Corrosion Resistance Galvalume Steel Gl Steel Coil Cold Rolled Hot Rolled
Galvalume Steel (GL) Coil
Product details
Galvalume steel (GL) coil is cold rolled or hot rolled steel plate made of zinc as matrix and aluminum as surface coating on zinc surface.
Galvalume steel (GL) coil is an aluminum-zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at 600℃. The whole structure is an alloy of aluminum-iron-silica-zinc to form a dense quaternary junction crystal.
Galvalume steel (GL) coil has many excellent features:
Corrosion resistance: The corrosion resistance of Galvalume steel (GL) coil is mainly due to the protective function of aluminum. When the zinc is worn, the aluminum forms a dense layer of alumina, preventing the corrosion resistance from further corroding the interior.
Thermal reflectivity: Galvalume steel (GL) coil has a high thermal reflectivity, twice that of galvanized steel, and people often use it as a thermal insulation material. Such as car mufflers, household appliances, etc.
Heat resistance: Galvalume steel (GL) coil has good heat resistance, can withstand the high temperature of more than 300 degrees Celsius, and the high temperature oxidation resistance of aluminized steel plate is very similar, often used in chimney tubes, ovens, illuminators and daylight lampshades.
Economy: Because the density of 55%AL-Zn is less than that of Zn, the area of Galvalume steel (GL) coil is more than 3% larger than that of the coated steel coil under the same weight and the same thickness of the gold plating layer.
In addition, Galvalume steel (GL) coil also has the characteristics of high aesthetics, environmental protection, energy saving and consumption reduction.
