What Are The Differences Between I-Beams And H-Beams – Tianjin Ehong International Trade
1.What are the differences between I-beam and H-beam？
（1） It can also be distinguished by its shape. The cross section of I-beam is “工”, while the cross section of H-beam is similar to the letter “H”.
（2） Due to the small thickness of I-beam steel, careful observation of the flange of I-beam steel is narrow, the closer to the web the thicker, so it can only withstand the force from one direction, H-beam thickness is larger, and the flange thickness is equal, so it can withstand the force in different directions
（3） I beam is suitable for all kinds of buildings, the application range of curved members in the plane is very limited. H-beam steel is used in industrial and civil building steel structure beam, column members, industrial steel structure bearing Support, etc.
（4） The flange of H-beam steel is of equal thickness, with rolled section and combined section composed of 3 plates welded. I-beams are rolled sections, because of poor production technology, the inner edge of the flange has a 1:10 slope. Unlike ordinary I-beams, H-beams are rolled with one set of horizontal rolls,Because the flange is wide and has no inclination (or is very small), it is necessary to add a set of vertical rolls to roll at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mill.
2.how to see whether it is inferior steel？
（1）Fake and inferior steel is easy to fold If it is inferior steel, it is easy to be bent, making the steel lose its original shape. The main reason for this is that manufacturers blindly pursue high efficiency, the amount of pressure is large, resulting in a decline in product strength, it is easy to be bent.
（2）The appearance of shoddy steel often has uneven surface phenomenon The surface of inferior steel often appears uneven phenomenon, mainly because of groove wear caused , so we should carefully look at whether the surface has this defect when choosing.
（3）The surface of shoddy steel is prone to scarring
Usually, poor quality steel is prone to impurities, the surface is easy to scar, so from this point it is easy to tell the quality of the steel is good or bad.
（4） Fake and inferior steel is easy to scratch
Many manufacturers of production equipment is simple, production technology is not up to standard, so the production of steel surface will produce burrs, and steel strength is not up to standard, if this kind of steel do not buy.
