The cross-section shape of i beam steel is i beam, with long legs on both sides of the cross-section and a short leg in the middle, so it is called i beam steel. 

The cross-sectional shape of i beam steel makes it have high strength and stiffness, and can withstand larger loads. The i beam steel has a reasonable shape design, which can provide greater bending stiffness and shear stiffness, ensuring the stability and safety of the structure. The connection methods of i beam steel are flexible and diverse, and can be connected to other components through welding, bolting, etc., to facilitate construction and disassembly. i beam steel has good plasticity and can adapt to various complex mechanical environments, improving the seismic resistance and reliability of the structure.

i beam steel: Common specifications include I20, I25, I30, I40 and other models, which are suitable for situations with smaller spans and smaller loads.
