China 200000-250000t Continuous Galvanizing Line

Hot Dipped Galvanizing
Hot galvanizing is coating one layer of zinc or sibley alloy on strip surface by hot dipping which has strong catholic protection performance and has been widely used in manufacturing, agriculture, construction and others. It has become the most useful plating product nowadays.
We have built up over hundred hot dipped galvanizing lines in domestic and overseas.
