Product Description
Alu-zinc steel coil is based on cold-rolled steel sheet, which is solidified at 600℃ with 55% aluminum, 43.4% zinc, and 1.6% silicon. It combines the physical protection and high durability of aluminum with the electrochemical protection of zinc. It is also called galvanized steel coil.
The production process of galvanized steel coil is as follows:
Uncoiling-cleaning-annealing-zinc pot-cooling-air knife-straightening-post-processing-coiling
Heat reflection
People use it as a heat insulation material, and its heat reflectivity is up to twice that of galvanized steel sheet.
Heat resistance
Alu-zinc steel coil has good heat resistance and can withstand high temperatures above 300℃, which is very similar to the oxidation resistance of aluminum-coated steel sheet at high temperatures. It is often used in chimney pipes, ovens, luminaires, fluorescent lampshades, etc.
Corrosion resistance
The key to the corrosion resistance of galvanized steel coil lies in the protective properties of aluminum. Once the zinc is worn, the aluminum forms a dense layer of aluminum oxide to prevent further corrosion inside.
Economical
The density of 55%AL-Zn is lower than that of Zn, so the area of Al-Zn steel sheet is 3% larger than that of galvanized steel sheet when the coating weight and thickness are the same.
Easy to paint
The coating material on Al-Zn steel sheet has excellent adhesion and can be directly tarred on advertising boards and common sheets without pretreatment such as weathering.
