Both ordinary and light I-beams have the characteristics of narrow flange and high web. The shape is like a tall and thin "I" word as its name, but the flange and web are not as vertical as the word, but there is radian. This feature also makes the performance of its two main shafts have a gap, which is not a good phenomenon. It not only limits the scope of application of I-beam, but also makes it easy to produce imbalance. How can the performance of steel structure buildings be guaranteed if the stability is not guaranteed.
H-beam can be said to be the evolution of I-beam. It improves the unreasonable section shape of I-beam, lengthens the flange and makes it perpendicular to the web, which makes it resistant to the forces from both sides, the section performance is more stable, and the bearing capacity has been significantly improved. Under the same load-bearing conditions, the steel consumption of H-section steel is less than that of I-beam, saving production cost.
The specifications of H-section steel are complete and can meet various design requirements. Its accurate specifications also make it more closely connected with other structures, the integrity of steel structure is stronger and more stable, and it can be more stable in the face of strong wind or earthquake..
