Dingfeng Aluminum coils products made of aluminum and aluminum alloys.Prepainted 3105 H46 aluminum coils are PE/PVDF/FEVE/HDPE coating

For construction

Usually, it is first processed into casting products, forging products and foils, plates, belts, pipes, rods, profiles, etc., and then made by cold bending, sawing, drilling, assembly, coloring and other processes. Performance Pure aluminum has low strength and its use is limited. But add a small amount of one or more alloying elements, such as magnesium, silicon, manganese，Copper, zinc, iron, Ming, titanium, etc., can be obtained with different properties of aluminum alloy. After cold working and heat treatment, aluminum alloy is further strengthened and hardened, and its tensile strength is greatly improved. The biggest characteristic of aluminum and aluminum alloys is that their bulk density is about 1/3 that of steel, and their specific strength (the ratio of strength limit to specific gravity) can reach or exceed that of structural steel.

Secondly, aluminum and aluminum alloy are easy to process into a variety of shapes, can adapt to a variety of connection technology, so as to provide favorable conditions for the construction of the most economical and reasonable section form. Therefore, the use of aluminum alloy can not only greatly reduce the weight of the building, save materials, but also reduce the transportation of components, installation workload, speed up the construction progress. This for the earthquake area and transportation inconvenient mountainous and remote areas, its economic effect is more significant. Aluminum and aluminum alloy color beautiful, good corrosion resistance, high reflectance to light and heat, good sound absorption performance, through chemical and electrochemical methods can obtain a variety of different colors. Therefore, aluminum is widely used in roofing, walls, doors and Windows, skeletons, interior and exterior decorative panels, ceilings, suspended ceilings, railings, interior furniture, store containers and construction templates, etc.

The construction industry is one of the three major markets for aluminum. About 20% of the world's total aluminum production is used in the construction industry. The construction industry in some industrially developed countries already uses more than 30% of its total aluminum production. In recent years, the products of architectural aluminum are constantly updated, and the application of novel architectural products such as colored aluminum plate, composite aluminum plate, composite door and window frame, aluminum alloy template is also increasing year by year. In China, aluminum alloy has been applied in industrial and civil buildings to make roofing, walls, doors and Windows, and has gradually expanded to interior and exterior decoration, construction formwork, etc., and has achieved good results.
