How to distinguish the quality of industrial aluminum profile frame?
1. Whether there is an oxide film on the surface
Choosing a good aluminum profile is crucial. The brand processing factory not only selects high-quality raw materials in production and processing, but also anodizes the surface of aluminum profiles.
Therefore, the surface of high-quality frame aluminum profiles will have a very thick oxide film. What are the methods to identify the quality of aluminum profile frame?
2. Whether the surface is flat
The high-quality aluminum frame not only has a beautiful surface, but also the material is not skewed and deformed. In addition, the frame aluminum profile should have high flatness, which can ensure the use of different weights and is not easy to deform.
3. Consistent surface chromaticity
If the aluminum is recycled, scrap aluminum is added and the resulting aluminum frame will appear dark. The high-quality aluminum profile frame is generally made of high-quality aluminum ingot raw materials, so the aluminum produced not only has a uniform surface color, but also has a beautiful silver-white surface.
