Galvalumed stee is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at 600℃.
Galvalumed has many excellent characteristics: strong corrosion resistance, is pure galvanized sheet 3 times;There are beautiful zinc flower on the surface, which can be used as building outdoor board.
Corrosion resistance
“Galvalumed steel coil” corrosion resistance is mainly because of aluminum, aluminum protection function.When zinc wears down, aluminum forms a dense layer of alumina, preventing the corrosion-resistant material from further corroding the interior.
Heat resistance
Galvalumed steel plate has a good heat resistance, can withstand more than 300 degrees Celsius of high temperature, and the high temperature oxidation resistance of aluminum plate is very similar, often used in
Chimneys, ovens, illuminators and lampshades.
Heat reflective
Galvalumed has a high thermal reflectivity, which is twice as high as galvanized steel. It is often used as an insulating material.
Economy
Since the density of 55% al-zn is lower than that of Zn, the area of Galvalumed steel plate is more than 3% larger than that of galvanized steel plate at the same weight and the same thickness of the gold-plating layer.
