The steel structure exterior wall materials must have basic properties such as corrosion resistance, high temperature resistance, aging resistance, no radiation, fire prevention, insect prevention, no deformation, etc. at the same time, it also requires beautiful appearance, simple construction, environmental protection and energy conservation.
Steel structure exterior wall material 1 - fiber cement exterior wall cladding
The fiber cement exterior wall panel is fireproof and anti-corrosion, and the deadweight of the material is relatively large. Generally, keel is required for installation, and the surface needs to be painted. The appearance effect depends on the service life of the coating.
Steel structure exterior wall material 2 - metal exterior wall cladding
The metal external wall hanging plate is a composite material, which is mainly composed of three parts. The surface is a decorative metal plate, the middle layer is a polyurethane foam insulation layer, and the bottom is an aluminum foil protective layer. The cost of metal external wall cladding is relatively high, and the installation requirements are relatively complex.
Steel structure exterior wall material 3 - PVC exterior wall hanging plate
PVC external wall hanging plate, which is a plastic profile with rigid PVC as the main body, is used for the external wall of buildings; It can cover, protect and decorate. PVC exterior wall cladding can also be recycled. The energy consumption in the manufacturing process is lower than that of cement and ceramic tiles. It is a green building material conducive to environmental protection.
The installation and construction of PVC external wall hanging plate is simple and fast, which can be combined with walls of various structures; The construction of all dry operations is basically not affected by seasons; It is easy to clean during use (it can be washed with water); No maintenance (no paint and coating); The performance price ratio is high. The external wall cladding also has the advantages of flame retardancy, moisture resistance, corrosion resistance, aging resistance, etc. The service life can reach more than 30 years. Richness, traditional colors and fine texture will make the house beautiful and new.
The color of the hanging plate comes from the product body, and the phenomenon of embrittlement, peeling and blistering of the ordinary paint surface will never occur. It is also different from wood. It rots or bends and deforms due to moisture. More importantly, PVC exterior wall cladding uses a solid ethylene material layer to protect the house. The solid polyethylene material structure design can withstand the attack of bad weather, making the house as new for many years.
Steel structure exterior wall material 4 - stone exterior wall cladding
Stone is also a common wall cladding, which has most of the functions required by wall cladding and is also used by many buildings. The defects of stone materials are: first, some stone materials have radiation, which will cause certain harm to the human body; Second, stone is a non renewable resource with high price; Third, because of its heavy weight, it has high requirements on the exterior wall and steel structure.
