Industrial aluminum profiles and architectural aluminum profiles belong to the 6063 grade 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. Other than that, their weldability, electrical and thermal conductivity, surface treatment, corrosion resistance and cutting performance are all the same, so what's the difference?

1. Different cross-sectional shapes

Industrial aluminum profiles are mostly symmetrical structures and relatively square. Most of the architectural aluminum profiles have asymmetric cross-sections, and the curvature is relatively large, and some have relatively large cantilevers. However, industrial aluminum profiles have more cavities than architectural aluminum profiles, and most of them are round holes.

2. Different wall thickness

In general, the wall thickness of industrial aluminum profiles is larger than that of architectural aluminum profiles. Because the load-bearing of the door, window and curtain wall profiles is not so high, it is more for decoration, so the wall thickness is relatively thin. Most industrial aluminum profiles are used on equipment frames and brackets, so they have higher load-bearing requirements and thicker wall thicknesses.

3. Different surface treatment methods

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

4. Different quality requirements

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