Q345 Steel H Beam

Q345 steel H-beam is a low alloy steel with a yield strength of 345MPa, a tensile strength of 470-630MPa, an elongation of ≥20%, and high strength, plasticity and welding performance. It is widely used in industrial and civil steel structure beams and columns, as well as petrochemical, power equipment and bridges. It has a large section modulus, light weight, metal saving, simple assembly, less welding, strong wind resistance, good stability, and is suitable for high-rise and windy area buildings. Compared with Q235, it has higher strength and adapts to more complex loads.
