Most roof of the low rise villas are sloping roof, so the roof structure basically are made of cold-formed steel by adopting the triangular truss system, light steel members in sealed end structural plate and plaster board, formed a very strong "plate structure", this kind of structure system with the stronger resistance of earthquake and the capacity of horizontal loads, suitable for the area seismic intensity above 8 degrees.
The prefab steel structure is light in weight, high in strength, good in overall rigidity and strong in deformation resistance. The weight of the building is only 1/5 of the brick concrete structure, which can resist the hurricane of 70 meters per second, so that the life and property can be effectively protected.
the structure of lightweight steel construction housing is made up of cold bend thin-wall steel component system, reinforcing bar is made of super corrosion resistant high-strength cold-rolled galvanized sheet, which effectively avoids the influence of steel plate corrosion in construction and use procedure, and increases the service life of light steel component. The structural life-time can be up to 100 years.
The material of keeping warm is mainly made of gfiberlass cotton, and the heat insulation effect is good. The insulation board of periphery wall could avoid the "cold bridge" phenomenon of the wall effectively , and achieve better insulation effect. The thermal resistance of R15 heat insulation cotton with 100mm thickness is equivalent to that the thick of brick wall about 1m.
The effect of insulation is an important index for assessment of residential, the installation of window of light steel system adopts insulating glass, so the effict of sound insulation is good, which could resist sound more than 40 db; Composed of lightgage steel joist, plasterboard made by heat insulating material, the sound insulation effect can reach as high as 60 db.
Dry construction, the pollution to the environment is reduced , the material of steel structure housing the can be recycled 100%,most other assorted materials could also be recovered, it’s conforming to the current environmental protection consciousness; all materials of us are green building materials, fulfiling the requirement of the ecological environment, and advantages to health.
Light steel wall adopts energy-efficient system, has breathing function, can adjust the room air dry humidity; the roof with function of ventilationing, can make thr overhead of the house form the flowing air room, to ensure the roof of the ventilation and heat dissipation demand.
Dry construction all the time,won’t be affected by the environmental of season.To complete the whole process from the foundation to the decoration of a building with 300 square meters jsut need only 5 workers and 30 working days.
Materials can be recycled 100%, truly green pollution-free.
all are energy-efficient walls, insulation, th effect of heat insulation,and sound insulation is good, can reach 50% of the energy saving standards.
