They are mainly used in the fields of construction, household appliances, automobiles, containers, transportation and household industry. Especially in steel structure construction, automobile manufacturing, steel warehouse manufacturing and other industries. Their main characteristics are: strong corrosion resistance, good surface quality, benefit from deep processing, economy and practicality, etc.
