Properties of UB 686x254x140/152 h shaped steel beam
Cross-sectional area: The weight of the two is different, and the cross-sectional area is also different. The UB 686x254x152 h type beam has a larger cross-sectional area.
Moment of inertia and section modulus: These values determine the ability of the steel beam to resist bending, and UB 686x254x152 h type steel beam has better performance.
Radius of gyration: It affects the stability and stiffness of the steel beam.
Application areas of UB 686x254x140/152 h shaped iron beam
This type of steel has high load-bearing capacity and good welding performance, and is widely used in: bridge construction; large-span building frames; main structural support of industrial plants; core tubes and outer frame columns of high-rise buildings.
