News - Advantages and Disadvantages of Steel Structure

Steel structure is a structure mainly made of steel and is one of the main Structural Steel Fabrication. Steel is characterized by high strength, light weight and high rigidity, so it is particularly suitable for building large-span, ultra-high and ultra-heavy buildings.

Advantages of Steel Construction:
1. Good seismic resistance
2. The total weight of the building is light
3. The project cost is low (about 90 per person per person than traditional buildings) 4. The construction speed is fast
5. Good environmental protection effect (recyclable, reused, reducing waste)
6. Improve the area utilization rate (the area utilization rate can be improved by reducing the cross-sectional area of the columns and using lightweight wall panels, and the indoor effective use area increases by about 6%.)

Disadvantages of Warehouse Building:
1. Poor fire resistance
2. Poor corrosion resistance
3. Unique cold bridge problem (the north is an area where the "M cold bridge" phenomenon occurs frequently. Because the weather in the north is relatively cold in winter and the temperature difference between indoor and outdoor is large, the cold air enters the house and combines with the hot air to form water mist adsorbed on the wall. body, the house will become damp and mildewy)
4. The current domestic design and manufacturing levels are low. (China’s steel structure still has a long way to go due to defects in steel performance and quality)
5. Poor thermal insulation effect
6. Easy to produce distortion
Steel reinforced concrete structure is a combination of steel structure and reinforced concrete structure. It is the most commonly used building structure in Japan.

Prefabricated Building Steel Structure is an engineering structure made of steel and steel plates through welding, bolting or riveting. Compared with other constructions, it has advantages in use, design, construction and comprehensive economics. It has low cost and can be moved at any time. Features.

Structures Building residences or factories can better meet the requirements for flexible separation of large bays than traditional buildings. By reducing the cross-sectional area of columns and using lightweight wall panels, the area utilization rate can be improved, and the indoor effective use area can be increased by about 6 %.

The energy-saving effect is good. The walls are made of lightweight, energy-saving and standardized C-shaped steel, square steel, and sandwich panels. They have good thermal insulation performance and good earthquake resistance.

Using the Warehouse Steel Structure system in residential buildings can give full play to the good ductility and strong plastic deformation ability of the steel structure, and has excellent earthquake and wind resistance, which greatly improves the safety and reliability of the residence. Especially in the case of earthquakes and typhoons, steel structures can avoid collapse damage of buildings.
The total weight of the building is light, and the steel structure residential system is light in weight, about half that of the concrete structure, which can greatly reduce the foundation cost.

The construction speed is fast, and the construction period is at least one-third shorter than 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. The amount of sand, stone and ash used in the construction of steel structure residential buildings 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 and will not cause garbage. .
With flexibility and abundance. With a large bay design, the indoor space can be divided in multiple ways to meet the different needs of users.

Meet the requirements of residential industrialization and sustainable development. Steel structures are suitable for mass production in factories and have a high degree of industrialization. They can integrate advanced finished products such as energy saving, waterproofing, heat insulation, doors and windows, and apply them in complete sets, integrating design, production, and construction to improve the level of the construction industry.
