When purchasing aluminum profiles in the market, you should not only pay attention to the manufacturer's conditions, but also pay attention to the quality of the products. Unqualified aluminum profiles will reduce the quality of our engineering construction and even affect its function. So in the market, what are the key conditions for unqualified aluminum profiles?

1. There is a problem with the ingredients. Everyone knows that the key material of aluminum profiles is aluminum. If products other than aluminum, such as iron, are added to the manufactured products, their characteristics will be greatly discounted, which will result in non-conformance.

2. Difficulties in the processing process, such as the generation of bubbles during smelting, then the formed aluminum profile will have the actual effect of being fake and inferior, and even impossible to apply.
