Steel members refers to  useing  steel plate, Angle steel, channel steel, i-steel, welding or hot-rolled h-beam welding by cold bending or fittings connected can bear and transfer load combination of steel structure components, 
Steel members system advantage：
  1.Light weight,
  2.Factory manufacturing,
  3.Fast installation,
  4.The construction period is short,
  5.the seismic performance is good,
  6.Investment recovery fast,
  7.Recyclable
   
Technical indicator:

1.The steel structure method: welding connection
2.Steel structure design norms:
"Steel Design Code" (GB50017-2003) 
"Cold-formed steel structure technical specifications" (GB50018-2002)
