Main characteristics
Corrosion resistance: Aluminized zinc coil has strong corrosion resistance, and its normal service life can reach 25 years, which is 3-6 times longer than galvanized sheet. And it is comparable to stainless steel. This corrosion resistance is mainly derived from the barrier protection function of aluminum and the sacrificial protection function of zinc. When the zinc layer is damaged, the aluminum forms a dense layer of alumina that prevents further corrosion.
Heat resistance: It has good heat resistance and can withstand high temperature environments up to 315 ° C. It is very suitable for use as a roofing material and in high temperature environments.
Thermal reflectivity: The alloy steel coil has a very high thermal reflectivity, twice that of galvanized steel, and is suitable as a thermal insulation material.
Good processing performance: it can be stamping, cutting, welding and other processing methods. The coating has good adhesion and impact resistance.
Electrical conductivity: The specially coated steel plate surface can meet the needs of electromagnetic shielding.
Economy: Due to its lower density, this steel coil has a larger area than the plated steel coil for the same weight and coating thickness, reducing the cost.
Production Process of Aluminized Zinc Coil
The production process of Aluminized zinc coil mainly includes the uncoiling process stage, the coating process stage and the winding process stage:
Uncoiling process stage: the steel coil is lifted to the production line by the crane, and is ready to enter the coating process stage after uncoiling, shear welding, cleaning, drying and other processes.
Coating process stage: the strip steel enters the continuous annealing furnace for heat treatment after correction and tension adjustment. It then goes into the zinc pan to be coated. Excess zinc liquid is blown away by air knife to ensure uniform coating thickness. Then air cooling and water quenching cooling. The worker then performs finishing, stretching and passivation. This improves the coating performance.
Winding process stage: After a series of treatments, the strip steel enters the winding stage, for oiling, winding, splitting and other procedures. Final packaging or proceed to the next process.
