Sri Sakthi Steels

Galvanized Iron (GI) sheets, defined by ASTM A653 and IS 277 standards, typically feature a mild steel base coated with zinc, offering high strength, durability, and corrosion resistance. Key properties include a tensile strength of 300-600 MPa, 25-55 ksi minimum yield strength, and 20-40% elongation, providing excellent formability for bending and roll-forming.
Mechanical Property Breakdown Yield Strength: Generally ranges from 

• 140 MPa140 MPa140 MPa to over 550 MPa550 MPa550 MPa (approx. 25-55 ksi) depending on the grade, such as commercial or structural quality.
• Tensile Strength: Ranges from 270 MPa270 MPa270 MPa to 600 MPa600 MPa600 MPa (approx. 50-65 ksi), ensuring strong, load-bearing capability.
• Elongation: Typically 20-40%, indicating good ductility for drawing and shaping operations.
• Hardness: Generally falls within 50-70 HRB, though some grades may range higher (up to HRB 95).
• Formability: High, with excellent performance in lock-seaming, bending, and roll-forming, making it suitable for roofing and structural components. 
• Key Characteristics 

Coating Impact: The zinc coating (typically 60-750 g/m²) does not significantly alter the base steel's mechanical properties, but thicker coatings can slightly reduce formability.

• Durability: Excellent corrosion resistance ensures long-term structural integrity.
• Standard Grades: Common specifications include JIS G3302 (SGCC), ASTM A653, and IS 277.
