GI Steel Applications
Our galvanized steel products are widely used in various industrial sectors due to their excellent corrosion resistance, mechanical properties, and processability.
Direct Applications
This type of application typically uses galvanized steel coils/sheets as a direct component of the final product, with minimal changes in shape or surface treatment.

Building Roofs and Exterior Walls
Galvanized sheet or profiled sheet is directly used for roofs and walls of industrial plants, warehouses, stations, and more.

Ventilation Ducts
Galvanized sheet is the primary material for supply and exhaust ducts due to its corrosion resistance, ease of processing, and reasonable cost.

Grain Silos and Storage Equipment
Used in grain storage silos, feed towers, and containers.

Simple structural parts
Such as cable trays, cable troughs, lighting poles, highway guardrails, etc.
Post-Processing Applications
This type of application uses galvanized steel coils/sheets as raw materials, and then processes them through stamping, shearing, spraying, welding, and other processes to create more complex components or products.

Home Appliance
- Processing: Stamping, Bending, Pre-Painting.
- Applications: Housings and internal components for refrigerators, washing machines, air conditioners, microwave ovens, computer cases, etc.

Automotive Parts
- Processing: High-precision stamping and welding.
- Applications: Automotive body panels (doors, hoods, trunk lids), chassis parts, etc.

Civil Construction/Home Furnishings
- Processing: Forming, Shearing, Pre-Painting.
- Applications: Color-coated steel sandwich panels, roof panels, ceiling panels, steel furniture, filing cabinets, fire-rated doors, etc.

Containers and Packaging
- Processing: Stamping and welding.
- Applications: Washing machine drums, water tanks, barrels, metal packaging cans (such as paint cans), etc.
