Introduction to Galvalume®

corrosion resistant coated sheet metal in product warehouse

WHEELING-NIPPON STEEL's GALVALUME® steel sheet combines the excellent barrier corrosion protection of aluminum with the galvanic protection of zinc. Its corrosion resistance far exceeds that of galvanized, is suitable for applications where rust prevention is imperative, has superior flatness, uniform spangle and is an excellent surface suitable for painting. It provides versatility, ease of use, aesthetics and continues to gain approval worldwide by specifiers, architects, building owners and many others due to its exceptional performance as a material for building and architectural applications. Our Galvalume® is produced to ASTM A792 specifications.

Also available is Galvalume® 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.
