The development history of Galvanised steel.

Galvanisation is a common technique in modern industry, which is the process of applying a thin layer of other metals or alloys to the surface of certain metals using the principle of electrolysis, which is the process of applying a metal film to the surface of a metal or other material to prevent it from oxidising. The product we are introducing today is related to metal plating and is called Galvanised steel, and this article will provide basic information on Galvanised steel, such as the history of Galvanised steel.

The development history of galvanised steel.

Why was galvanised steel developed?

After the 1920s, the rapid development of the automotive, machinery, electronics, household hardware and household appliances industries and the need for new technologies greatly accelerated the research, development and promotion of new plating technologies.

How did galvanised steel develop?

The first continuous hot-dip galvanised steel production line was established in the USA in 1937 and the first continuous electro-galvanised steel production line was built in the USA in 1942. Up to now, hot-dip galvanised products are widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industry, etc., in almost every field of clothing, food, housing and transport. It is no exaggeration to say that Galvalume steel is an essential material in modern industry.

The purpose of the development of galvanised steel

In the beginning, the purest purpose of galvanising was simply to prevent corrosion of the steel, the thickness of the coating being positively correlated with the protective properties. However, as galvanising technology continues to improve and develop, the direction of galvalume steel strip is changing and becoming increasingly decorative.

Advantages of Galvalume steel.

The advantages of galvanised steel are numerous. It has a beautiful appearance, high corrosion or wear resistance, high hardness, reflectivity, electrical conductivity, magnetic properties, weldability, etc. Since its introduction it has been used in a wide range of industries such as construction and household appliances. As time goes by, galvanised steel is being used in more and more applications.

Classification of Galvalume steel

Hot-dip galvanised steel

Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanised steel pipe substrate reacts with the molten plating solution in a complex physical and chemical reaction to form a corrosion-resistant, structurally compact zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore, its corrosion resistance is strong.

Cold Galvanised

Cold galvanised can be considered to be electro-galvanised, and the amount of galvanisation is very small, and its own corrosion resistance is much worse than that of hot-dip galvanised pipes. Most of the regular galvanized pipe manufacturers do not use galvanizing in order to ensure quality.
