The largest characteristic of aluminum and aluminum alloy is that its bulk density is about 1/3 of steel, while the ratio of strength (strength limit to proportion) can reach or exceed structural steel.Secondly, aluminum and aluminum alloy are easy to be processed into various shapes and can adapt to various connection processes, thus providing favorable conditions for the construction structure to adopt the most economical and reasonable section form.Therefore, the use of aluminum alloy can not only greatly reduce the weight of buildings, save materials, but also reduce the transportation and installation of components and speed up construction progress.The economic effect is more significant in the mountainous areas and remote areas where the earthquake zone and transportation are inconvenient.Aluminum and aluminum alloy are beautiful in color, good corrosion resistance, high reflectivity of light and heat, good sound absorption, and various colors can be obtained through chemical and electrochemical methods.So aluminum is widely used in industrial and civil architecture roofing, inside and outside walls, doors and Windows, skeleton, decorative board, ceiling, ceiling, handrail, indoor furniture, shops and construction with the template.
Construction industry is one of the three major market aluminum, about 20% of the total aluminium production in the world for use in construction, the construction of some industrial developed countries, the amount of aluminum have accounted for more than 30% of its total production.In recent years, the products of building aluminum products are continuously updated, and the application of new architectural products such as color aluminum plate, composite aluminum plate, composite door window frame and aluminum alloy template is also increasing year by year.China has used aluminum alloy in industrial and civil building to make roofing, metope, door and window, etc., and gradually expand the interior and exterior decoration, construction use template and so on, has achieved good effect.
