BRIEF
Hot-dip galvanized steels are produced by using cold-rolled or hot-rolled steel sheets as substrates, hop-dip galvanizing steel sheets by series of processing procedures, in a continuous hot-dip galvanizing production line, and output a kind of galvanized steel sheets.
HD Galvanized Steels forms a coating composite consisting of alloy layer and coated metal in the outside metal substrate, which has a sacrificial protective effect on the corrosion of the metal substrate. The galvanized steel sheets have ideal comprehensive properties such as corrosion resistance, forming and painting, and have the advantages of low cost and good appearance. They have large output in the market, many varieties and wide range of uses. Hot-dip galvanized steels are excellent materials for buildings and applications.
With different coating compositions, HD Galvanized Steels have:
Galvanized (GI) Al<=0.15%
Galvalume (GL) 55%Al-43.3%Zn-1.6%Si
Galfan (GF) Zn-5%Al-RE
Galvanneal (GA) Zn-Fe
Zn-6%Al-3%Mg
Etc…
Hod Dip Galvanized Steels, GI, GA, GF, GL, etc.
