h beam
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
