The construction industry is one of the main markets for aluminum profiles. About 20% of the total aluminum output is used in the construction industry. In some industrially developed construction industries, the amount of aluminum used has accounted for more than 30% of its total output. In recent years, the products of architectural aluminum have been continuously updated, and the application of new architectural products such as colored aluminum, composite aluminum panels, composite door and window frames, and aluminum alloy templates has also increased year by year.

One of the main advantages of aluminum alloy structure is corrosion resistance and durability. Aluminum alloy structure green buildings are widely used in environments with high humidity, acid rain, harsh climate changes or coastal areas. In building structures, especially in modern high-rise civil buildings and large public buildings with large spans and thin shell structures, aluminum alloy structures have obvious advantages compared with steel structures:

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.). Precise hollow, solid, constant section, variable section profiles, pipes, bars, plates, forgings, die forgings and punching and bending parts, etc., and can make the section form of the components more reasonable.

Aluminum profiles are used in roofs, walls, doors and windows, skeletons, reticulated shell structures, grid structures, glass curtain wall support systems, canopies, communication towers, pedestrian bridges, interior and exterior decorative panels, partitions, ceilings, suspended ceilings, and railings in industrial and civil buildings. Handrails, interior furniture, decorative materials and structural components, store containers and formwork for construction are widely used and have achieved good results.

As a semi-structured structure, the durability of architectural aluminum profile is very important. We know that aluminum alloy building profiles are divided into substrates, anodized profiles, electrophoretic paint profiles, powder spray profiles, fluorocarbon paint spray profiles, strip insulation profiles, glue injection insulation profiles, etc. Users in coastal areas should choose electrophoretic painted aluminum profiles, powder sprayed aluminum profiles or fluorocarbon sprayed aluminum profiles with better corrosion resistance.
