Color-coated steel refers to color-coated steel plate. Color-coated steel plate is a steel plate with organic coating. It has good corrosion resistance, bright colors, beautiful appearance, convenient processing and forming, and has the original strength of steel plates.
Color-coated steel plates are widely used in construction appliances and transportation industries. For the construction industry, they are mainly used for roof walls and doors of industrial and commercial buildings such as steel structure factories, airports, warehouses and refrigeration. .
Advantages listed below:
1.Earthquake 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 color steel steel members. After the light steel members are sealed with structural plates and gypsum boards, they form a very The sturdy "slab structure system", this structure system has a stronger ability to resist earthquakes and horizontal loads, and is suitable for areas with an earthquake intensity of 8 degrees or more.
2.Wind resistance
Caigang steel structure building has light weight, high strength, good overall rigidity and strong deformation ability. The weight of the building is only one-fifth that of the brick-concrete structure, and it can resist hurricanes of 70 meters per second, so that life and property can be effectively protected.
3.Durability
The residential structure of the color steel structure is all composed of cold-formed thin-walled steel member systems. The steel skeleton is made of super anti-corrosion and high-strength cold-rolled galvanized sheet, which effectively avoids the influence of color steel during construction and use, and increases the service life of light steel components . Structure life is up to 100 years.
4.Insulation
The thermal insulation material used for the color steel sandwich panel is mainly glass fiber cotton, which has a good thermal insulation effect. The outer wall insulation board can effectively avoid the "cold bridge" phenomenon of the wall and achieve better insulation effect. The thermal resistance of R15 insulation cotton with a thickness of about 100mm can be equivalent to a 1m thick brick wall.
5.Sound insulation
The sound insulation effect is an important indicator for evaluating residential buildings. The windows installed in the color steel + light steel system all use hollow glass, which has a good sound insulation effect. The sound insulation is more than 40 decibels. The wall composed of light steel keel and insulation material gypsum board is soundproof. The effect can be as high as 60 dB.
6.Health
Dry work construction reduces the environmental pollution caused by waste. Color steel materials can be recycled 100%, and other supporting materials can also be mostly recycled, in line with current environmental awareness. All materials are green building materials, which meet the requirements of the ecological environment and are good for health.
7.Comfort
The color steel wall adopts a high-efficiency energy-saving system, which has a breathing function and can adjust the humidity of the indoor air. The roof has a ventilation function that can form a flowing air space above the house to ensure the ventilation and heat dissipation requirements inside the roof.
8.Fast
All dry work construction is not affected by the environmental season. For a building of about 300 square meters, only 5 workers and 30 working days can complete the entire process from foundation to renovation.
9.Environmental protection
Color steel materials can be 100% recycled, truly green and pollution-free.
10.Energy saving
All high-efficiency and energy-saving walls are used, which have good thermal insulation, heat insulation and sound insulation effects, and can reach the energy saving standard of 50%.
Color steel features:
1. Light weight: 10-14 kg / m2, equivalent to 1/30 of a brick wall
2. Thermal insulation: Thermal conductivity of core material: λ <= 0.041w / mk.
3. High strength: it can be used as the supporting structure of the ceiling, and it is resistant to bending and compression. Generally, beams and columns are not required for houses.
4. Bright color: No surface decoration is required, and the preservation period of the anticorrosive layer of the colored galvanized steel is 10-15 years.
5. Flexible and fast installation: the construction period can be shortened by more than 40%.
6. Oxygen index: (OI) 32.0 (Provincial Fire Products Inspection Station).
7. Oxygen index: (OI) 32.0 (Provincial Fire Products Quality Inspection Station).
