EN 10025-2 S275JR Steel Plate | S275JR Structural Steel
What is EN 10025-2 S275JR Steel Plate?
As a professional steel plate supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present EN 10025-2 S275JR Steel Plate (Material Number: 1.0044).
S275JR is a widely used non-alloy structural steel under the European standard EN 10025-2. It provides a minimum yield strength of 275 MPa (for thickness ≤ 16 mm) combined with good weldability, formability and toughness. The “JR” designation indicates that the material meets impact requirements of 27 J at +20°C. SHH STEEL sources this material directly from leading Chinese steel mills, ensuring competitive mill-direct pricing, stable quality and reliable delivery.
We supply S275JR steel plate in thicknesses from 6 mm to 150 mm (thicker plates available on request), widths up to 3000–4000 mm, and lengths up to 12000–18000 mm. Custom cutting, shot blasting and priming services are available. All plates are delivered with full Mill Test Certificates (EN 10204 3.1).
