〣Classification of hot dip galvanizing

1, hot galvanized plate, the thin steel plate is immersed in the melted zinc groove, so that the surface adhesion of a layer of zinc thin steel plate. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously dipped in the melting zinc bath to make galvanized steel plate; Alloyed galvanized steel plate. This steel plate is also made by hot dipping, but immediately after it is out of the groove, it is heated to about 500℃ to create an alloy coating of zinc and iron. This galvanized sheet has good coating tightness and weldability.

2. Hot dip galvanizing can be divided into two types of in-line annealing and out-of-line annealing according to the different annealing methods, which are also called protective gas method and flux method.

〣specification

From 0.17~3.5 mm, 0.17~0.6 are generally color coated plate more, is with color iron plate mobile room common. Galvanized sheet is generally 0.35~3.5, its width is 1000~1800mm wide, the length is generally iron coil, so the length is not necessarily, which should be determined according to customer needs, such as 1 meter wide 2 meters long, 1250 wide 2.5 meters long.

〣material

There are many kinds of materials. Looking at the use of lz, SPCC, SGCC and DX51D+Z are common and commonly used in the general market. Other materials should be determined according to the use.
