Zinc Galvanized Steel Coil Hot Rolled Used For Roofing And Pipe Making
1. Description
Hot rolled galvanized steel sheets is a process of coating steel with zinc or zinc alloys in order to protect the steel base from corrosion. It has a good characteristic of resistance to corrosion, now galvanized steel is widely used in the construction industry, as raw material of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc.
