H-beams, also known as Universal Columns (UC), Wide Flange Beams (W-Beam), Universal Beams (UB), Rolled Steel Joists (RSJ), or Double-T beams (commonly used in European languages), are structural members characterized by an H-shaped cross-section.

The horizontal parts are called flanges, while the vertical part is the web. Owing to this design, H-beams offer excellent load-bearing capacity, making them essential in building construction, civil engineering, machinery manufacturing, bridges, industrial plants, and more.
Among many steel grades, Q235 H-Beams are one of the most widely used options due to their cost-effectiveness, weldability, and stable mechanical properties, especially in light to medium-duty structural applications.

FAQs – Q235 H-Beams Compared with Other Products
1. What is the difference between Q235 H-Beam and Q355 H-Beam?
Q235: Yield ≥ 235 MPa
Q355: Yield ≥ 345 MPa
Difference:
Q355 is stronger and suitable for heavy-duty and high-demand structures.
Q235 is more cost-efficient and suitable for light to medium-duty applications.
If budget-sensitive → choose Q235.
If strength-critical → choose Q355.
2. Is Q235 the same as S235JR?
Yes, Q235 ≈ S235JR in mechanical properties and chemical composition.
Both belong to low-carbon structural steels used for similar applications.
3. How does Q235 H-Beam compare with Corten Steel H-Beam?
| Feature | Q235 H-Beam | Corten Steel H-Beam (Weathering Steel) |
|---|---|---|
| Corrosion Resistance | Low | Very High |
| Maintenance | Requires paint/coating | Minimal / No painting needed |
| Strength | Standard | Higher strength and durability |
| Cost | Cheaper | More expensive but long-term savings |
| Application | General construction | Outdoor, bridges, architectural façades |
If long-term outdoor use without painting → choose Corten H-beam.
4. Is Q235 H-Beam good for welding?
Yes.
Q235's low carbon content ensures:
Smooth welding
Low risk of cracking
No need for special welding rods
It is one of the most welder-friendly steels.
5. Can Q235 H-Beam be galvanized?
Yes.
Hot-dip galvanizing can improve its corrosion resistance.
