In the current construction of houses, the participation of industrial aluminum profiles is essential. Industrial aluminum profiles can be used for all aluminum profiles, except for aluminum doors and windows, curtain walls, indoor and outdoor decoration and building structures. As we all know, compared with the previous stainless steel, the advantages of industrial aluminum profiles are that they will not be oxidized and blackened, but sometimes they will become black due to improper use. Here are a few reasons.

1. External factors, because aluminum is an active metal, under certain humidity and temperature conditions, aluminum is easily oxidized, blackened or moldy.

2. Due to the strong corrosive nature of the cleaning agent, if used improperly, it will cause corrosion and oxidation of aluminum profiles.

3. After cleaning or pressure inspection, if the aluminum alloy material is not handled properly, it will create conditions for the mold and accelerate mold.

4. Many manufacturers do not perform any cleaning treatment after the processing process, or the cleaning is not thorough, leaving some corrosive substances on the surface, which will accelerate the mold growth of aluminum profiles.

5. Different storage heights in the warehouse can also cause oxidation and mold.

In short, there are many reasons for mold and blackening of industrial aluminum profiles. During normal use and maintenance, we only need to pay attention to the above reasons.
