Electrogalvanized (EG), hot-dipped galvanized (HDG or GI), galvannealed (GA) and galvalume (GM) are cold rolled carbon steel coated with a zinc- or aluminum-based substance for corrosion resistance. The coating serves as a sacrificial anode, so that it cathodically protects exposed steel. This means that even if the coating is scratched or abraded, the exposed steel will still be protected from corrosion by the remaining zinc – an advantage absent from paint, enamel, powder coating and other methods.
Galvanized is used widely in the automotive, construction and appliance sectors for products that are exposed such as roofing, siding, ceiling systems, HVAC ducting, electrical boxes, building components, grain bins, garage doors and industrial packaging. To enhance performance in specific end uses, galvanized steel is often painted, coated, and/or laminated as well.
