Fire Resistant Modern Commercial Steel Structures Heavy For Shopping Mall

Product Description:

The load bearing parts are mainly steel structures, including steel columns, steel beams
steel structural basements, bracing systems for wall and roof. The Main Structure are usually made of Q345 Steel while the Purlins and Bracing System are made of Q235 Steel. They are the most common steel materials used for steel structure in China.

Steel Structure Performance:

1) Seismic resistance

Low-rise villa roof are mostly sloping roof, roof structure is basically used by the cold-formed steel members made of triangular roof truss system, light steel structure in the finished structural sheet and gypsum board, the formation of a very strong " Plate rib structure system ", this structural system has a stronger seismic resistance and horizontal load capacity, suitable for seismic intensity of 8 degrees above the region.

2) Wind resistance

Steel structure of light weight, high strength, the overall rigidity, deformation ability. Building weight is only one-fifth of brick and concrete structure, can withstand 70 meters per second hurricane, so that life and property can be effectively protected.

3) Durability

The steel structure is made of super anti corrosive and high strength cold-rolled galvanized sheet, which effectively avoids the influence of rust in the course of construction and use, and increases the service life of the light steel structure. Structure life of up to 100 years.

4) insulation

The use of thermal insulation materials to glass fiber cotton-based, with good insulation effect. With the external wall insulation board, effective to avoid the wall of the "cold bridge" phenomenon, to achieve a better insulation effect. 100mm thick R15 thermal insulation cotton thermal resistance can be equivalent to 1m thick brick wall.

5) sound insulation

Sound insulation effect is an important indicator of the assessment of residential, light steel system are installed using insulating glass windows, sound insulation, sound insulation of 40 dB or more; by the light steel keel, gypsum board insulation material composition of the wall, the noise effect can be as high as 60 dB.

6) health

Dry construction, to reduce environmental pollution caused by waste, housing steel structure materials can be 100% recovery, other supporting materials can also be the majority of recycling, in line with current environmental awareness; all materials for the green building materials to meet the ecological environment, is conducive to health .

7) comfort

Light wall with energy efficient system, with breathing function, can adjust the indoor air humidity; roof with ventilation, can make the house over the formation of the flow of air between the roof to ensure that the internal ventilation and cooling requirements.

8) fast installation

All dry construction, environmental impact from the season. A building of about 300 square meters, only 5 workers 30 working days to complete the whole process from the foundation to the decoration.

9) environmental protection

Materials can be 100% recycled, truly green pollution-free.

10) Energy saving

All use of energy efficient wall, insulation, insulation, sound effects, and can reach 50% of the energy-saving standards.
