Galvanized steel coil is a specially treated steel product whose production process includes a number of fine steps. First, the raw material is all-hard board, which requires a pickling process to remove surface impurities and oxide layers, and then a rolling process to achieve the desired thickness and smoothness. The sheets are then fed into a zinc pan, where they are coated with a uniform and continuous zinc film. This layer of zinc film can not only effectively isolate the direct contact between the air and the substrate, thus greatly enhancing the corrosion resistance of the material; At the same time, because the zinc itself has good plasticity and ductility, the galvanized steel plate also has better processing and forming ability and good coating adhesion.
Hot-dip galvanizing technology is one of the most widely used methods for surface protection of steel products, which takes advantage of the unique electrochemical properties of zinc - when zinc is used as a sacrificial anode, it can be preferentially corroded by oxidation over iron, thereby protecting the internal base metal from damage. This method is especially suitable for those components or equipment that need to be exposed to the outside environment for a long time, such as building structures, Bridges, highway guardrails, etc.
According to the requirements of different application scenarios, the manufacturer can also adjust the specific thickness range of the galvanized layer, which can usually reach a maximum of about 120 grams per square meter. In addition, in cases where the appearance quality of the final product is required to be high, additional polishing treatment can also be selected to obtain a smoother and more delicate surface effect. According to whether such a follow-up processing process is carried out, the common galvanized steel coil on the market can be divided into two categories: zero spot type (that is, no additional treatment is done) and ultra-smooth type.
