Galvanized steel is a hot-dipped coated metal that provides customers with better resistance to corrosive environments.

To create galvanized steel, cold rolled steel is submerged into a molten zinc bath, known as the hot-dip process (galvanization can also be achieved through continuous galvanizing). When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs. The reaction causes the zinc coating to become part of the steel creating the well-recognized spangled finish.

Formability

Lends itself to most fabrication processes; it can be roll-formed, brake-formed, lock-seamed, deep drawn, and stretched. It can be joined by various methods including adhesive bonding, riveting, soldering and welding.

Paintable

Galvanized sheet metal can be readily painted before or after fabrication when the proper pretreatment is performed.
