Multi Floors Steel Frame Office Buildings / Prefab Steel Structures Buildings
Multi Floors Steel Frame Office Buildings / Prefab Steel Structures Buildings. The major structure of this three floors is consisted of welded H-section steel beam and column. Glavanized steel floor decks is used to support floor concrete. Connection of the steel frame structure is by bolts.
The steel structure building has the advantages of wide span, high strength, light weight, low cost, temperature protection, save energy,beautiful appearance, short construction time, good effect of insulation, long using life, space-efficient, good seismic performance, flexible layout,etc.
