Frequently Asked Questions About S355JR Steel Plates
S355JR is a low carbon, high strength structural steel plate grade under EN 10025-2 standard. It offers excellent weldability, impact resistance at sub-zero temperatures, and is ideal for structural fabrication, bridges, offshore structures, and heavy machinery.
S355JR plates are available in thicknesses ranging from 6 mm to 300 mm and widths up to 3500 mm. Lengths can be customized between 3000 mm to 12000 mm as per client requirements.
S355JR plates are produced according to the EN 10025-2 standard for hot-rolled structural steel products. It meets European and international quality benchmarks for mechanical and chemical properties.
The weight of an S355JR steel plate is calculated using the formula: Weight (kg) = Thickness (mm) × Width (mm) × Length (mm) × 7.85 ÷ 1,000,000. This factor (7.85) is the standard density of carbon steel in kg/m³.
Prices depend on thickness & quantity, contact for best rate.
