Wind resistance
Steel structure has the advantages of light weight, high strength, good overall rigidity and strong deformation ability. The self weight of the building is only one fifth of that of the brick concrete structure, which can resist the hurricane of 70 meters per second, so that life and property can be effectively protected.
Earthquake resistance
Most of the roofs of low rise villas are sloping roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel members. After the structural plates and gypsum boards are sealed, the light steel members form a very strong "plate rib structure system". This structure system has stronger seismic resistance and resistance to horizontal loads, and is suitable for buildings with seismic intensity of 0 Areas above 8 degrees.
Sound insulation
The sound insulation effect is an important index to evaluate the residence. The windows installed in the light steel system are all made of insulating glass. The sound insulation effect is good, and the sound insulation is more than 40 dB. The sound insulation effect of the wall composed of light steel keel and thermal insulation material gypsum board can be as high as 60 dB.
Heat preservation
The thermal insulation material used is mainly glass fiber cotton, which has good thermal insulation effect. The thermal insulation board used for the external wall can effectively avoid the "cold bridge" phenomenon of the wall and achieve better thermal insulation effect. The thermal resistance of R15 insulation cotton with thickness of about 100 mm is equivalent to that of brick wall with thickness of 1 m.
Health
Dry construction can reduce the environmental pollution caused by waste. The steel structure materials of houses can be recycled 100%, and most of other supporting materials can be recycled, which is in line with the current environmental protection awareness. All materials are green building materials, which meet the requirements of ecological environment and are conducive to health.
Durability
The residential structure of light steel structure is composed of cold-formed thin-walled steel member system, and the steel frame is made of super anti-corrosion high strength cold-rolled galvanized sheet, which can effectively avoid the influence of steel corrosion in the process of construction and use, and increase the service life of light steel members. The life of the structure can reach 100 years.
Comfort
The light steel wall adopts high efficiency and energy-saving system, which has breathing function and can adjust the indoor air dry humidity; the roof has ventilation function, which can form a flowing air room above the house to ensure the ventilation and heat dissipation demand inside the roof.
