Galvanized coil is the abbreviation of ordinary carbon structural steel cold-rolled plate, also known as cold-rolled plate, commonly known as cold plate. Cold plate is made of ordinary carbon structural steel hot-rolled steel strip, which is further cold-rolled into a steel plate with a thickness of less than 4mm.

Since rolling at room temperature does not produce iron oxide scale, the cold plate has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process performance are better than hot-rolled thin steel plates. In many fields, especially In the field of home appliance manufacturing, it has gradually been used to replace hot-rolled thin steel plates.

1. Construction industry

In the construction industry, galvanized steel is mainly used to make building structures, roof panels, and wall panels. First of all, galvanized steel has strong corrosion resistance and can effectively prevent buildings from being affected by oxidation, corrosion, and pollutants.

Secondly, galvanized steel also has good plasticity and weldability, and can be processed and connected according to architectural design needs. In addition, in the event of a fire, galvanized steel can also play a fire isolation role to ensure the safety of the building.

2. Automobile manufacturing industry

In the automobile manufacturing industry, galvanized steel is mainly used for automobile casings, chassis and parts. First of all, in the automobile manufacturing process, galvanized steel can effectively improve the corrosion resistance of parts and extend the service life of the automobile.

Secondly, galvanized steel has high strength and toughness, which can improve the safety performance of cars. In addition, galvanized steel also has good plasticity and weldability, making it easy to manufacture auto parts of various shapes and sizes.

3. Home appliance industry

In the home appliance industry, galvanized steel is mainly used to make home appliance casings, internal structures and parts. First of all, during the manufacturing process of home appliances, galvanized steel can effectively prevent the electrical appliances from being affected by moisture, oxidation and corrosion, ensuring the normal operation of the electrical appliances.

Secondly, galvanized steel has good electrical conductivity and magnetic permeability, which can improve the working efficiency of electrical appliances. In addition, in the design of household appliances, galvanized steel can also be processed and painted as needed to make the product more beautiful.

It is widely used in construction, home appliances, automobile containers, transportation, etc. Besides, it has good coating adhesion and weldability. That's why it is also an ideal base metal for PPGI products.
