The development history of galvanized steel sheet

The first continuous hot-dip galvanized strip production line was established in the United States in 1937, and the first continuous electro-galvanized strip production line was built in the United States in 1942. It has been in industrial production for more than 70 years.

Prepainted Galvanized Steel Coil
Hot-dip galvanized products are widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industries, etc., involving almost all fields of clothing, food, housing and transportation. In recent years, the world's demand for galvanized steel has been increasing, and the output has also grown rapidly. In the United States, Japan and other major steel producing countries, the proportion of hot-dip galvanized steel in steel has reached as high as 13%-15%.
Recently, the automotive industry has paid more and more attention to the service life of materials, and painted cold-rolled steel sheets can no longer meet the requirements of corrosion resistance. Under this circumstance, hot-dip galvanized sheet with excellent corrosion resistance and low cost is generally favored by automobile manufacturers.
The biggest advantage of coated steel sheet is excellent corrosion resistance, paintability, decoration and good formability.

Advantages and disadvantages of hot rolled steel

By definition, steel ingots or billets are difficult to deform at room temperature and difficult to process. Generally, they are heated to 1100-1250 °C for rolling.

Characteristics and uses of hot rolled steel coils

Hot-rolled coils are made from slabs (mainly continuous casting slabs). The hot steel strip coming out of the final rolling mill of finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel strip coil by a coiler.

Types and uses of hot rolled steel sheets

Hot continuous rolled steel sheet products include steel strips (coils) and steel sheets cut from them. The steel strip (roll) can be divided into straight hair rolls and finishing rolls (split rolls, flat rolls and slit rolls).
