Galvanized steel is produced by coating the steel in zinc. The properties of galvanized steel are a unique combination that make it ideal for use in interior and exterior applications such as car bodies, appliances, nuts and bolts, roofs, and rebar.

Corrosion Resistance

According to the American Galvanizers Association, galvanized steel resists corrosion up to 100 times better than uncoated steel.

Surface Appearance

All galvanized steel has a matte-gray appearance. Zinc coating applied by using electrogalvanizing is smoother than galvanized steel made with batch or continuous galvanizing and allows for a higher quality finish when painted.


The zinc coating on galvanized steel is resistant to cracking and loss of adhesion when the steel is formed into a product.


The zinc coating does not require special handling to protect it during transport or use. It is extremely durable and resistant to scratches from abrasion.


Steel is by far the most recycled material in North America. Galvanized steel is as recyclable as other types of steel.
