Q345 Steel l Beam

Q345 steel I-beam is made of low alloy high strength structural steel Q345, with alloy elements such as manganese and silicon added, high yield strength, and better corrosion resistance than Q235. Its I-shaped cross-section design enhances its bending and torsion resistance and is widely used in large buildings, bridges, cranes and other high load-bearing structures as a key load-bearing component. The beam has high strength and good stability, is suitable for complex stress environments, and is an ideal choice for heavy-load structures.
