What is the difference between I-beam and H-beam?

　　1. What is the difference between I-beam and H-beam?

　　1. Different properties

　　The cross-section of I-beam is I-shaped, and the cross-section of h-beam is the same as the English letter H, and the strength-to-weight ratio of h-beam is more suitable for economical steel.

　　2. Different classifications

　　I-beams are ordinary I-beams. H-shaped steel can be divided into wide flange, medium flange and narrow flange according to product classification.

　　2. What should you pay attention to when purchasing steel?

　　1. When purchasing steel, pay attention to the structural part of the steel. Be sure to note that there are many types of steel. When purchasing steel, you can choose steel of appropriate quality according to your actual situation.

　　2. When choosing steel, you need to make certain judgments about the structural environment. When working at low temperatures, the structure needs to be welded. You can choose some low-temperature-resistant killed steel. This kind of steel will not show any deformation after being exposed to low temperatures, let alone Some environmental problems lead to corrosion of steel.

　　3. You can choose high-temperature-resistant steel, because this kind of steel can withstand a certain high temperature in the middle and will not cause the steel to be deformed or corroded in a high-temperature environment.

　　4. When choosing steel, go to regular manufacturers. Don't be greedy for small gains and choose some inferior products. This is also a very irresponsible behavior for our buildings.
