Steel structure workshop is the type of building formed by main framework which mainly consists of steel column, steel beam and purlin, thus the steel structure accounts for the major load-bearing member of steel workshop building. The roof and wall of steel workshop utilize various styles of panels that will overlap when assembled together, leaving no openings. As a result, the steel frame workshop can be isolated against outdoor environments. Due to reasonable cost and short construction period, steel structure has been applied in a wide range of industrial and non-industrial building construction.
