• Strong corrosion resistance : GI steel is coated with a layer of zinc through a hot-dip galvanizing process, which provides excellent protection against rust and corrosion. The zinc acts as a sacrificial layer, meaning it corrodes first, thereby protecting the underlying steel. This makes GI ideal for harsh environments, including outdoor construction, industrial applications, and marine climates.

• High surface quality : The galvanizing process ensures a smooth, uniform zinc coating with minimal defects. GI steel has a bright, clean appearance and can be further treated (e.g., painted or laminated) for enhanced aesthetics and performance. Its consistent surface quality makes it suitable for visible applications like roofing, panels, and appliances.

• Conducive to deep processing, such as corrugated steel sheet : GI steel is highly formable and ductile, allowing for deep processing such as bending, stamping, and roll-forming. This makes it a preferred material for manufacturing **corrugated steel sheets**, automotive parts, and structural components. The zinc coating remains intact even after shaping, ensuring long-term durability.

• Economy and practicality : Compared to other corrosion-resistant materials (e.g., stainless steel), GI steel offers a cost-effective solution without compromising performance. Its long service life reduces maintenance costs, and its versatility makes it widely used in construction, agriculture, HVAC, and household appliances.
