Hot-dip galvanized strip steel is developed from strip products. Strip is a narrow and long steel product produced by various rolling mills in order to meet the needs of different industrial sectors for the production of various types of metal or mechanical products. With the continuous development of strip products and technological improvements, rolling steel companies and according to the specific needs of the industrial sector production analysis, to produce a galvanized steel, it is in the surface of the base steel through plating, hot plating, etc. evenly plated on a Layer zinc, has reached the protection of the base steel for a long time without being corroded and in some special cases can also be used in the strip. In the first place, the most pure purpose of galvanizing is to prevent corrosion of steel, and its thickness is positively correlated with protective properties. However, with the continuous improvement and development of galvanizing technology, the direction of galvanized steel is also changing, has become more and more tend to decorative.
