Galvanized Steel Sheet

Description of Galvanized Rolled Steel

Hot dipped galvanized steel sheet is a carbon steel sheet coated with zinc on both sides through a continuous hot-dip process. When the heated steel strip is in contact with the molten zinc, the coating is firmly adhered to the steel by the iron-zinc alloy adhesive layer formed by the diffusion process. One of the disadvantages of galvanizing is that if the zinc coating is scraped off the steel, the steel will lose its protection and may fail.

Recommended Products
  • Advantages of HUARO galvanized steel coils includes total protection, less maintenance, lowest long term cost, ect. Galvanized steel coil with good raw materials can meet different needs.
  • Two sides coated with commercially pure tin cold rolled low carbon sheet or steel strip. Corrosion resistance, non-toxic, tasteless, high strength and good ductility.
  • Cold rolled steel coil is made of hot rolled steel coil. The main difference of the hot and cold rolled steel coil is the thickness, surface treatment and the rolling temperature.
