Several points should be paid attention to when choosing galvanized mild steel sheets. Customers of industrial enterprises should pay attention to four standards when choosing special industrial raw materials. The first is to pay attention to the brand to choose. Because the galvanizing technology is strict, there is a foundation for a big brand. Of course, the product quality and technical standards will be more reliable, and there will be better professional standards. The second is to pay attention to the quality of the coating of the product itself. The coating depends on technology and purity. Therefore, from the surface of the product, this is the most basic and most important standard. The third is to look at the basic material, because the quality of the basic metal material of the galvanized steel sheet is closely related to the quality and durability of the final finished galvanized steel sheet, so when choosing products, we must pay attention to this detail, and the provision of high-quality materials , That is, for industrial production, there are basic conditions for quality assurance. Fourth, we must pay attention to price comparison, which is either the best or the most expensive, but if it is a cheap product, it must be unreliable.
①Hot-dip galvanized steel sheet. The thin steel plate is immersed in the molten zinc tank, so that a thin steel plate with a layer of zinc is adhered to the surface. At present, the continuous galvanizing process is mainly used for production, that is, the rolled steel sheet is continuously immersed in the molten zinc plating tank to make the galvanized steel sheet;
②Alloyed galvanized steel sheet. This kind of steel plate is also manufactured by hot dipping method, but immediately after leaving the tank, it is heated to about 500°C to form an alloy film of zinc and iron. This kind of galvanized steel sheet has good paint adhesion and weldability.
③Electro-galvanized steel sheet. The galvanized steel sheet produced by the electroplating method has good workability. However, the coating is thinner and the corrosion resistance is not as good as the hot-dip galvanized steel sheet;
④Single-sided and double-sided differential galvanized steel sheet. Single-sided galvanized steel sheet is a product that is galvanized on one side only. In welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized steel. In order to overcome the shortcomings of uncoated zinc on one side, there is another galvanized steel sheet coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized steel sheet;
⑤Alloy and composite galvanized mild steel sheet. It is a steel plate made of zinc and other metals such as lead and zinc alloys and even composite plating. This kind of steel plate not only has excellent anti-rust performance, but also has good coating performance.
