1.Hot dipped galvanized steel coil description
Hot dipped galvanized steel coil is hot-dip galvanizing is a process that involves coating metals such
as steel and iron with a thin layer of zinc.Pure zinc layer then turns into zinc oxide when it is exposed
to oxygen, and finally zinc carbonate after exposure to carbon dioxide.

2.Hot dipped galvanized steel coil technical process
After cleaning and acid pickling, the steel coil is submerged in melted zinc, a chemical reaction
permanently bonds the zinc. The zinc actually permanently becomes a part of it and the
successive layers are a mixture of zinc and iron.Hot dipped galvanized steel coil is a special type
of steel coil used in a number of different applications within fabrication and manufacturing environments
