Products Information

Steel portal frame has the characteristics of simplicity of load-carrying, clear force transmission path, fast components production, short construction period, durable and novel structure and aesthetic appearance etc.

Steel portal rigid frame mainly used in single plant, supper market, exhibition halls, warehouse, commercial & culture and entertainment public facilities etc.

Portal frame construction is a method of building and designing structures, primarily using steel or steel-reinforced precast concrete although they can also be constructed using laminated timber such as glulam. The connections between the columns and the rafters are designed to be moment-resistant, i.e. they can carry bending forces.
Because of these very strong and rigid joints, some of the bending moment in the rafters is transferred to the columns. This means that the size of the rafters can be reduced or the span can be increased for the same size rafters. This makes portal frames a very efficient construction technique to use for wide span buildings.
Portal frame construction is therefore typically seen in warehouses, barns and other places where large, open spaces are required at low cost and a pitched roof is acceptable.
Generally portal frames are used for single story buildings but they can be used for low rise buildings with several floors where they can be economic if the floors do not span right across the building (in these circumstances a skeleton frame, with internal columns, would be a more economic choice). A typical configuration might be where there is office space built against one wall of a warehouse
