Profile Steel I Beam Q235B

The cross-section shape of steel I beam is I-beam, which has high strength and stiffness and can withstand large loads and deformation, so it plays an important role in building structure.
The chemical composition of Q235B I beam steel is in accordance with the national standard, and it has good weldability and processability, which can meet the needs of various construction projects. In addition, the surface of Q235B I-beam is smooth without obvious defects, which can ensure the beauty and safety of the building structure.
Why Choose Q235B I-Beam?
1. Superior Mechanical Properties
Property | Value |
---|---|
Yield Strength | ≥235 MPa |
Tensile Strength | 370–500 MPa |
Elongation | ≥26% |

2. Cost-Effective Structural Solution
Compared to high-alloy steels (e.g., Q345B), Q235B reduces material costs by 15–20% without compromising structural integrity for moderate-load applications.
3. Easy Fabrication & Welding
The low carbon content (0.12–0.20%) ensures excellent weldability, cutting, and bending performance, minimizing fabrication time and labor costs.
4. Corrosion Resistance
Optional galvanizing (275 g/m² coating) extends service life in humid or corrosive environments.
