Hot-Dip Galvanized Steel

We supply premium Hot-Dip Galvanized Steel (HDG / GI) produced through a continuous hot-dip galvanizing process, where cold-rolled or hot-rolled steel is uniformly coated with a protective layer of zinc. This coating delivers exceptional corrosion resistance, excellent formability, and long-term durability, making HDG steel ideal for construction, automotive, electrical, and industrial applications.
