What material is used for the roof external wall of light steel structure building?

1, fiber cement external wall hanging plate

Fiber cement exterior wall panels are fireproof and anticorrosive, and the weight of materials is relatively large, so it is necessary to add keel and paint the surface during installation. The appearance depends on the age of the paint.

2, metal wall panels

Metal exterior wall hanging board is a kind of composite material, which mainly consists of three parts: the surface is decorative metal plate, the middle layer is polyurethane foam insulation layer, and the bottom surface is aluminum foil protection layer. The hanging board of metal external wall has high cost and complicated installation requirements.

3, stone wall hanging plate

Stone is also a common external wall hanging board, which has most of the functions required for external wall hanging board and is also adopted by many buildings. The defects of stone materials: first, some stone materials have radiation, which will cause certain harm to human body; Second, stone is a non-renewable resource and expensive; Third, it is heavy and requires high requirements for external walls and steel structures.

4.PVC external wall hanging board

PVC external wall hanging board is a plastic profile with hard PVC as the main body, which is used for the external wall of buildings; Play a role in covering, protecting and decorating. PVC external wall hanging board can also be recycled, and the energy consumption in the manufacturing process is lower than that of cement and tiles, so it is a green building material that is beneficial to environmental protection.

Advantages of light steel structure houses:

1, safe and reliable

The residence with steel as the main building material has high unit volume bearing capacity, which is more stable and firm than the traditional brick-wood and brick-concrete technology, and has better seismic performance, wind resistance, waterproof and fireproof performance, as well as heat insulation and sound insulation functions. Steel has good ductility and can better consume the energy brought by the earthquake, so it has good seismic performance and high structural safety, which ensures the safety of the house.

2. The building is simple and the construction period is short.

All components are prefabricated in the factory and assembled easily on site, which greatly shortens the construction period. A 6000-square-meter building can basically be installed in 40 days.

3, durable and easy to maintain

The steel structure building designed by general computer can resist bad weather and only needs simple maintenance.

4, beautiful and practical

The lines of steel structure buildings are concise and smooth, full of modern feeling. Color wallboard has many colors to choose from, and the wall can also be made of other materials, so it is more flexible.

5. Green and sustainable

All houses have a certain service life, and the raw materials demolished by ordinary brick-concrete houses can not be reused, which will produce a lot of garbage and pollute the environment. The steel of the steel structure residence can be recovered by 65,438+0,000%, and the environmental pollution during construction and demolition is small, which meets the requirements of residential industrialization and sustainable development.

Disadvantages of light steel structure houses:

1, the cost is relatively higher than the traditional brick-concrete and steel-concrete mixture.

2. With its unique steel skeleton, wall, roof and other materials, as well as standardized and stereotyped internal layout and supporting facilities, the steel structure residence is difficult to adapt to people's habit of "disposing of houses at will".

3. Corrosion of steel: aluminized and galvanized steel must be used to prevent corrosion to the greatest extent, and the main steel structure can last for 50 years.

There are many requirements for new materials. Thermal insulation materials will be used in steel residential buildings, and light new building materials will be widely used.
