What are the specifications and characteristics of galvanized sheet?

Galvanized sheet is a commonly used building material in architectural decoration. The galvanized sheet materials currently used mainly include non-alloy hot-dip galvanized steel strip and alloy hot-dip galvanized sheet, alloy galvanized sheet, hot-dip galvanized sheet, electro-galvanized steel sheet, single-sided galvanized sheet, etc., the thickness of galvanized sheet generally is 0.4 ~ 3.2mm. The galvanized sheet is coated with a layer of zinc on the surface of the steel sheet, which can play a role in anti-corrosion to a certain extent, and this production method can also reduce the consumption of zinc. In the production process of galvanized sheet, a special process is adopted. If the process and treatment methods used are different, the galvanized sheets produced are also different.

The service life of galvanized sheet has been extended for a long time mainly due to their improved corrosion resistance. Galvalume, stainless steel and aluminum panels were compared in the same humid environment. The degree of oxidation and corrosion is very slow, and the corrosion degree of stainless steel plate is relatively fast. Throughout the development of the galvanized sheet industry, some experts questioned whether the cross-section of galvanized sheet could be corroded. It turns out that the segment has been cut, but the corrosion resistance is still good. Galvanized sheet combines the antioxidant properties of zinc.

Galvanized sheet comes in a variety of types, including rulers and coils. These dimensions also have corresponding differences. The thickness of galvanized sheet is usually between 0.2mm and 3.5mm, so you can choose the appropriate thickness according to your actual needs. The width of galvanized sheet is 1000mm, 1200mm, 1250mm and 1500mm, and the length is generally 2000mm, 2500mm and so on. Galvanized sheets also have a long service life.

Since the galvanized sheet itself has good anti-corrosion performance, when it is used alone, it will naturally make it have good performance in terms of service life. On the other hand, when it is used by itself, it will also give itself a good performance in terms of aesthetics. Now more and more users use it themselves, because it has its own advantages in terms of aesthetics. This is natural as it has given it its own treatment on the surface, which naturally gives it an aesthetic edge.

At present, this material has been widely used in the construction industry, and it has gradually been used in automobiles, guardrails, and anti-corrosion steel. Traditional steel is put into the market after simple anti-rust treatment, and its service life is only a few years. The updated galvanized sheet material replaces traditional steel, and its excellent performance has been certified by multiple tests and user experience. Specific relevant information can be viewed through the data published by the manufacturer. In recent years, several related steel products have also appeared. Their corrosion resistance, rapid prototyping, surface coating and other related properties have been greatly improved. With the accumulation of technology, the manufacturing cost has been reduced, and the appearance is more beautiful.
