Made in China High Quality Steel Structure Multi-layer Frame Building Materials
The steel structure multi-storey building uses steel as the main support structure, and with the characteristics of high strength and good toughness of steel, it builds a stable and flexible space. Its frame is made of steel beams and steel columns closely connected by welding or bolts, which can efficiently carry the self-weight of the floor and various live loads, even in the face of strong winds, earthquakes and other external forces, it can also effectively absorb energy with good ductility and ensure the safety of the building. The profiled steel plate not only provides a template for concrete pouring, but also works with the concrete to enhance the overall bearing capacity of the floor. The exterior wall is made of lightweight metal curtain wall panels or sandwich panels, which not only reduces the weight of the building, but also has good thermal insulation, thermal insulation and waterproof performance. Due to the advantages of the large span of the steel structure, the internal space can be flexibly separated to meet the needs of office, commercial, residential and other multiple functions.

Product Advantages:
The steel structure multi-storey building has great advantages in the selection of materials, providing strong support for the quality and performance of the building from multiple dimensions. In terms of main structural materials, H-beam can efficiently carry vertical and horizontal loads by virtue of its reasonable aspect ratio and excellent cross-sectional mechanical properties, greatly reducing the space occupied by the structure and increasing the usable area inside the building. Although the inner surface of the I-beam has a slope, the bending performance can be fully exerted in the parts where the lateral stiffness requirements are not high, and the structural stress system can be optimized to reduce the steel cost. In the light steel truss and support system, the small amount of steel used in the light steel truss and support system greatly enhances the structural stability and improves the safety redundancy of the overall structure. The uniform cross-sectional stress and excellent torsional performance of the round steel pipe make it meet the design creativity in the unique shape of the building, ensure the stability of the structure, and broaden the architectural design possibilities.
The advantages of connection materials are outstanding. The high-strength bolts are easy to install, and the connection of steel structure components can be quickly completed on site, which improves the construction efficiency and is convenient for later maintenance and disassembly. The welding materials are accurately matched according to different steels to ensure that the performance of the welded joints is consistent with the base metal, so that the structure forms a solid whole and ensures the safety and reliability of the structure in long-term use.
The material advantages of the enclosure system are obvious. The steel plate is light in weight, which greatly reduces the weight of the building, reduces the foundation load, is convenient to install, and significantly shortens the construction period; High strength and excellent weather resistance make it resistant to wind and rain erosion for a long time, reduce maintenance costs, and enrich colors and shapes to give the building a unique appearance, enhancing the overall image and commercial value of the building. With different thicknesses and diverse core materials, sandwich panels have outstanding thermal insulation, heat insulation and sound insulation performance, effectively reduce building energy consumption, achieve warm in winter and cool in summer, and are used on building exterior walls and roofs, taking into account enclosure and energy saving, which is in line with the development trend of green buildings and reduces the impact on the environment.
