EN 10025-2 S355JR H Beams and Wide Flange Beams Overview
EN 10025-2 S355JR H beams are widely used in the construction of mezzanines, industrial platforms, bridges, and general building structures. With a minimum yield strength of 355 MPa, S355JR provides reliable load-bearing capacity and excellent structural stability for medium to heavy-duty applications.
S355J2 I beams are designed for projects requiring higher toughness and strength. They are particularly suitable for creating large-span and spacious structures with minimal support columns, making them ideal for industrial halls, commercial buildings, and open-plan constructions.
EN 10025-2 S355JR W-shaped (wide flange) beams are among the most commonly used structural sections in residential and commercial construction. Their wide flanges provide improved load distribution and bending resistance, ensuring safe and efficient structural performance.

Q1: What are S355JR steel beams?
S355JR steel beams are structural steel sections manufactured in accordance with EN 10025-2. The grade S355JR indicates a minimum yield strength of 355 MPa and impact toughness tested at room temperature, making it suitable for general structural applications.
Q2: Which standard applies to S355JR steel beams?
S355JR steel beams are produced under EN 10025-2, the European standard for hot-rolled structural steels. This standard defines chemical composition, mechanical properties, impact test requirements, and delivery conditions.
Q3: What mechanical properties does S355JR steel offer?
S355JR steel typically provides a minimum yield strength of 355 MPa, tensile strength ranging from approximately 470 to 630 MPa, and good elongation. These properties ensure reliable load-bearing capacity and structural safety.
Q4: What does the "JR" designation mean in S355JR?
The "JR" designation indicates that the steel has a minimum impact energy of 27 J tested at +20°C. This confirms adequate toughness for structures operating under normal ambient temperature conditions.
Q5: How does S355JR compare with S275JR steel beams?
Compared with S275JR, S355JR offers higher yield and tensile strength, allowing for reduced section sizes or higher load capacity. This often results in weight savings and improved structural efficiency.
Q6: Is S355JR steel beam suitable for welding?
Yes, S355JR steel beams exhibit good weldability due to controlled carbon content and low carbon equivalent (CE). Standard welding methods can be applied with proper welding procedures and preheating when required by thickness.
Q7: Can S355JR steel beams be used in bolted and riveted connections?
S355JR steel beams are well suited for bolted and riveted connections. Their mechanical properties ensure reliable performance under static and dynamic loads when proper design standards are followed.
Q8: What types of steel beams are commonly supplied in S355JR?
S355JR is widely available in I-beams, H-beams, HEA, HEB, HEM sections, and universal beams. Availability depends on rolling mill capabilities and regional standards.
Q9: What are typical applications of S355JR steel beams?
S355JR steel beams are commonly used in industrial buildings, commercial structures, bridges, platforms, power plants, warehouses, and heavy machinery frames where strength and reliability are required.
Q10: How does S355JR perform in low-temperature environments?
S355JR is suitable for standard temperature environments. For low-temperature service, grades such as S355J0 or S355J2 are recommended due to their improved impact toughness at lower test temperatures.
Q11: What surface condition is supplied for S355JR steel beams?
S355JR steel beams are typically supplied in the hot-rolled, as-rolled condition with mill scale on the surface. Additional surface treatments such as shot blasting, priming, galvanizing, or painting can be applied upon request.
Q12: What length and size ranges are available for S355JR steel beams?
S355JR steel beams are commonly supplied in standard lengths such as 6 m, 12 m, or customized cut-to-length options. Section sizes depend on beam type and mill production range.
