form of cold rolled galvanized steel with metal coating composed of 55% aluminum, 43% zinc, and 1.6% silicon. Its unique composition gives aluzinc steel some distinctive features by the combination of the physical protection and high durability of aluminum and the electrochemical protection of zinc.
Features of Aluzinc Steel Coil
Superior long term corrosion resistance allows aluzinc steel coils to outperform galvanized coating by 2 to 6 times
The density of 55% aluminum is smaller than that of zinc. With the same weight and thickness of the plating layer, the area of the galvalume steel sheet is 3% or larger than that of a galvanized steel sheet.
