What Is Galvanized Steel?
Main Features
1) Corrosion resistance:When zinc is abraded, aluminum forms a dense layer of alumina that prevents further corrosion of the corrosive material inside.
2) Heat resistance:Aluminum zinc alloy steel has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius.
3) Thermal reflexes:The heat reflectivity of Al Zn steel plate is very high, which is two times that of galvanized steel sheet.
4) economical efficiency:Since the density of 55% AL-Zn is smaller than the density of Zn, the aluminum-zinc-plated steel sheet is more than 3% larger than the area of the plated steel sheet when the weight is the same and the thickness of the gold-plated layer is the same.

Advantage & Application of Galvanized Steel Sheet:
Corrosion Resistance: the zinc coating surface protects the base steel not only by providing barrier to corrosion elements,
but also by the sacrificial nature of the coating. Galvanized steel often remains in working order with little maintenance for
40 years or more.
Production Process:
The production process of hot-dip galvanized sheet:preparation of original board → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection. According to the habits, the hot-dip galvanizing process is divided into two categories: off-line annealing and in-line annealing.
Because of permanently and successive zinc/iron alloy layers, galvanized steel offers many benefits than traditional steels.

Packing:
The steel strips supplied according to the standard are usually applied with common rustproof oil film, which can be swept away with alkali solution. The supplier guarantees that the oiled products will be free from rust under normal packing, transportation, loading and storage conditions within 6 Months, the approved delivery date. However, product without oil coating can also be subject subject to statement in the contract reached after discussion between the user and the supplier.
We offer different modes of transport depending on the customer's destination: rail transport and ship transport.The Shipping Mark shall consist of: Trade mark, Seller's name, Product name, Applicable standards, Specifications, Package No., Contract No., Heat No., Weight of zinc film, Color, Production date, Weighing method, Net weight, Gross Weight, Consignee and Protection symbols, etc.
