Q235 H-Beam and I-Beam are common structural steel sections widely used in construction and industrial engineering.
Made from Q235/Q235B carbon steel, they offer excellent weldability, good plasticity, and reliable load-bearing performance, making them one of the most economical steel choices for building frameworks, support columns, bridges, machinery manufacturing, and general structural applications.
What Are Q235 H-Beams & I-Beams?
H-beams and I-beams get their names from their cross-sectional shapes resembling the letters "H" and "I."
Each section consists of:
Web (waist): Vertical central plate
Flanges: Horizontal top and bottom plates
Q235 beams are produced according to Chinese standards (GB/T 700) and can be manufactured in hot-rolled or welded forms.

Advantages of Q235 H-Beams & I-Beams
1. Excellent Weldability
Low carbon content ensures easy welding with common electrodes, suitable for on-site construction and heavy fabrication.
2. Good Ductility and Toughness
High plasticity allows Q235 beams to withstand impact and deformation, improving safety in buildings and machinery structures.
3. Cost-Effective
Q235 is one of the most economical structural steels-ideal for large-volume projects such as warehouses, commercial buildings, and infrastructure.
4. Wide Range of Sizes
Available in both hot-rolled and welded sections from 100mm to 900mm height, suitable for light, medium, and heavy structural use.
