Galvanized Steel Plate is a material produced by continuous hot-dip galvanizing process with hot-rolled steel strip or cold-rolled steel strip as the substrate. Hot dip galvanized coil supplied in coil form after coiling. Therefore, galvanized steel sheet (coil) can be divided into hot-rolled galvanized sheet coil and cold-rolled hot-dip galvanized sheet coil. 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. Corrugated Steel Sheet,Rectangular Steel Sheet,Corrugated Galvanized Steel,Astm Rectangular Steel Sheet SHANDONG HUITONG STEEL CO.,LTD , https://www.cnhuitongsteel.com
