Perforated steel sheet is often galvanized for increased corrosion resistance. Galvanizing is a process that involves coating the steel sheet with a thin layer of zinc. The zinc acts as a barrier, protecting the steel from corrosion and oxidation. The added corrosion resistance makes galvanized perforated steel sheets an ideal choice for outdoor applications, such as stair treads, fence panels, and protective grates.

Generally speaking, the cold rolled steel is based on the hot rolled steel. With the further processing, it can form the cold rolled steel. The cold rolled steel is processed in cold reduction mills, and then the temperature can be cooled down through the annealing process and tempers rolling. The

According to the manufacturering process, there are two types of metal, the hot roll metal and cold roll metal. What are the difference between the two types of metal sheet? The mainly difference is temperature. The hot roll steel is made under the high temperatures. The cold roll steel bascially is
