Hot Dipped Galvanized Steel Coil For Prepainted Steel Products
0.3mm-1.0mm
1. Hot-dip zinc coated base metal
The hot dipped galvanized steel could be used for prepainted steel
producs. The prepainted steel sheet with hot-dip zinc-coated base
metal as its base metal not only has the protective function of
zinc coating but also has an isolation and protection function with
its organic layer that prevents it from rusting and prolongs its
service span longer, than that of hot-dip zinc steel sheet. The
zinc content of hot-dip zinc base metal is generally 180 per square
meters (both sides), while that of the hot-dip zinc base metal for
construction outdoors is 275 square meters per square meters. Of
course, we can also make according to customer's requirement about
zinc, the zinc range could be 40G-180G.
