What are the advantages of I-beams?
I-beam is an economical section steel with superior cross-sectional mechanical properties, characterized by the following:
Wide flanges and high lateral stiffness, resulting in strong bending resistance.
The parallel surfaces of the flanges make connection, processing, and installation convenient.
Compared with ordinary section steel, I-beams offer lower cost, higher precision, and reduced residual stress. They eliminate the need for expensive welding materials and weld inspection, saving approximately 30% in steel structure fabrication costs.
Under the same sectional load, hot-rolled H-beam structures are 15%-20% lighter than traditional structures.
