Why Choose Our S275 Medium Plate?

Consistent Quality: Strict control over rolling temperature (controlled rolling/cooling) ensures uniform mechanical properties across the plate.

Cost-Effective: Lower alloy content than high-strength grades (e.g., S355) while meeting most structural needs, reducing project costs.

Customization: Flexible thickness/width/length options, plus tailored surface treatment to match on-site installation schedules.

Reliable Supply: Annual production capacity of 50,000+ tons, with lead times of 7-15 days for standard specs.

FAQ

Q: What standard does S275 medium plate comply with?

A: It follows the European standard EN 10025-2, a key specification for hot-rolled structural steels.

Q: What's the minimum yield strength of S275 medium plate?

A: For plates ≤16mm thick, the minimum yield strength is 275 MPa; for 16-40mm thick plates, it's 265 MPa.

Q: Is S275 medium plate easy to weld?

A: Yes, it has excellent weldability, which ensures strong, leak-proof joints-ideal for structural and tank fabrication.

Q: What thickness range is available for S275 medium plate?

A: Typical thickness is 6mm-200mm; 10mm-50mm for general structures, and 50mm-200mm for heavy machinery.

Q: What are the common quality grades of S275 medium plate?

A: Main grades are S275JR (general use), S275JO (impact test at 0°C), and S275J2 (impact test at -20°C). S275J2 is widely used for harsh environments.
