Characteristics of car bottom beam

1, The backside beam of the automobile is made of hot-rolled H-beam. Hot-rolled H-beam has sturdy excellent due to the fact of one-time hot-rolling forming, and there are no severa shortcomings consisting of weld cracks and low fatigue resistance at welds.

2, The use of hot-rolled H-beams to produce beams has few processes, excessive overall performance and short transport time.

3, The metal shape of H-beam is excessive in strength. Compared with I-beam, the part modulus is massive. When the bearing prerequisites are the same, it ought to preserve 10-15% of metal.

4, The shape is scientific and reasonable, with properly plasticity and flexibility, immoderate structural stability, and can face up to massive vibration and impact masses

5, Save labor and material, in contrast with welding H-beam, it should needless to say retailer labor and material, reduce the consumption of raw materials, power and labor, low residual stress, and appropriate look and floor quality.
