Claims4
A multilayer coated corrosion resistant steel material which has on its surface a multilayer protective coating said multilayer coated corrosion resistant steel material consisting essentially of a steel base having at least one surface;
- a galvanized zinc layer having a thickness between approximately 8-20 microns thick on said steel surface;
- an electroplated deposited layer of zinc based alloy containing 5-15% by weight nickel deposited on said galvanized zinc layer and having a thickness of one to six microns;
- and a vinyl fluoride resin layer on said electroplated layer.
