1. Earthquake resistance
Most of the roofs of low rise villas are sloping roofs, so the roof structure basically adopts the triangular roof truss system made of cold-formed steel members. After sealing the structural plates and gypsum boards, the light steel components form a very strong “plate rib structure system”. This structural system has stronger seismic resistance and horizontal load resistance, and is suitable for areas with seismic intensity above 8 degrees
2. Wind resistance
Light steel structure building is light in weight, high in strength, good in overall rigidity and strong in deformation. The self weight of the building is only one fifth of that of the brick concrete structure. It can resist the hurricane of 70 meters per second, so that life and property can be effectively protected
3. Durability
The light steel structure residential structure is composed of cold-formed thin-walled steel member system, and the steel skeleton is made of super anticorrosive high-strength cold-rolled galvanized sheet, which can effectively avoid the influence of corrosion of steel plate in the process of construction and use, and increase the service life of light steel components. The service life of the structure can reach 100 years
4. Thermal insulation
The thermal insulation material is mainly glass fiber cotton, which has good thermal insulation effect. The insulation board of external wall can effectively avoid the “cold bridge” phenomenon of the wall, and achieve better thermal insulation effect. The thermal resistance value of R15 thermal insulation cotton with a thickness of about 100 mm can be equivalent to a brick wall with a thickness of 1 m
5. Sound insulation
The sound insulation effect is an important index to evaluate the residential buildings. The windows installed in the light steel system are all made of insulating glass, which has good sound insulation effect, and the sound insulation effect is more than 40 db; the wall composed of light steel keel and thermal insulation material gypsum board can achieve the sound insulation effect as high as 60 dB
6. Health
Dry construction can reduce the environmental pollution caused by waste. The steel structure materials of the house can be recycled 100%, and most of the other supporting materials can also be recycled, which is in line with the current environmental awareness. All materials are green building materials, which meet the requirements of ecological environment and are conducive to health
7. Comfort
The light steel wall adopts high-efficiency energy-saving system, which has breathing function and can adjust indoor air dry and humidity; the roof has ventilation function, which can form a flowing air room above the house, so as to ensure the ventilation and heat dissipation requirements inside the roof
8. Fast
The whole process from foundation to decoration can be completed by only 5 workers in 30 working days for a 300 square meter building
9. Environmental protection
Materials can be 100% recycled, truly green pollution-free
10. Energy saving
All adopt high efficiency energy-saving wall, the effect of heat preservation, heat insulation and sound insulation is good, which can reach 50% energy saving standard
