The working principle of galvanized steel sheet is to coat a layer of zinc metal on the surface of the steel sheet. Its purpose is to protect the surface of the steel sheet, so that the surface can be protected from corrosion, and has reached the effect of extending the service life. Nowadays, galvanized steel sheets are used more and more widely in the market, but there are still many people who don't know the size and thickness of galvanized steel sheets.
Since today's steel sheets are basically in the shape of flat plates, their rough shapes are mostly rectangular. This shape is simple and convenient to make, and can be made directly by rolling or cutting from a wide steel strip. Galvanized steel sheets currently on the market can be divided into three types according to their thickness: if the thickness of the steel plate is less than 4 mm and can reach 0.2 mm, it is a thin steel plate; the thickness of the thick steel plate is between 4 mm and 60 mm; extra thick The thickness of the steel plate is between 60 mm and 115 mm.
With the continuous development and improvement of raw materials, mild galvanized steel sheets have more and more types of raw materials, roughly as follows: ordinary steel, high-quality steel, alloy steel, spring steel, bearing steel, silicon steel, and industrial pure iron steel. Among them, ordinary steel uses ordinary steel materials. For high-quality steel, rare metals are added on the basis of ordinary steel materials, which greatly improves the quality and performance of steel sheet. However, alloy steel is made of a variety of metal composite metals, and its function and performance are similar to products made of synthetic metal materials.
