  ms.grade jis g3101 ss400/sm490  hot rolled h beams iron for sales

  h beam  shape

Cross section shape reasonable in economy, and mechanics performance is good, rolling in cross section of different points on extension is more homogeneous internal stress is small, and ordinary i-steel comparison, has the cross section modulus big light weight save metal advantages, can make the building structure reduce 30-40%; And because of its leg inside and outside parallel, leg end is square, go all out outfit combination into components, can save welding riveting workload 25% often used for bearing cut capacity, cross section stability good large building (such as building high-rise building, etc.), as well as the bridge ship lifting the transport machinery equipment foundation support foundation pile, and so on
