Steel structure workshop performance

Shock resistance
The roofs of low-rise villas are mostly sloping roofs, so the roof structure basically uses a triangular roof truss system made of cold-formed steel components. The light steel components form a very strong structure after sealing the structural plates and gypsum boards. "Slab-rib structure system", this kind of structure system has stronger seismic resistance and resistance to horizontal loads, and is suitable for areas with seismic intensity above 8 degrees.
 
Wind resistance
The profiled steel structure building has light weight, high strength, good overall rigidity and strong deformability. The weight of the building is only one-fifth of the brick-concrete structure, and it can withstand a hurricane of 70 meters per second, so that life and property can be effectively protected.
Durability
The residential structure of light steel structure is all composed of cold-formed 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 steel plate corrosion during construction and use, and increases the service life of light steel components. The structural life can reach 100 years.
Heat preservation
The thermal insulation material used is mainly glass fiber cotton, which has good thermal insulation effect. The use of thermal insulation boards on the outer wall effectively avoids the "cold bridge" phenomenon of the wall and achieves a better thermal insulation effect. The thermal resistance of R15 insulation wool with a thickness of about 100mm can be equivalent to that of a brick wall with a thickness of 1m.
Sound insulation
The sound insulation effect is an important indicator for evaluating the residence. The windows installed in the light steel system are made of hollow glass, which has good sound insulation effect, and the sound insulation can reach more than 40 decibels; the wall composed of light steel keel and thermal insulation material gypsum board has a sound insulation effect of up to 60 decibels.
Health
Dry construction reduces the environmental pollution caused by waste. The steel structure of the house can be 100% recycled, and most of the other supporting materials can also be recycled, which is in line with current environmental protection awareness; all materials are green building materials that meet the requirements of the ecological environment and are beneficial to health . ?
Comfort
The light steel wall adopts a high-efficiency energy-saving system with breathing function, which can adjust the dry humidity of the indoor air; the roof has a ventilation function, which can form a flowing air space above the house to ensure the ventilation and heat dissipation requirements inside the roof.
Fast
All dry work construction, not affected by the environmental season. For a building of about 300 square meters, only 5 workers and 30 working days can complete the whole process from foundation to decoration.
Environmental protection
The material can be recycled 100%, truly green and pollution-free.
Energy saving
All use high-efficiency energy-saving walls, with good heat preservation, heat insulation and sound insulation effects, and can reach the energy-saving standard of 50%.
