Difference of H beams:
It is a kind of steel with better mechanical properties developed from h-shaped steel. It is named because its cross-section is the same as the English letter "H". H-shaped steel is divided into "wide flanged steel (HW), middle flanged H-shaped steel (HM), narrow flanged H-shaped steel (HN), thin-walled H-shaped steel (HN), thin-walled H-shaped steel (HT), H-shaped steel (HU)."
H-shaped steel is a new type of steel for construction. The cross-sectional shape is economical and reasonable, and the mechanical properties are good. During rolling, the points on the cross-section extend more uniformly and the internal stress is small. The advantages of steel can reduce the building structure by 30-40%. And because the legs are parallel to the inside and outside, and the legs are at right angles, they are assembled into a component, which can reduce the workload of welding and riveting by 25%. Commonly used in large buildings such as brackets, foundation piles, etc.
