This modern pre-engineered metal building features a portal steel frame structure ideal for auto repair shops and maintenance facilities. The welded H-section steel columns and beams are connected with high-strength bolts, while glass wool sandwich panels provide roof and wall insulation. Available in clean span or double span configurations.
Prefabricated steel frame structures are widely used for factories, warehouses, workshops, office buildings, and more. The system combines H beams, columns, and purlins with various panels to create structures with wide spans, large interior spaces, and excellent seismic performance.
