H-shaped steel functions: supporting structure, structural profiles, grating floors, railings, overpasses and work platforms, cable distribution racks, tool handles, substation structures, etc.

American standard H-shaped steel beams are widely used in buildings or other metal structures. The cross-sectional dimensions of ordinary I-beams and light I-beams are relatively high and narrow, so the difference in inertia moments between the two main sleeves of the cross-section is significant, which limits their application. H-shaped steel should be selected according to the requirements of the design drawings

American standard H-shaped steel execution standard: ASTM standard, American standard H-shaped steel has three main quality grades such as A36, A572, A992, etc. For example, A36 and A572 materials represent carbon structural steel, while A992 is a low alloy steel. The American standard H-beam is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength to weight ratio. It is named after the same section as the English letter "H". Due to the fact that all parts of H-beam are arranged at right angles, H-beam has advantages such as strong bending resistance, simple construction, cost savings, and light structural weight in all directions, and has been widely used.

Due to the better comprehensive mechanical properties of the normalized workpiece compared to the annealed state, for some ordinary structural parts with low stress and performance requirements, normalizing can be used as heat treatment to reduce processes, save energy, and improve production efficiency. In addition, for some large or complex shaped parts, when there is a risk of cracking during quenching, normalizing can often replace quenching and tempering treatment as heat treatment.
