In order to save costs, many customers generally choose cheaper industrial aluminum profiles. It is easy for these insulated bridge aluminum profiles to be oxidized and deformed before long. In fact, the material of industrial aluminum profiles is not so-called good or bad, but the chemical composition ratio of industrial aluminum profiles depends on the scope of later use. So how can consumers distinguish between good and bad industrial aluminum profiles?

1. Observe the degree of oxidation:
When purchasing, you can swipe the surface of the industrial aluminum profiles displayed by the merchant to see if the oxide film on the surface can be wiped off.

Second, observe the chromaticity:
The same industrial aluminum profiles should have the same color and uniform texture. The cross-section color is silvery white. If the color difference is obvious, it is not suitable for purchase. If the color is black, it can be concluded that it is recycled aluminum or scrap aluminum forging.

Three, observe the flatness:
Visually inspect the surface of the industrial aluminum profiles, and they should be smooth and flat without dents or bulges. The surface of the industrial aluminum profiles processed by the regular insulated bridge aluminum profiles manufacturer is smooth and bright. If it is a small workshop because of the machine or raw materials, the surface of the industrial aluminum profiles will appear slightly uneven. This kind of industrial aluminum profiles are easily oxidized and deformed in the later stage. .

Four, observation intensity:
When purchasing, you can bend the profile moderately with your hands. If you bend the profile without force, it can be determined that the strength of the industrial aluminum profiles is not up to the standard. In addition, the strength of the profile is not as hard as possible. Aluminum itself has a certain degree of toughness and is not a hard material. It is easy to forge different shapes by using this feature, so consumers need to observe carefully when purchasing.

Five, observe the gloss:
Consumers who purchase industrial aluminum profiles for doors and windows should avoid profiles with obvious defects such as open bubbles and slag on the surface, as well as cracks, burrs and peeling. If there are the above phenomena, it can basically be concluded that secondary processing and forming of recycled aluminum or scrap aluminum. Such materials are prone to cracking and oxidation in the later stage due to uneven texture and disordered alloy ratio.
