Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods.

Aluminum profiles can be divided into: 1. Architectural aluminum profiles for doors and windows; 2. Special aluminum profiles for CPU heat sinks; 3. Aluminum alloy shelves are aluminum shaped.

According to alloy composition, it can be divided into: 1. Anodized aluminum material; 2. Electrophoretic coating of aluminum materials; 3. Powder coated aluminum material; 4. Wood grain transfer printing of aluminum material; 5. Planed aluminum material.

Taking industrial aluminum profiles as an example, please elaborate on the specifications of aluminum profiles. In addition to large-sized profiles, the specifications of industrial aluminum profiles are mostly small and medium-sized profiles. Aluminum profile manufacturers have a large proportion in industrial profiles, with a wide variety of specifications and small batches being the characteristics of aluminum profiles. Moreover, some industries have not yet developed materials, which may have more potential than large profiles. The production process of aluminum profiles should appropriately consider slowing down the construction of large and extra large extrusion production lines. There are more than ten large and super large aluminum extrusion production lines that have been built or are under construction in China, with a production capacity of over 100kt/a, greatly exceeding the demand for large-scale extrusion materials in the near future. In recent years, most of the large and super large extrusion production lines have been built with the goal of rail vehicle profiles. However, the demand for rail vehicle profiles is very limited. After several extrusion production lines are completed, due to the significant difference between demand and production capacity, if we cannot increase the development efforts of large material demand in other industries, it will inevitably cause fierce competition in the rail vehicle profile production line, Going back to large-scale extrusion production lines now may put enterprises in a very passive position. Increase the development of industrial aluminum profiles. The demand for industrial aluminum profiles is not only limited by the overall industrial level, but also related to insufficient development efforts.
