Characteristics and application of galvanized steel coil

 Galvanized steel coil is a kind of steel product coated with zinc metal on the surface of steel plate, which has many excellent characteristics and wide application. The following is a detailed introduction to galvanized steel coil, including its characteristics, applications, specifications, production process and price information.

First, the characteristics of galvanized steel coil

1. Excellent anti-corrosion performance: the zinc layer on the surface of galvanized steel coil can effectively isolate the direct contact between the steel plate and the external environment, prevent the steel plate from being oxidized and corroded, thus extending the service life of the steel. Even under harsh environmental conditions, such as high humidity, salt, etc., it can maintain good anti-corrosion properties.

2. Easy processing: Galvanized steel coil has good processing performance, can be stamping, cutting, bending, drilling and other processing operations. The surface is smooth, the texture is uniform, and the problems such as burrs and rust are not easy to appear after processing, which reduces the trouble of post-processing.

3. Environmental protection and pollution-free: galvanized steel coil will not produce harmful substances in the production process, nor will it produce noise and waste. At the same time, the surface does not need coating treatment, avoiding the pollution of the paint to the environment.

4. High strength: high strength and hardness of galvanized steel coil, with good bearing capacity and seismic performance, suitable for a variety of structures requiring high strength support.

5. Economy: The production cost of galvanized steel coil is relatively low, and the service life is long, which can reduce maintenance and replacement costs. At the same time, its processing and installation is convenient, can improve the work efficiency, reduce the project cost.

Second, the application of galvanized steel coil

Galvanized steel coil is widely used in many fields because of its excellent properties, mainly including:

1. Construction field: used for components in building structures, such as beams, columns, purlins, etc. And building roof, wall and other parts to protect building materials from atmospheric and water corrosion.

2. Automobile industry: used in automobile manufacturing body, chassis, doors and other components to improve the safety and reliability of automobiles.

3. Home appliance industry: used in the production of refrigerators, washing machines, air conditioners and other home appliance products shell, improve the product beauty and durability.

4. Communication equipment: It is also used in the field of communication equipment, such as base stations, towers, antennas, etc., to ensure the stable operation of equipment.

5. Other fields: such as food processing, agricultural machinery, ship construction, furniture manufacturing, etc., galvanized steel coils play an important role.

Three, galvanized steel coil specifications

The specifications of galvanized steel coil mainly include thickness, width and material. In terms of thickness, the common specifications of galvanized steel coil are mainly concentrated between 0.18mm-0.3mm, of which 0.2mm is one of the more common and commonly used specifications. Different industries and uses also have different requirements for the width and material of galvanized steel coils.

Fourth, the production process of galvanized steel coil

The production process of galvanized steel coil mainly includes the following steps:

1. Steel coil pickling: Remove the oxide, oil and rust on the surface of the steel to ensure the galvanizing effect.

2. Cleaning: Rinse the residual acid, chloride ions and other harmful substances on the surface of the steel coil after pickling.

3. Pretreatment: A protective film is formed on the steel surface to increase the binding force between the steel coil and the zinc liquid and improve the quality of the coating.

4. Baking: the protective film on the surface of the steel coil is completely dry to facilitate the subsequent zinc dipping process.

5. Zinc dipping: Put the baked steel coil into the molten zinc solution for dipping and plating to form a zinc layer.

6. Cooling: the zinc layer on the surface of the steel coil quickly solidifies to ensure the quality of the coating.

7. Coil: recoil the galvanized steel coil and carry out quality inspection.

Fifth, the price of galvanized steel coil

The price of galvanized steel coil is affected by many factors, including raw material cost, production process, market demand, supply and so on. Therefore, different time, different brands, different specifications of galvanized steel coil prices will be different. Generally speaking, the price of galvanized steel coils produced by large steel mills is relatively stable, while the price of small steel mills or traders may be greatly affected by market fluctuations.

In order to obtain specific galvanized steel coil price information, it is recommended to contact the relevant steel mills or traders directly for consultation. wanzhi Steel is one of the top producers in China. You can learn more about galvanized steel coils from wanzhi Steel.

To sum up, galvanized steel coil with its excellent anti-corrosion performance, easy processing, environmental protection and pollution-free, high strength and economic characteristics, in construction, automobiles, home appliances and other fields have been widely used. With the development of economy and the progress of science and technology, the application prospect of galvanized steel coil will be broader.
