The width b ≅ 3 m, and the length l ≅ 4 m. The steel structure consists mainly of four transverse beams, two knee braces, two suspension rods, a longitudinal front truss, a frame, purlins, and metal roofing sheets. The canopy roof is connected to the reinforced concrete structure of the building. Figure 3 shows a schematic partial three-dimensional view of the structure.
