The roof of low rise villas are sloping roof, the roof structure basically adopts the triangular truss system made of cold-formed steel, light steel members in sealed end structural plate and plaster board, formed a very strong "plate structure", this kind of structure system with capability of earthquake resistance and load stronger, suitable for seismic intensity of 8 degrees in the area.
The steel structure is light in weight, high in strength, good in overall rigidity and strong in deformation. The weight of the building is only 1/5 of the brick concrete structure. It can withstand the hurricane of 70 meters per second, so that the life and property can be effectively protected.
Light steel structure residential cold-formed thin-walled steel structure using all system components, steel using super anticorrosion high strength cold rolled galvanized sheet manufacturing, effectively avoid the influence of the steel in the construction and use of the process of corrosion, increase the service life of steel member. Structure life up to 100 years.
The heat insulation material adopted is mainly made of polyurethane sandwich board, and has good heat insulation effect. The utility model relates to an outer wall heat insulation board, which effectively avoids the phenomenon of cold bridge of a wall, and achieves better heat preservation effect. 50mm or so thick polyurethane sandwich board thermal resistance value may be equivalent to 1m-thickness brick wall.
The sound effect is an important index for assessment of residential, light steel system installation window adopts hollow glass, sound insulation, sound more than 40 db; the polyurethane sandwich panel insulation material of the wall, the sound insulation effect can be as high as 80 db.
Dry construction, reduce pollution to the environment, the steel structure housing the material can be recycled 100%, other supporting materials may also be most recovery, with the current environmental protection consciousness; all materials for green building materials, meet the requirement of the ecological environment, conducive to health.
The use of energy-efficient light steel wall system, with respiratory function, can regulate indoor air humidity; roof with ventilation function, can make the house form over the air flow, to ensure the roof inside of the ventilation and cooling demand.
All dry work is not affected by environmental season. A building of about 300 square meters, only 5 workers, 20 working days can be completed from the ground to the entire process of decoration.
Material can be recycled 100%, and truly green pollution-free.
All use energy-efficient (polyurethane sandwich board) wall, insulation, heat insulation, sound insulation effect is good, can reach 60% of the energy efficiency standards.INSTALLATIONOUR PROJECTSINSTALLATION GUIDE
Usually steel structure building is a large installation engineering. Some customers may need SBS assign the professional technical engineer to supervise the installation on site overseas. To such situation, customer should coordinate with us for following aspects:CUSTOMERS VISITCustomer should provide:
1. Translator or assistant on site.
2. All costs raised including:
A. visa fee
B. Round trip flight ticket
C. Accident insurance for the supervisor during the period
E. Daily meals
G. Local traffic fee (if any)
3. The customer should pay the engineer with supervision fee, which can be negotiated and decided by both.
4. Customer has the responsibility to provide necessary security system to protect the supervisor, especially in some unrest countries.Welcome to contact us:
