Building Description
Commercial steel structure buildings are formed by the main framework through linking up H beams, C purlins, and Z purlin steel components. Roof and wall systems use various panels together with other components such as windows and doors. These buildings offer wide span capabilities, high strength, light weight, low cost, temperature protection, energy efficiency, attractive appearance, short construction time, excellent insulation, long service life, space efficiency, good seismic performance, and flexible layout options.
