Performance characteristics of H-shaped steel

H-shaped steel is a new type of economic building steel. The cross-sectional shape of H-shaped steel is economically reasonable, with good mechanical properties. During rolling, the extension of each point on the section is relatively uniform and the internal stress is small. Compared with ordinary I-shaped steel, it has the advantages of large cross-sectional modulus, light weight, and metal saving, which can reduce the weight of building structures by 30-40%; Due to the parallel inner and outer sides of its legs and the right angled leg ends, it can be assembled into components, saving up to 25% of welding and riveting work.

The design style of hot-rolled H-beams is flexible and rich. Under the same beam height, the spacing of steel structures can be 50% larger than that of concrete structures, making the building layout more flexible. 

The construction speed is fast, the land area is small, and it is suitable for all-weather construction, with little impact from climate conditions. The construction speed of steel structures made of hot-rolled H-beams is about 2-3 times that of concrete structures, and the turnover rate of funds is doubled, reducing financial costs and thus saving investment.

The steel structure of hot-rolled H-shaped steel is scientifically reasonable, with good plasticity and flexibility, high structural stability, and is suitable for building structures that withstand large vibration and impact loads. It has strong resistance to natural disasters and is particularly suitable for building structures in earthquake prone zones.
