Galvanized steel is ordinary carbon steel that’s been coated with a thin layer of zinc—most commonly by immersing the steel in a bath of molten zinc (the “hot-dip” process). The zinc coating bonds metallurgically to the steel substrate, creating a tough, corrosion-resistant barrier. Even if the coating is lightly scratched, the zinc acts sacrificially, corroding first and protecting the underlying steel from rust.

This combination of strength, durability and low maintenance makes galvanized steel a go-to choice for a wide range of applications: roofing and cladding, structural framing, fencing, automotive parts, electrical enclosures, outdoor furniture and more. Its long service life—often 50 years or more in rural environments, and 20 – 25 years in harsh coastal or industrial settings—helps drive down total life-cycle costs.
