Compared to traditional buildings, steel structure buildings represent a modern approach—where the entire building is constructed using steel. This structure mainly consists of steel beams, columns, trusses, and other components made from section steel and steel plates. The individual parts are connected through welding, bolts, and rivets. Thanks to their lightweight and streamlined design, steel structures are commonly used in large factories, stadiums, skyscrapers, and other sectors. The common types of steel building structures include portal rigid steel frames, frame structures, truss structures, and grid structures.Portal Frame Structure: This structure is simple in terms of load distribution, with a clear force transmission path, and it allows for rapid construction. It is commonly used in industrial and civil buildings, including commercial, cultural, and entertainment facilities.Steel Frame Structure: The steel frame structure offers flexibility and allows for larger open spaces, making it ideal for multi-story and high-rise buildings such as office complexes, shopping malls, conference centers, and similar structures.Steel Truss Structure: Composed of small cross-sectional tubes arranged to form larger components, the steel truss structure is typically used in buildings requiring large spans or significant height, such as large-span roofs, bridges, towers, and offshore oil platforms.Steel Grid Structure: This type of structure is a highly indeterminate spatial framework made of interconnected rods, which provides minimal space stress, lightweight construction, high rigidity, and excellent seismic resistance. It is suitable for applications such as sports arenas, exhibition halls, petrol stations, and aircraft hangars.
