I-Beam

I-beam steel is a type of hot-rolled long steel with an I-shaped cross-section, consisting of parallel upper and lower flanges connected by a vertical web, forming an efficient mechanical structure. Based on flange width, it is classified into standard I-beams (e.g., I20a) and wide-flange H-beams (e.g., HW200×200). Specifications are expressed as web height × flange width × web thickness (e.g., I250×116×8). Its unique cross-sectional design provides good bending resistance and structural stability in the vertical direction while maintaining a relatively light weight horizontally. The material distribution aligns with engineering mechanics principles. I-beam steel is primarily used in load-bearing scenarios such as main beams in building structures, columns in industrial buildings, and bridge frameworks. It can also be combined to form larger load-bearing assemblies. As a key load-bearing component in steel structure engineering, it offers high load efficiency, convenient installation, and good cost-effectiveness.
