Application of Galvanized Coil

1. Introduction of galvanized coil

Galvanized coils are made from hot rolled stainless steel coil. During cold rolling, the rolling temperature of the rolling stock is lower than the recrystallization temperature. Generally, steel parts are rolled at room temperature. High silicon steel sheets are brittle and low in plasticity. Since the cold-rolled coil is not heated in the production process, there is no pitting corrosion, iron oxide scale and other defects in the hot-rolling process, and the surface quality is good and the finish is high. In addition, the dimensional accuracy of cold-rolled products is high, and the performance and structure of the products can meet some special application requirements, such as electromagnetic properties, deep drawing properties, etc.

The corrosion resistance of hot-dip galvanized sheet comes from the standard potential of zinc and the standard electrode potential of iron. Therefore, the service life of the iron and steel process is greatly extended by the cathodic protection of the zinc layer and the maintenance of the steel substrate in water or wet and cold gas. Hot-dip galvanizing, phosphating, hot-dip galvanizing by thermal spraying, and hot-dip galvanizing for mechanical equipment are common types of hot-dip galvanizing in industrialization, of which hot-dip galvanizing accounts for about 80%.

2. What are the applications of galvanized coils?

Galvanized coil has good quality, long service life and wide application. Galvanized steel is used in many fields and plays an important role in our industrial production. Galvanized steel also has good corrosion and fire resistance. When used in industrial production, it can improve product quality. It is strong and can withstand a lot of tension. Therefore, it has been widely used. Strip steel provides a lot of convenience for our life and is an indispensable raw material in our industrial production. Galvanized steel can produce a variety of products that benefit our lives.

At this stage, many manufacturing industries use galvanized coil raw material. The vast majority of raw materials are used in trolley manufacturing, storage boxes, public machinery, construction and furniture. Hot-dip galvanizing is a popular anti-corrosion method at present. First of all, it can not only coat a layer of original film on the surface of stainless steel plate, but also maintain long-term anti-corrosion effect even if the original film has damaged areas, and comprehensively improve the service life.

Galvanized coils are highly flexible. Although the application fields of galvanized coil sheet are different in the sales market, the goods can be bent 180 degrees during the whole application process, and the outer zinc layer will not fall off. In this case, the performance of the application is very good. Only by mastering the mechanical properties of the product can we make better choices, display the mechanical properties of the product, and make the application performance more obvious.
