JIS Standard Compliance Ensures Quality Consistency
All three grades strictly adhere to JIS G 3302, a globally recognized standard governing hot-dip galvanized steel sheets and coils. This ensures uniform specifications for:
Zinc coating thickness (typically 60–275 g/m², customizable by application).
Chemical composition (controlled levels of carbon, manganese, and impurities).
Mechanical performance metrics (yield strength, tensile strength, elongation).
Standardization guarantees reliability across production batches and suppliers.
Differentiated Mechanical Properties for Targeted Uses
Each grade is engineered with distinct strength and ductility to suit specific forming needs:
SGCC (General-Purpose Grade)
Strength: Low to moderate (yield strength: 200–340 MPa; tensile strength: 270–410 MPa).
Formability: Excellent ductility and bendability, ideal for complex shaping (e.g., bending, shallow drawing, and stamping).
Applications: Household appliances (refrigerator panels, washing machine parts), automotive trim, and light structural components.
SGHC (High-Formability Grade)
Strength: Moderate (yield strength: 180–300 MPa; tensile strength: 270–380 MPa).
Formability: Superior elongation (up to 35%), enabling severe forming processes like deep drawing, stretching, and contouring without cracking.
Applications: Deep-drawn products (metal cans, barrels), curved automotive parts, and precision metalwork requiring tight dimensional control.
SGC400 (High-Strength Grade)
Strength: High (yield strength: ≥400 MPa; tensile strength: ≥510 MPa).
Formability: Balances strength with adequate ductility, supporting basic to moderate forming (e.g., folding, simple stamping).
Applications: Structural components (construction frames, machinery supports), load-bearing panels, and parts needing both strength and shape versatility
SGHC (High-Formability Grade)
Strength: Moderate (yield strength: 180–300 MPa; tensile strength: 270–380 MPa).
Formability: Superior elongation (up to 35%), enabling severe forming processes like deep drawing, stretching, and contouring without cracking.
Applications: Deep-drawn products (metal cans, barrels), curved automotive parts, and precision metalwork requiring tight dimensional control.
