What Is HEB260x260x10x17.5 S355J0 H Beam?
HEB260x260x10x17.5 S355J0 H Beam for construction is a European standard wide-flange structural section manufactured from S355J0 steel. Its cross-section measures 260 mm in height, 260 mm in flange width, 10 mm in web thickness, and 17.5 mm in flange thickness.
With a theoretical weight of approximately 93 kg/m, the S355J0 HEB 260 H Beam provides a practical combination of strength, stiffness, structural stability, and fabrication performance.
It is commonly used for building columns, main beams, equipment supports, industrial frames, platforms, and other load-bearing construction components.
Dimensions of S355J0 HEB260x260x10x17.5 Steel Profile
The dimensions of the HEB260x260x10x17.5 S355J0 Steel Profile generally comply with EN 10365. Section tolerances, including height, width, thickness, straightness, and flange squareness, can be controlled according to EN 10034.

| Dimensional tolerance | EN 10034 |
| Overall height, h | 260 mm |
| Flange width, b | 260 mm |
| Web thickness, tw | 10 mm |
| Flange thickness, tf | 17.5 mm |
| Root radius, r | Approx. 24 mm |
| Clear web depth, d | Approx. 177 mm |
| Cross-sectional area | Approx. 118 cm² |

The wide parallel flanges provide sufficient space for bolted connections, end plates, base plates, and stiffeners. This makes the HEB260 S355J0 H Profile Steel convenient for both workshop fabrication and construction-site installation.
Section Properties of HEB 260 Wide Flange H Beam
The following section data can be used for preliminary comparison and material selection:
| Section Property | Approximate Value |
|---|---|
| Cross-sectional area | 118 cm² |
| Strong-axis moment of inertia, Ix | 14,920 cm⁴ |
| Strong-axis elastic section modulus, Wx | 1,148 cm³ |
| Strong-axis plastic section modulus, Wpl,x | 1,283 cm³ |
| Weak-axis moment of inertia, Iy | 5,135 cm⁴ |
| Weak-axis elastic section modulus, Wy | 395 cm³ |
| Weak-axis plastic section modulus, Wpl,y | 602 cm³ |
The large strong-axis moment of inertia helps the HEB260x260x10x17.5 wide flange H beam resist bending and deflection. Its wide flange also improves weak-axis stability compared with narrower beam sections.
These values describe the geometry of the profile. Final design resistance must be calculated based on Eurocode 3 or the applicable local structural standard.
Weight of HEB260x260x10x17.5 S355J0 H Beam
The theoretical unit weight of the HEB260x260x10x17.5 S355J0 H Beam is approximately 93 kg/m.
Weight per piece = 93 kg/m × beam length
| Beam Length | Theoretical Weight |
|---|---|
| 6 m | Approx. 558 kg |
| 9 m | Approx. 837 kg |
| 12 m | Approx. 1,116 kg |
| 15 m | Approx. 1,395 kg |
| 18 m | Approx. 1,674 kg |
For example, 25 pieces of 12 m HEB 260 beams have a theoretical total weight of approximately 27.9 tonnes. Actual shipping weight may vary slightly within permitted rolling tolerances.
S355J0 HEB 260 Chemical Composition
S355J0 is a weldable non-alloy structural steel specified under EN 10025-2. The following values are general maximum limits for long products.
| 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 actual chemical composition of each batch should be verified using the corresponding heat number and EN 10204 3.1 mill test certificate.
Mechanical Properties of HEB260 S355J0 H Profile Steel
The flange thickness of HEB 260 is 17.5 mm, placing it in the thickness range over 16 mm and up 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 steel is designated S355J0, its minimum guaranteed yield strength is thickness-dependent. For the 17.5 mm flange, 345 MPa should normally be used during design verification.
Why Is HEB260 S355J0 Suitable for Construction?
The HEB260x260x10x17.5 S355J0 H Beam for construction offers several advantages for load-bearing steel structures.
Its 260 mm-wide flanges improve lateral stability and provide practical surfaces for welded or bolted connections. The S355J0 material offers higher strength than common S235 structural steel, allowing designers to achieve the required capacity without unnecessarily increasing the section size.
The grade also provides guaranteed impact performance at 0°C, making it suitable for construction projects requiring verified toughness at moderate service temperatures. Its controlled chemical composition supports cutting, drilling, welding, and other fabrication operations.
Processing of HEB260x260x10x17.5 S355J0 Steel Profile
The HEB260x260x10x17.5 S355J0 Steel Profile can be supplied in standard mill lengths or fabricated according to construction drawings.
