Comparison of advantages and disadvantages of steel structure building and concrete building


1. Steel structure is an engineering structure made of section steel and steel plate through welding, bolting or riveting. Compared with other constructions, it has advantages in use, design, construction and comprehensive economy, and the cost is low. Mobile characteristics.

2. Steel structure houses or factories can better meet the requirements of flexible partitioning of large bays in buildings than traditional buildings, and can increase the area utilization rate and increase the effective indoor area by reducing the cross-sectional area of the columns and using lightweight wall panels. About 6%.

  3. Good energy-saving effect. The wall adopts light-weight energy-saving standardized C-shaped steel, square steel, and sandwich panel, which has good thermal insulation performance and good earthquake resistance.

  4. The use of steel structure system in residential buildings can give full play to the good ductility of steel structure, strong plastic deformation ability, excellent seismic and wind resistance, and greatly improve the safety and reliability of residences. Especially in the event of an earthquake or typhoon disaster, the steel structure can avoid the collapse of the building.

  5. The total weight of the building is light, and the weight of the steel structure residential system is light, about half of that of the concrete structure, which can greatly reduce the basic cost.

  6. The construction speed is fast, and the construction period is at least one-third shorter than that of the traditional residential system. It only takes 20 days and five workers to complete a 1,000 square meter building.

   7. Good environmental protection effect. During the construction of the steel structure house, the amount of sand, stone, and ash is greatly reduced. The materials used are mainly green, 100% recycled or degraded materials. When the building is demolished, most of the materials can be reused or degraded without causing garbage .

   8. To be flexible and fruitful. With large bay design, the indoor space can be divided into multiple schemes to meet the different needs of users.

   9. Meet the requirements of residential industrialization and sustainable development. The steel structure is suitable for mass production in factories, with a high degree of industrialization, and can integrate advanced products such as energy saving, waterproofing, heat insulation, doors and windows, and complete sets of applications, integrating design, production, and construction, and improve the level of construction industry.
