Curtis Steel is a leading supplier of galvanized steel sheets & coils. Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. There are two main processes used to produce galvanized steel: continuous hot dipping and electro-galvanizing.

Hot Dipped Galvanized Steel
The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through electrolytic disposition. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer. Our hot-dipped galvanized products are manufactured to ASTM A653 specifications; our electro-galvanized products conform to ASTM A879 specifications.
A zinc coating is one of the most effective and economical methods of protecting bare steel from a corroding environment. The zinc not only serves as a barrier between the steel and the environment, but it will also sacrifice itself to protect the underlying steel sheet. Sacrificial or galvanic protection occurs when two dissimilar metals are in contact and coupled with water and oxygen. Zinc corrodes preferentially to the iron in steel. This protection prevents corrosion of the steel in areas not covered with zinc. Thus, the spread of corrosion from cut edges, drill holes, etc. is minimized.

Most gages are offered with a G90 coating, while others range from G30 to G90. Galvannealed steel is very similar to galvanized, but with differences in the coating process that result in a product much more suitable for painting. Both Galvannealed and Bonderized are commonly referred to as "Paint Grip". Hot rolled pickled and oiled is a rolled steel that has gone through a pickling process. This created an enhanced surface finish by removing any oxidized iron and applying oil to the surface to prevent rusting.
Additional large-volume steel products available to ship include cold rolled, bonderized, stainless steel, and galvalume.
Master Coils are 36", 48", and 60" wide. Custom widths and lengths for coils and sheets are available.
Custom-sized cuts require a 2,000lb minimum.
