Galvanized Steel Sheet
Hot-dip galvanized steel combines utility with beauty. It consists of tin, chrome, zinc or paint, which are the extra finish applied to the natural steel surface. The application of coating is to protect the surface of steel from oxidation and it is also used to enhance requirements for visual appearance.
Galvanized sheet coil is a kind of material produced by continuous hot-dip galvanizing process with hot-rolled steel strip or cold-rolled steel strip as substrate. Hot dip galvanized sheet is supplied with rectangular plate after cross cutting; Hot dip galvanized coil supplied in coil shape after coiling.
Therefore, galvanized sheet coil can be divided into hot-rolled galvanized sheet coil and cold-rolled hot-dip galvanized sheet coil, which are mainly used in construction, household appliances, automobile, container, transportation and home industry. Especially in steel construction, automobile manufacturing, steel warehouse manufacturing and other industries. Their main characteristics are: strong corrosion resistance, good surface quality, benefit from deep processing, economic and practical.
