Truss Roof Steel Structure Warehouse Construction Metal Truss Fabrication
Steel truss roof is one kind of structure consisting of rods connected by hinges at each end. Trusses are generally planar or spatial structures composed of straight bars with triangular elements. The members of trusses are mainly subjected to axial tension or pressure, so as to make full use of the strength of materials. When the span is large, it can save materials, reduce the dead weight and increase the stiffness compared with the real web beam.
We disign the drawing, fabricate all the steel columns, beams, purlin, ect, install the steel structure and panel, window&doors for our client.
