Advantages and disadvantages of Nanjing steel structure

Updated: 2019-11-21 15:01:29
Nowadays, the competition in the steel structure construction industry is getting more and more intense, so now steel structure construction companies pay more and more attention to quality and service. Nanjing steel structure manufacturers tell everyone to pay attention to the choice of steel structure. In important industrial structures such as heavy industrial buildings, large-span, high-rise or super-high-rise civil structures, consideration should be given to the use of high-quality steel structures. For general industrial and civil building structures, ordinary quality steel structures can be selected according to the nature of the work. Effectively reduce costs on the basis of ensuring safe use.
For structures that directly support dynamic loads and structures in strong earthquake areas, steel structures with good comprehensive performance should be selected; for structures that generally support static loads, Q235 steel can be selected. The welding process will produce welding deformation, welding stress and other welding defects, which may lead to the risk of cracks or brittle fracture of the structure. Therefore, the material requirements of the welding structure should be stricter. Steel structures are easily cold and brittle at low temperatures, so structures that work under low temperature conditions, especially welded structures, should be selected from steels that have good resistance to low temperature brittle fracture. In addition, the steel structure of the open-air structure and the steel structure under the influence of the harmful medium environment are susceptible to corrosion, fatigue and fracture. Different materials should also be selected and the anticorrosive work should be done well.

The thin steel structure has many rolling times, the rolling compression ratio is large, and the thick steel structure has a small compression ratio. Therefore, a thick steel structure not only has low strength, but also has poor plasticity, impact toughness, and welding performance. Therefore, the welding structure with a large thickness should use a better steel structure. Steel structure platforms are usually composed of planks, primary and secondary beams, columns, inter-pillar supports, and stairs and railings. They can be used indoors or outdoors, platforms that support static and dynamic loads, production auxiliary platforms, and medium and heavy operating platforms. The steel structure is light and strong, and is suitable for large-span and ultra-high and ultra-heavy buildings.
Steel structural materials have uniform properties, good toughness and elasticity, and can withstand dynamic loads well. It meets the basic assumptions of general engineering mechanics and is an ideal building material today. The short construction period saves time and cost and creates more value for the enterprise. Steel structure engineering has a high degree of industrialization, which guarantees work efficiency and quality. At the same time, it reduces construction difficulty and saves labor. Steel structure also has disadvantages, that is, the fire resistance and corrosion resistance are poor, so fire and corrosion protection work must be done well.
