Portal frame

Portal frame is a traditional structural system, and the upper main frame of this type of structure includes inclined beams, columns, supports, purlins, tie bars, and gable frames.

The steel structure of portal frame lightweight buildings has the characteristics of simple stress, clear transmission path, fast component production, easy factory processing, and short construction period. Therefore, it is widely used in industrial and civil buildings such as industrial, commercial, and cultural entertainment public facilities.

The steel structure of portal frame lightweight buildings is a branch of lightweight steel structures. The main characteristics of this structural type are: reflecting the lightweight characteristics of lightweight steel structures, applying energy-saving and environmentally friendly new building materials, achieving factory processing and production, on-site construction assembly, convenience, and saving construction period; Reasonable structure, novel and beautiful building appearance, and obvious economic benefits; The size arrangement of the column grid is free and flexible, and can meet the construction and usage requirements under different climatic and environmental conditions.

The main application range of portal frame lightweight building steel structures, including single-story industrial and construction factories, civil construction markets and exhibition halls, warehouses, and various types of warehousing industrial and civil buildings, is its strong competition and has a wide range of market application prospects.

Portal frames can be divided into single span, double span, multi span frames, as well as frames with eaves and adjacent roofs according to their structural types.
