What is the difference among industrial aluminum profiles and architectural aluminum profiles?

Update time : 2022-09-26 10:54:54

Industrial aluminum profiles and architectural aluminum profiles, so their alloy composition and alloy content are the same, so there is no difference in mechanical properties between industrial aluminum profiles and architectural aluminum profiles. In addition, they have no difference in weldability, electrical and thermal conductivity, surface treatment, corrosion resistance and cutting performance. So, what is the difference between industrial aluminum profiles and architectural aluminum profiles?

1. Different cross-sectional shapes

Industrial aluminum profiles are mostly symmetrical structures. Most of the architectural aluminum profiles are asymmetrical in section, have a relatively large degree of bending, and some cantilevers are relatively large. However, industrial aluminum profiles have more cavities than architectural aluminum profiles, and most of them are circle holes.

2. Different wall thickness

Generally speaking, the wall thickness of industrial aluminum profiles is larger than that of architectural aluminum profiles. Because the load-bearing capacity of the door, window and curtain wall profiles is not so high and the decoration is relatively strong, the wall thickness is relatively thin. Industrial aluminum profiles are mostly used on equipment frames and brackets, so the load-bearing requirements are higher and the wall thickness is thicker.

3. Different surface treatment methods

Generally, the surface of industrial aluminum profiles only needs anodizing treatment, and at most one sandblasting process is added to make a matte effect. However, there are many methods for surface treatment of architectural aluminum profiles, such as spraying, electrophoresis, and wood grain transfer printing. Because architectural aluminum profiles pay more attention to decoration, the colors are richer. And industrial aluminum profiles pay attention to atmosphere and cleanliness, generally only need natural color oxidation treatment, a few need black oxidation.

4. Different quality requirements

Industrial aluminum profiles have higher tolerance requirements than architectural aluminum profiles, and the surface quality of the substrate is higher. Because of the transparent oxide film formed by anodization of industrial aluminum profiles, if there are any defects on the surface of the substrate, it is clear at a glance.
