Classification of metal and metal composite materials for building decoration
Structural materials
1. Steel structure
Steel structures have been widely promoted and applied all over the country due to their comprehensive advantages such as high strength, light weight, good seismic performance, high degree of industrialization, short construction period, strong plasticity, energy saving and environmental protection, and many large-scale and complex structures have been built. Steel structure workshops, long-span steel structure civil buildings and railway bridges, etc.
2. Color steel sandwich panel
The color steel sandwich panel not only has the characteristics of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials. With the advancement of science and technology, the improvement of people's living standards and the continuous enhancement of environmental protection awareness, color steel sandwich panel prefab houses are increasingly showing their strong vitality and broad market prospects. Favored by transportation, interior decoration, office appliances and other related industries. At present, the cores used in this product mainly include phenolic foam, polyphenylene, extruded polystyrene, rigid polyurethane, tripolyester and rock wool, etc. The phenolic foam has excellent fireproof and thermal insulation properties and cannot be replaced by other materials. With the emphasis on building fire safety and the introduction of relevant laws, it is believed that phenolic color steel sandwich panels will create a blue sky in the field of construction.
Metal veneer and ceiling
1. Metal veneer
At present, the metal curtain wall accounts for 1/3 of the curtain wall project, about 30 million m2. Metal veneer is mainly made of aluminum veneer. Aluminum veneer is one of the building decoration materials that has developed rapidly in recent years. It is mainly used in the interior and exterior decoration of building exterior walls, ceilings and public buildings. From the perspective of the development of the domestic industry itself, although the overall level of technical equipment in the aluminum veneer industry is relatively high, the overall level of enterprises is still mixed, among which enterprises are small in scale, simple in equipment, extensive in management, and poor in standard quality awareness. ratio, and even individual enterprises are still in the production stage of family workshops, and it is difficult to guarantee the quality, not to mention the scale effect. In addition, the market is not standardized, disorderly competition, and some unscrupulous manufacturers are shoddy, which has greatly disrupted the market order. The aluminum veneer made of inferior aluminum plate (replacing the special aluminum plate for curtain wall with ordinary aluminum plate) or coating (replacing the fluorocarbon coating with excellent durability with polyester coating) has its own strength and weather resistance greatly reduced, which is a serious threat to the building. quality of engineering. For the entire industry, it has greatly damaged the credibility of the aluminum veneer itself.
2. Metal ceiling panels
Metal ceiling panels are mainly made of aluminum ceilings, accounting for about 73% of the entire ceiling market, mainly concentrated in Zhejiang, Guangdong, Shandong, Shanghai, Beijing, Jiangsu and other provinces and cities, especially Jiaxing, Zhejiang has become a domestic integrated ceiling production Base, the industry is developing very rapidly.
composite material
Metal composite decorative materials have the characteristics of low cost and high performance, and are in line with the relevant policies of energy conservation and energy conservation of building materials, so they have a broad space for development.
1. Aluminum-plastic composite panel
Aluminum-plastic composite panels have rich and colorful decorative effects and good durability. They are recyclable green products and are widely used in building curtain walls, indoor and outdoor decoration, advertising boards, etc.
2. Aluminum honeycomb panel and corrugated composite panel
Aluminum honeycomb panels and corrugated composite panels have excellent properties such as high flatness, high wind pressure resistance, shock absorption, sound insulation, heat preservation, and flame retardancy. They can be combined with metals and stone materials, and are widely used in building curtain walls, interior walls, partitions, and ceilings , planes, trains and furniture.
Aluminum profiles for aluminum alloy doors, windows and curtain walls
With the pace of reform and opening up, aluminum alloy profiles have quietly emerged, and a huge industry has gradually formed around aluminum alloy doors and windows and building curtain walls. Under the promotion of building energy-saving policies, high-performance profile products such as heat-insulating aluminum alloy profiles and aluminum-wood composite profiles will have a broader space for development.
