For customers who don't know much about steel grating, there is no difference between steel grating flat steel and I-beam. In fact, steel grating flat steel does not belong to I-beam. The cross section of I-beam resembles the Chinese character "I", so it is called I-beam. However, it should be noted that there are many differences between I-beam and H-beam, such as:
1. There are hot-rolled I-beams and hot-rolled H-beams. Only welded H-beams, no welded I-beams.
2. The meaning of I-beam does not include H-beam. They are two types of sections.
3. The two outer sides of the H-beam have no slope and are straight. This makes the welding and splicing of H-beams easier than I-beams, and has better mechanical properties per unit weight, which can save a lot of materials and construction time.
4. The rolling mill of H-beam is a special rolling mill, which is different from rolling I-beam.
