What Is HEA 360 35030010*17.5 S355J0 Steel Profile?
HEA 360 35030010*17.5 S355J0 Steel Profile is a European lightweight wide-flange structural beam manufactured from S355J0 steel. Its actual section height is 350 mm, flange width is 300 mm, web thickness is 10 mm, and flange thickness is 17.5 mm.
The HEA series uses a relatively thin web and flanges to reduce structural dead weight while maintaining useful bending strength and stiffness. With a theoretical weight of approximately 112 kg/m, the S355J0 HEA 360 wide flange H beam is suitable for industrial buildings, roof structures, floor systems, equipment platforms, and other projects where structural efficiency and lower self-weight are important.
Dimensions of S355J0 HEA 360 35030010*17.5 H Beam
The designation HEA 360 refers to the standard profile series rather than its exact height. According to standard European section tables, the actual overall height of this profile is 350 mm.

S355J0 HEA 360 Steel Chemical Composition
S355J0 is an EN 10025-2 structural steel with controlled carbon and manganese contents. Its composition provides a practical combination of structural strength, impact 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 |
These figures are general standard limits. The actual heat analysis of each S355J0 HEA 360 Steel Profile should be verified using the corresponding EN 10204 3.1 mill test certificate.
Mechanical Properties of HEA 360 S355J0 H Profile Steel
The flange thickness of this HEA 360 section is 17.5 mm. Therefore, it falls within the thickness range over 16 mm to 40 mm under EN 10025-2.
| Mechanical Property | Requirement |
|---|---|
| Minimum yield strength, ReH | 345 MPa |
| Tensile strength, Rm | 470–630 MPa |
| Minimum elongation | 22% |
| Charpy V-notch impact energy | Minimum 27 J at 0°C |
Although the grade is designated S355J0, the guaranteed minimum yield strength decreases to 345 MPa when the nominal product thickness exceeds 16 mm. This thickness-dependent value should be used for engineering calculations involving the 17.5 mm flange.
Why Choose HEA 360 Instead of HEB 360?
HEA 360 has a lighter section than HEB 360. Its thinner web and flanges reduce steel consumption and foundation loads, making it a cost-effective option when the design does not require the heavier cross-section of an HEB beam.
| Comparison | HEA 360 | HEB 360 |
|---|---|---|
| Section height | 350 mm | 360 mm |
| Flange width | 300 mm | 300 mm |
| Web thickness | 10 mm | 12.5 mm |
| Flange thickness | 17.5 mm | 22.5 mm |
| Theoretical weight | Approx. 112 kg/m | Approx. 142 kg/m |
| Main advantage | Lower structural weight | Higher section capacity |
HEA 360 is often considered for beams and framed structures where weight efficiency matters. HEB 360 may be more suitable for heavily loaded columns or members requiring greater local and overall stiffness. Final selection must be confirmed through structural calculations.
Processing of HEA 360 35030010*17.5 S355J0 Steel Profile
The HEA 360 35030010*17.5 S355J0 Steel Profile can be supplied in mill lengths or processed according to structural drawings. Available services include:
- Fixed-length CNC sawing
- Flange and web drilling
- End-plate and base-plate welding
- Coping and notching
- Bevel preparation
- Shot blasting
- Primer or finish painting
- Hot-dip galvanizing
- Component marking and bundled packing
For welded fabrication, the welding procedure should be selected according to the material carbon equivalent, section thickness, joint restraint, welding consumables, and ambient temperature.
Because S355J0 is a conventional structural steel rather than a weather-resistant grade, suitable coating or galvanizing should be specified when the profile will be installed outdoors or in a corrosive environment.
Inspection of S355J0 HEA 360 Wide Flange Beam
Before shipment, the material can be inspected for overall height, flange width, web thickness, flange thickness, length, straightness, surface condition, and identification markings.

- Tensile and yield test results
- 0°C impact test results
- Dimensional inspection report
- Surface and visual inspection records
