SURFACE OF HOT DIP GALVANIZED STEEL COIL

Hot dip Galvanized Steel Coil is produced by continuous hot-dip galvanizing process with hot-rolled or cold-rolled steel strip as substrate. The hot-dip Galvanized Steel Sheet is supplied with rectangular flat plate after cross cutting, and the hot-dip Galvanized Coil is supplied with coil shape after coiling.The main characteristics of Zinc Coated Coil are: strong corrosion resistance, good surface quality, benefit from deep processing, economic and practical.

Therefore, hot-dip 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.

The surface structure of galvanized steel coil can be divided into Regular Spangle, small spangle and zero spangle.Regular spangle galvanized coil refers to zinc flower obtained by crystallization at normal cooling rate; small spangle refers to zinc flower whose cooling rate is specially controlled and whose size is smaller than that of normal zinc flower, and whose surface requirement is higher than that of normal zinc flower; zero spangle refers to zinc flower whose coating surface is finished for deep drawing and special surface requirement.

At present, our company can provide galvanized steel coil specifications as follows: thickness (0.15-4.0mm), width (600-1250mm), zinc layer content (20g / m2-275g / m2).So if you have any demand in galvanized steel,please feel free to contact me any time!
