Materials and components: It is mainly made of steel and steel plates connected or welded into components, and then connected and welded. Commonly used

sections include I-beams, channel channels, angle steels, etc., while steel plates are used to make various nodes and components

Structural form: Steel frame structures and steel frame-concrete core tube structures are mostly used. The latter is widely used, using concrete core tubes to

provide strong lateral force rigidity, and steel frames to bear vertical loads and part of horizontal loads1.

Product Advantages

High strength and light weight: Steel is much stronger than traditional building materials such as concrete and masonry. Therefore, steel structures can withstand greater loads while being relatively light in weight. This allows the construction of high-rise buildings to reduce the bearing pressure of the foundation and reduce the cost of infrastructure construction. When natural disasters such as earthquakes occur, the seismic force suffered by the structure is relatively small, which is conducive to improving the seismic performance of the building.

Good earthquake resistance: Steel has good toughness and ductility, and can produce large deformation under earthquake action without sudden damage. Steel structure high-rise buildings can absorb and dissipate earthquake energy through their own deformation, thereby effectively reducing earthquake damage to buildings and protecting the safety of people and property in buildings.

Product Application

Commercial buildings Large-scale shopping centers: For example, Shanghai's Wujiaochang Wanda Plaza uses steel structural frames to provide long-span space and meet the needs of flexible layout of commercial space. It can be freely divided and combined according to the requirements of different merchants to create diversified shopping environment. At the same time, the rapid construction characteristics of steel structures shorten the construction cycle of shopping centers, allowing them to open and operate faster and attract consumers. Commercial complex: Take Shenzhen Ping 'an Financial Center as an example. It integrates office, commerce, hotel and other functions. The application of steel structures enables them to achieve complex architectural shapes and ultra-large building scales, integrate multiple commercial formats in limited urban space, become a commercial landmark of the city, and drive regional economic development.
