Aluminum profiles can be categorized by application as follows: 1. Architectural aluminum profiles for doors and windows; 2. Specialized aluminum profiles for CPU heat sinks; 3. Aluminum profiles for aluminum alloy shelving.
According to alloy composition, aluminum materials can be categorized as follows: 1. Anodized aluminum; 2. Electrophoretic-coated aluminum; 3. Powder-coated aluminum; 4. Wood-grain transfer-printed aluminum; 5. Planed aluminum.
Taking industrial aluminum profiles as an example, let’s examine their specifications in detail: Besides large-sized profiles, the majority of industrial aluminum profiles are medium- and small-sized, accounting for a significant share of the industrial profile market. These profiles are characterized by a wide variety of types and specifications, coupled with relatively small batch sizes. Moreover, certain industries have yet to fully develop their demand for these materials, which suggests that medium- and small-sized profiles may hold even greater potential than large-sized ones. Therefore, it would be prudent to slow down the construction of large- and extra-large extrusion production lines. Currently, China has more than ten large- and extra-large aluminum extrusion production lines either completed or under construction, with a combined production capacity exceeding 100,000 tons per year—far surpassing the near-term demand for large-sized extruded products. In recent years, most of the newly commissioned large- and extra-large extrusion lines have been designed primarily for rail vehicle profiles. However, the demand for rail vehicle profiles is quite limited. Once several such extrusion lines are fully operational, the gap between demand and production capacity will become substantial. Unless efforts are stepped up to expand demand for large-sized profiles in other industries, fierce competition is inevitable on the rail vehicle profile production lines. Launching new large-scale extrusion lines at this stage could put enterprises in a highly vulnerable position. It is crucial to intensify the development of industrial aluminum profiles. On the one hand, the demand for industrial aluminum profiles is constrained by the overall level of industrial development; on the other hand, insufficient development efforts also play a role.
