S275JR steel sheets comply with EN 10025-2 and offer an excellent combination of strength, ductility and weldability. The “JR” designation guarantees a minimum impact energy of 27 J at +20 °C, making this grade suitable for a wide variety of engineering and industrial applications. Manufacturers choose this material for metal fabrication, machinery production and steel construction because it delivers reliable performance and allows efficient processing.
Sidastico supplies cut-to-size steel sheets processed from hot-rolled coil in a wide range of thicknesses and dimensions. The company cuts every sheet according to customer specifications, reducing material waste and improving production efficiency. Sidastico also provides the EN 10204 3.1 inspection certificate with every delivery, ensuring full traceability and compliance with the declared mechanical and chemical properties.
S275JR steel sheets allow efficient laser cutting, plasma cutting, oxy-fuel cutting, bending, drilling and welding. Manufacturers use this grade for steel structures, machine frames, industrial equipment, support structures and general engineering components. Its excellent workability simplifies production while helping achieve precise and consistent results.
Compared with higher-strength steel grades, this material offers an outstanding balance between mechanical performance, ease of fabrication and cost-effectiveness. Many companies therefore select it for projects that require reliable quality without unnecessary material costs.
Sidastico combines extensive stock availability with precision cut-to-size processing, certified quality and reliable deliveries. Customers benefit from steel sheets tailored to modern industrial production and supported by fast, dependable service.
