In order to meet the purpose of environmental protection, energy saving, and beautiful appearance of modern buildings, the selection and design of exterior wall materials are becoming more and more diverse and important. The quality of exterior wall design not only affects the overall shape, but also affects the difficulty of the construction process and the maintenance after completion.
1. Aluminum exterior wall
Aluminum exterior wall accounts for the largest number of metals used. It is cheaper than other metals, lighter, easier to install and transport, and has many superior properties:
Through surface chemical treatment methods, the color changes greatly and the finished product is bright and shiny.
Aluminum is a corrosion-resistant metal, and through special treatment it can have good durability and weather resistance.
After fluorocarbon paint surface treatment, the color is beautiful, and the cleaning method is simple, and it can be handled with general neutral detergent.
Lightweight, excellent seismic resistance, and can be elastically displaced with the structure.
2. Enameled steel plate exterior wall
Enameled steel plate is also a material used in more and more buildings. Generally, the surface of the enamel steel plate is coated with glass glaze and melted at a high temperature of 850°C. It is a kind of building panel with the characteristics of metal and the hardness and beauty of glass. It is a high-quality building material with the following characteristics:
There are many color combinations, and the color stability is excellent, and it is not easy to change or fade.
It has excellent weather resistance to temperature, humidity, etc., and is not affected by acids, alkalis, and salts. It is also very resistant to grease, chemicals, etc.; it is not easy to burn, and can be used as an excellent refractory material after special treatment.
The appearance of enamel material gives people a lighter feeling than the appearance of metals such as stainless steel. Because of its smooth surface and high hardness, it is not easy to wear and stain, so it can always be kept clean and beautiful.
It can reduce the weight of the building itself and reduce construction costs. In addition, it can also shorten the construction period and reduce the thickness of the wall, making the overall appearance design more free and flexible.
3. Stainless steel exterior wall
Stainless steel exterior wall is a common exterior wall material in modern times. It can show the innovative sense of building appearance, and the material has various changes. It is a beautiful and practical choice:
Stainless steel plate surface can be processed in various ways (such as sandblasting, pickling or mirror treatment), which can show extremely beautiful luster and gorgeousness, and the color changes are also various.
Stainless steel has good weather resistance, is not easy to be polluted and corroded, and has excellent wear resistance and a long service life.
It can be cleaned with weak acid solution. The material is thicker than aluminum. Due to its high hardness and density, it is less likely to get dirty than aluminum and can maintain its original appearance for a long time.
4. Glass exterior wall
Glass exterior walls are commonly seen in public space buildings such as office buildings and airports. They are often processed in combination with metal parts. They can show high transparency and light transmittance, achieve beautiful and energy-saving effects, and can show a variety of building appearances at different angles and in different lights. It is a major feature of modern architectural aesthetics.
5. Stone exterior wall
The selection of stone for exterior wall building materials can express natural images and has the characteristics of being strong and durable. Most common stones have the advantages of high hardness and good weather resistance. They are also cheaper and easier to maintain than other materials. However, it is necessary to pay attention to the influence of thermal expansion and contraction of the weather, which may cause damage and cracks. Recently, with the improvement of construction technology, this problem has been greatly improved.
In summary, the exterior wall of the building is the outermost layer of the facade and building. In addition to beauty, the selection of materials also needs to consider safety, maintenance cost, durability and overall construction engineering factors. In addition, the climate and conditions of the environment should also be taken into consideration.
