The S355JR structural hot rolled carbon steel coil conforms to EN 10025-2 and delivers a guaranteed yield strength of 355 MPa, making it one of the most widely specified structural grades in European and Middle Eastern construction markets. Zhengde produces S355JR coils with tightly controlled chemistry and rolling parameters to ensure the mechanical property envelope remains stable from the first meter to the last meter of every coil. The grade offers an excellent combination of strength, weldability and toughness, with Charpy impact energy of at least 27 Joules at room temperature, which is essential for dynamically loaded structures and prefabricated building components. Available in thicknesses from 1.5mm to 20mm and widths from 600mm to 2000mm, the coil can be supplied in mill finish or pickled and oiled surface condition to suit different fabrication routes. Each coil is verified through tensile, bending and impact testing in accredited laboratories, and the accompanying EN 10204 3.1 certificate confirms full compliance for projects requiring documented material quality. Fabricators benefit from consistent flatness and thickness that reduce reject rates in laser cutting, plasma cutting and CNC punching operations.

• EN 10025-2 Compliant: Full European standard compliance with EN 10204 3.1 mill certificates accepted by global engineering consultants
• Reliable 355MPa Yield: Guaranteed minimum yield strength supports lighter sections and cost-effective structural design
• Consistent Through-Coil Quality: Stable chemistry and rolling practice deliver uniform strength and hardness across the entire coil
• High Productivity Fabrication: Excellent flatness and thickness consistency minimize rejects in laser and plasma cutting lines
• Good Impact Toughness: Minimum 27J Charpy energy at room temperature suits dynamic and seismic-resistant structures
• Flexible Supply Forms: Available in mill finish, pickled and oiled, slit edge or trimmed edge to match downstream processes

S355JR coils are used in prefabricated steel buildings, portal frames, mezzanine floors, roof trusses, agricultural machinery, earthmoving equipment, conveyor structures, storage racks, transmission towers and general engineering fabrication where EN 10025 structural steel is specified by consultants and contractors.
