Application of galvanized coil sheet

galvanized sheet is light in weight, beautiful in appearance, good in corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, automobile manufacturing industry, furniture industry, electrical industry, etc. It has good effects such as replacing wood with steel, efficient construction, energy saving, and pollution prevention. The color-coated steel plate uses galvanized steel plate as the base material. In addition to zinc protection, the organic coating on the zinc layer also plays the role of covering and isolation, which can prevent the steel plate from rusting and has a longer service life than galvanized steel plate. Coated steel is said to last 50% longer than galvanized steel. However, the service life of color-coated sheets with the same amount of galvanization, the same coating material and the same coating thickness will vary greatly in different regions and different places of use. For example, in industrial areas or coastal areas, due to the influence of sulfur dioxide gas or salt in the air, the corrosion rate is accelerated and the service life is affected. In the rainy season, if the coating is soaked in rainwater for a long time or the temperature difference between day and night is too large, condensation is likely to occur, the coating will corrode rapidly, and the service life will be shortened. Buildings or workshops made of color-coated steel plates usually have a long service life when they are washed by rainwater, otherwise, their use will be affected by sulfur dioxide gas, salt and dust. Therefore, in the design, if the roof has a large slope, it is less likely to accumulate dirt such as dust and has a longer lifespan. Areas or parts that are not frequently washed by rain should be flushed with water on a regular basis.

• The thin steel plate is immersed in the dissolved zinc bath so that its surface adheres to a thin steel plate. It is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the plating groove dissolved with zinc to make galvanized steel plate. This steel plate is also made by hot immersion, but after the groove, it is immediately heated to about 500 ℃, so that it generates an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weld ability.
• Galvanized coil can be divided into hot rolled galvanized coil and cold rolled galvanized coil, they are mainly used in the construction of household appliances, car containers, transportation and other fields, especially steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries their characteristics are mainly: strong corrosion resistance, good surface quality, economic and practical.
