HEA HEB Steel Profile H beam S355J2 Structure Steel
S355J2 H profile steel is a high-strength low-alloy structural steel produced according to EN 10025-2 (Material No. 1.0577). It is widely used in heavy construction projects where both high strength and low-temperature toughness are required.
S355J2 H profile steel
Compared with standard structural grades such as S355JR, S355J2 steel is impact-tested at -20°C, ensuring reliable performance in cold climates and demanding environments.
European standard HEA and HEB H-beams are commonly manufactured using this material and are widely used in:
- Steel structure buildings
- Bridges and infrastructure projects
- Offshore platforms
- Wind power towers
- Industrial equipment frames
As a professional structural steel supplier, we provide S355J2 HEA and HEB H beams with certified quality, large stock availability, and global shipping services.
HEA vs HEB H Beam – What's the Difference?
The two most common European H beam profiles are HEA and HEB. While they share the same profile shape, their weight, flange thickness, and load capacity are different.
| Profile Type | Description | Typical Application |
|---|---|---|
| HEA Beam | Lightweight H beam with thinner flange | Medium-load structures, building frames |
| HEB Beam | Heavier beam with thicker flange and web | Heavily loaded structures and industrial buildings |
Example Dimensions
| Profile | Height (mm) | Flange Width (mm) | Web Thickness (mm) | Flange Thickness (mm) |
|---|---|---|---|---|
| HEA 100 | 96 | 100 | 5 | 8 |
| HEA 200 | 190 | 200 | 6.5 | 10 |
| HEB 200 | 200 | 200 | 9 | 15 |
| HEB 300 | 300 | 300 | 11 | 19 |
Because HEB beams are heavier, they are often selected for projects requiring higher structural strength.

Why Choose S355J2 Instead of S355JR?
One of the most important differences between S355JR and S355J2 is the impact testing temperature.
| Steel Grade | Impact Test Temperature | Impact Energy |
|---|---|---|
| S355JR | +20°C | ≥ 27 J |
| S355J2 | -20°C | ≥ 27 J |
This means S355J2 H beams maintain excellent toughness even at sub-zero temperatures.
Why This Matters
Low-temperature toughness prevents brittle fracture, which is a critical safety concern in structural engineering.
Projects that typically require S355J2 steel beams include:
- Wind turbine towers
- Offshore structures
- High-altitude construction projects
- Northern European infrastructure
Because of this property, S355J2 H profile steel is widely specified by European structural engineers.
Production Process and Quality Control
The reliability of structural steel depends heavily on strict manufacturing and testing procedures.
Our S355J2 H beams are produced through:

What is the difference between S355JR and S355J2?
S355JR steel has a minimum impact strength of 27 J under 20-degree temperature conditions while the second type of steel, S355J2+N has the same impact strength but with a temperature of -20 degrees.
What material is S355 j2?
S355J2 is a medium tensile, low carbon manganese steel which is readily weldable and possess good impact resistance (also in sub-zero temperatures). This material is commonly supplied in the untreated or normalized condition. Machinability of this material is similar to that of mild steel.
What type of steel is S355J2?
S355J2 is a micro alloyed structural steel suitable for e.g. mechanical engineering applications. The steel posess a good weldability with max CEV =0.47 for all variants. The steel may be delivered with a controlled silicon content for good galvanazing properties.
What is the equivalent of S355 J2?
The equivalent of S355J2 EN 10025-2 is ASTM A572 Grade 50, DIN ST52-3, JIS SM490YA, and GB Q355D, with similar high strength and low-temperature toughness for structural use.
