Steel Portal Frames

Portal Steel Frame Buildings is the most common structure system. It widely used in light steel buildings such as warehouses, workshops, sheds, garages.
The portal steel frame is a lightweight building system; it is a solid web or lattice portal frame as the main load-bearing framework, composed of welded H-shaped (equal or variable cross-section), hot-rolled H-shaped steel, or cold-formed thin-walled steel. Cold-formed thin-wall steel (C or Z-shaped) use as purlins and wall girt; corrugated metal sheets are used for roofs and walls; use polystyrene foam, rigid polyurethane foam, rock wool, mineral wool, glass wool, etc., as heat preservation and heat insulation materials, and appropriately set up bracing system.
Compared with the reinforced concrete structure. The portal steel frame has the advantages of a lightweight, high rigidity, flexible design, reasonable force, and convenient construction.
