What Is S355J0 HEB 700*300*17*32 H Beam?
S355J0 HEB 700*300*17*32 H-beam is a heavy European wide-flange structural section manufactured from S355J0 steel according to EN 10025-2. Its nominal section height is 700 mm, flange width is 300 mm, web thickness is 17 mm, and flange thickness is 32 mm. The theoretical weight is approximately 241 kg/m.
Compared with lighter HEA sections, the thicker web and flanges of the S355J0 HEB 700*300*17*32 wide flange H beams provide greater bending resistance, stiffness, and load-bearing capacity.
This profile is commonly selected for industrial buildings, large-span structures, bridge components, heavy columns, equipment-support frames, and infrastructure projects.
S355J0 HEB 700*300*17*32 Steel Profile Dimensions
The S355J0 HEB 700*300*17*32 Steel Profile combines a deep 700 mm section with 300 mm-wide flanges. Its large cross-sectional area and strong-axis section modulus make it suitable for structural members subjected to high bending moments or axial loads.

Chemical Composition of S355J0 HEB 700*300*17*32 H Profile Steel
The controlled carbon, manganese, phosphorus, and sulfur contents help the S355J0 HEB 700*300*17*32 H Profile Steel maintain a practical balance between strength, toughness, weldability, and fabrication performance.
| Element | Maximum Content (%) |
|---|---|
| Carbon, C | 0.22 |
| Silicon, Si | 0.55 |
| Manganese, Mn | 1.60 |
| Phosphorus, P | 0.035 |
| Sulfur, S | 0.035 |
| Nitrogen, N | 0.012 |
| Copper, Cu | 0.55 |
The values above are general EN 10025-2 limits for reference. The actual chemical composition should be confirmed through the EN 10204 3.1 mill test certificate supplied with the batch.
Mechanical Properties of S355J0 HEB 700 Wide Flange H Beams
Because the flange thickness is 32 mm, the thickness-dependent minimum yield strength is normally 345 MPa rather than 355 MPa. This does not change the material designation: S355J0 remains the grade name, while EN 10025-2 specifies different guaranteed yield strengths for different thickness ranges.
| Mechanical Property | Typical Requirement |
|---|---|
| Minimum yield strength, ReH | 345 MPa for thickness over 16–40 mm |
| Tensile strength, Rm | 470–630 MPa |
| Minimum elongation | 22% |
| Charpy V-notch impact energy | Minimum 27 J at 0°C |
The 0°C impact requirement makes S355J0 HEB 700*300*17*32 wide flange H beams suitable for structural projects requiring verified toughness under moderate-temperature service conditions.
However, the final material grade should always be selected by the project engineer based on design temperature, load, fatigue, welding, and local building-code requirements.
Processing of S355J0 700*300*17*32 HEB Beam
The S355J0 700*300*17*32 HEB beam can be supplied as full-length material or processed according to fabrication drawings. Available processing can include CNC sawing, flame cutting, drilling, coping, beveling, welding, base-plate assembly, shot blasting, priming, painting, and hot-dip galvanizing.
For welded structures, the welding procedure and preheating requirement should be determined according to the actual carbon equivalent, restraint level, section thickness, ambient temperature, and welding consumables. Because S355J0 is not a weathering steel grade, beams used outdoors should normally receive a suitable painting, galvanizing, or other corrosion-protection system.
Inspection of S355J0 HEB 700*300*17*32 Steel Profile
Before shipment, the S355J0 HEB 700*300*17*32 Steel Profile can be inspected for section dimensions, length, straightness, flange and web thickness, surface condition, and identification marking. Chemical composition, tensile properties, yield strength, elongation, and impact performance can be verified through the mill test certificate.
Optional third-party inspection by SGS, BV, TÜV, or another nominated agency can also be arranged when required. Ultrasonic testing, magnetic particle testing, weld inspection, coating-thickness testing, and dimensional reports are available subject to the project specification.
Applications of S355J0 HEB 700 H Beam
Due to its large section depth and high stiffness, the S355J0 HEB 700*300*17*32 H Beam is commonly used in:
- Heavy industrial building columns and main beams
- Large-span factories and warehouse structures
- Bridge supporting members and infrastructure
- Power plant and petrochemical steel structures
- Crane-support frames and equipment platforms
- Offshore and port-related structural frames
- Transfer beams and high-load structural columns
The section size alone does not determine safe load capacity. Structural calculations must consider span, restraint, buckling length, connection design, load combination, and applicable engineering codes.
We can supply S355J0 HEB 700*300*17*32 H Beam in standard or customized lengths, with cutting, drilling, welding, blasting, painting, galvanizing, and third-party inspection services. Material certificates and dimensional inspection documents can be supplied for order verification.
