Most of the roofs of low-rise villas are sloping roofs, so the roof structure basically adopts a triangular roof truss system made of cold-bent steel components. After the light steel components are sealed with structural plates and gypsum boards, a very strong "plate rib structure system" is formed. This structural system has stronger earthquake resistance and horizontal load resistance, and is suitable for areas with an earthquake intensity of 8 degrees or above.
2. Wind resistance
Steel structure buildings are light in weight, high in strength, good in overall rigidity, and strong in deformation capacity. The building's deadweight is only one-fifth of that of a brick-concrete structure, and it can withstand a hurricane of 70 meters per second, so that life and property can be effectively protected.
3. Durability
The light steel structure residential structure is entirely composed of a cold-bent thin-walled steel component system, and the steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of rust on the steel plate during construction and use, and increases the service life of the light steel components. The structural life can reach 100 years.
4. Thermal insulation
The thermal insulation material used is mainly glass fiber wool, which has good thermal insulation effect. The thermal insulation board used for the exterior wall effectively avoids the "cold bridge" phenomenon of the wall and achieves better thermal insulation effect. The thermal resistance value of R15 thermal insulation wool with a thickness of about 100mm is equivalent to that of a 1m thick brick wall.
5. Sound insulation
Sound insulation effect is an important indicator for evaluating residential buildings. The windows installed in the light steel system all use hollow glass, which has good sound insulation effect and can reach more than 40 decibels; the wall composed of light steel keel and thermal insulation material gypsum board can have a sound insulation effect of up to 60 decibels.
6. Health
Operation construction reduces the pollution caused by waste to the environment. The steel structure materials of the house can be 100% recycled, and most of other supporting materials can also be recycled, which is in line with the current environmental awareness; all materials are green building materials, meet the requirements of the ecological environment, and are beneficial to health.
7. Comfortability
The light steel wall adopts an efficient energy-saving system, has a breathing function, and can adjust the indoor air humidity; the roof has a ventilation function, which can form a flowing air space above the house to ensure the ventilation and heat dissipation needs inside the roof.
8. Fast
All dry construction is not affected by the environment and season. For a building of about 300 square meters, only 5 workers need 30 working days to complete the whole process from foundation to decoration.
9. Environmental protection
The materials can be 100% recycled, which is truly green and pollution-free.
10. Energy saving
All adopt efficient energy-saving walls, with good insulation, heat insulation and sound insulation effects, which can reach 50% energy saving standards.
