GALVANIZED (Zinc coated sheet)

Introduction to Galvanized

NS Wheeling-Nisshin's galvanized coating is one of the most effective and economical methods of protecting bare steel from a corrosive environment. The zinc coating not only serves as a barrier between the steel and the environment, it will sacrifice itself to protect the underlying steel sheet. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.

NS Wheeling-Nisshin minimized spangle is known in the industry for its excellent paintable, flat, uniform spangle free surface. NS Wheeling-Nisshin's two state-of-the-art multi-pot coating lines provide the capability to produce a wide range of sizes, coating weights, and steel grades.

Also available is Galvanized Plus product with an acrylic coating applied to the sheet. This added coating offers additional corrosion resistance, eliminates the need for oil during rollforming, eliminates finger printing during handling, and many other advantages.

All coatings and treatments can be produced to RoHS compliance when required for your particular application.
