Can steel structure buildings replace traditional buildings?

The steel structure building is a sustainable building, which can be likened to building a house like producing mobile phones, and putting different parts on the assembly line of the factory for production. The "building parts" of steel structures, doors and windows, and light bulbs produced according to the standards are transported to the construction site for modular assembly, which will surpass the history of nearly a hundred years of construction and change the traditional building mode.

1. 10 times construction safety (100% quality assurance)

Compared with the traditional buildings, the steel structure components are manufactured by the factory with high precision charge in the early stage, and the product production is controlled by high-tech production equipment. The on-site construction is mechanized to reduce the error of manual operation, ensure the quality and ensure the construction safety. Moreover, the construction efficiency is improved 4-5 times.

2. More space (1/3 of the building weight)

The steel structure building wall gives full play to the comprehensive advantages of steel and concrete. There are fewer protruding columns and fewer walls. Compared with traditional buildings, the building weight is reduced by 2/3. The layout of indoor lightweight non load-bearing walls can be changed at will, and the decoration is more casual.

3. Short construction period (1/4 of the construction period)

As the steel structure components are produced according to the specifications in the factory and assembled on site, the construction is not affected by the weather. The floor slab adopts fabricated steel bar truss self-supporting floor slab, which can be constructed in multiple layers at the same time to achieve vertical cross operation, and the construction speed is faster. Three floors a day saves 3/4 of the construction period compared with traditional buildings.

4. More anti-seismic (Grade 9 anti-seismic)

The roofs of low rise villas are mostly sloping roofs, so the layer structure is basically a triangular roof truss system made of cold-formed steel members. After sealing structural plates and gypsum boards, light steel components form a very solid "plate rib structure system". This kind of structure system has stronger seismic resistance and resistance to horizontal loads, and is suitable for areas with seismic intensity above 9.

5. 93% factory (1/10 field work)

The work on the construction site shall be done in the factory, the outdoor work shall be done indoors, and the horizontal construction planning and site setting out shall be done by computer. 85%~95% of the components can be processed in the factory, reducing the number of workers by about 60% compared with the traditional construction site. At the same time, it is easy to remove, the parts and products can be reused, and the materials can be recycled. In the future, more parts such as wallboards and staircases will be delivered to the construction site instead of scattered reinforcement, concrete and insulation boards. With the cooperation of machinery, workers assemble these parts into houses.

6. Better thermal insulation performance

The steel structure building has light weight, high strength, good overall rigidity and strong deformation capacity. The deadweight of the building is only one fifth of that of the brick concrete structure, which can withstand the hurricane of 70 meters per second, so that life and property can be effectively protected.

7. 1% of construction waste (green buildings)

Traditional buildings produce 200 kilograms of garbage per square meter, and a 50000 square meter building emits about 10000 tons of garbage.

8. More environmental protection (green buildings)

Steel structure workshop, warehouse, steel structure residence and steel structure villa are made and installed with steel structure. The materials used are mainly 100% recycled or degraded materials, which will not become garbage pollution when the buildings are demolished.

9. Better sound insulation

The sound insulation effect is an important indicator for the evaluation of residential buildings. The windows installed in the light steel system are all made of insulating glass, which has a good sound insulation effect of more than 40 decibels. The wall composed of light steel keel and thermal insulation material gypsum board has a sound insulation effect of up to 60 decibels. Health: dry construction can reduce the pollution of waste to the environment. The steel structure materials of the house can be 100% recycled, which conforms to the current environmental awareness. All materials are green building materials, which meet the requirements of ecological environment and are conducive to health.

10. Durability

The light steel structure villas are all composed of cold-formed thin-walled steel member systems. Effectively avoid the impact of corrosion of steel plates in construction and use, and increase the service life of light steel components, with the structural life up to 100 years.
