Features of Automobile Bottom Beam
1, The bottom beam of the car is made of hot-rolled H-beam. Hot-rolled H-beam has strong quality because of one-time hot-rolling forming, and there are no numerous 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, high performance and brief delivery time.
3, The steel structure of H-beam is high in strength. Compared with I-beam, the section modulus is massive. When the bearing conditions are the same, it could keep 10-15% of metal.
4, The structure is scientific and reasonable, with good plasticity and flexibility, excessive structural stability, and can resist large vibration and effect loads
5, Save labor and material, compared with welding H-beam, it could obviously save labor and material, lessen the consumption of raw materials, energy and labor, low residual stress, and good appearance and surface quality.
