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.

We could design layout drawing,3D Tekla model, construction drawing as your request.

The floor space of our steel structre fabrication factory is 35,000㎡, and the workshop area is 20000㎡. We own three light/heavy H steel production lines, BOX production lines, C/Z purlin production lines and various types of profiling steel sheet machines with advanced equipment such as plasma cutting machine.
