(1) Aluminum alloy is currently the most ideal green building structural material in the world, industrialized and widely used, promoting the development of green building industry, promoting the process of urbanization and industrialization in China, and promoting the rapid development of the national economy and society. The progress of civilization is of great significance. At the same time, it will promote the development of aluminum alloy processing industry and technology. (2) The use of aluminum instead of wood in the building structure makes the aluminum alloy a true “green building†material, because the substitution of aluminum can greatly reduce the protection of forests and protect the earth's green and low carbon. In addition, compared with wood structure, aluminum structure has high strength and rigidity, good water tightness, air tightness, good corrosion resistance, low cost and high recoverability, which can reduce structural section, increase building area, save land and Energy, transportation, construction, maintenance and loading and unloading are convenient. Therefore, the aluminum alloy structural material is a true low carbon, green, and recyclable building material. (3) In the building structure, especially in modern high-rise civil buildings and large-scale public buildings with large span and thin shell structure, the aluminum alloy structure has obvious advantages compared with the steel structure: Low density The density of aluminum alloy is only 1/3 of the density of steel, and its strength is higher than that of steel. It is an ideal lightweight material. For high-rise and long-span and thin-shell structures, the weight of the aluminum alloy space structure is much lighter than that of the steel structure, so the basic investment of the structure is much less. high strength Generally, the b of medium-strength aluminum alloy material can reach more than 300MPa, which is equivalent to Q235 steel. The b of 7075T6 ultra-high-strength aluminum alloy can reach 700MPa, which is comparable to high-strength alloy steel, exceeding the high-strength steel Q345, and the density of aluminum alloy is small, aluminum The spatial structure of the alloy material is light in weight. Precision structural parts that can be fabricated into a variety of shapes and sizes Compared with steel, aluminum alloy has good plasticity and formability, and can be processed into various specifications and shapes in large quantities under cold and hot conditions by various pressure processing methods (extrusion, rolling, forging and stamping, etc.). Precision hollow, solid, constant-section, variable-section profiles, pipes, rods, plates, forgings, die forgings and punching parts, etc., and can make the cross-section of the components more reasonable. It can meet the requirements of any building structure without the need for precision machining conditions. This is not possible with hot rolling, cold rolling, extrusion or welding of steel. Easy on-site transportation and installation Due to the light weight of the aluminum alloy structure, there is no need for large heavy machinery on site, and the transportation installation is extremely light, so the on-site construction period can be greatly shortened and the cost is greatly reduced. Corrosion resistant, surface treatable, beautiful and durable Compared with the steel structure, one of the main advantages of the aluminum alloy structure is corrosion resistance and durability. The anti-corrosion workload in the building life is small, the protection and maintenance cost is low, and the normal production operation and use are not affected by the anti-corrosion maintenance. Aluminum structure Green buildings are widely used in environments with high humidity, acid rain, and severe climate change or coastal areas. Non-stick water, good water tightness, waterproof, and prevent leakage Since the aluminum alloy structure of the aluminum alloy building system is integrated with the aluminum alloy roofing material, the joint form can be perfectly combined with the roofing material to achieve zero leakage and waterproof, and the aluminum processed material is not sticky, and is not afraid of water leakage and corrosion. Recyclable recycling The recovery cost of aluminum alloy materials is very low, and the energy consumption is only 5% of that of electrolytic aluminum. The recycling rate can be reused again, and the recovery rate can reach more than 90% (more than 5 times of the steel recovery rate). The basic and aluminum ingot prices are not much different, and it is a typical green environmental protection material. Green processing The use of aluminum alloy structure enables full-fit construction to meet the standards of modular construction and industrialization of buildings. The construction site has no noise, no dust, no pollution to water and gas, and is a typical green material and green construction. Save land, energy and construction costs Under the same span, the structural section is greatly reduced (about 1/8 section of the steel structure), which can increase the use area of ​​about 6% of the building, reduce the waste of space by about 10%, and save land and energy. At the same time, the construction cost is greatly saved. It can be seen that replacing the steel structure with aluminum alloy structure can make the construction project and construction green and environmentally friendly, which can greatly save resources, energy and construction and maintenance and use costs, and has significant economic benefits and obvious social benefits. Accelerate the process of urbanization and industrialization in China, ensure the rapid and sustained development of the national economy and improve the quality of China's economic growth and social and civilized development. At the same time, it can expand the use of aluminum and market share, and promote the development of aluminum processing (especially extrusion processing) and technological advancement.
H beam have many advantages, like better mechanical performance, large section modulus, low weight and saving metal. That can make architectural structure reduce 30-40% weight; save welding and riveting work up to 25%. H beam is often used in mega-structures(such as plant, high-rise building etc. ) which require great bearing capacity and better stable section, also used in bridge, ship, hoisting and conveying machinery, equipment foundations and support.
