There are a lot of industrial aluminum profile
in Guangdong. Guangdong has always been a key consumer in the building materials market. However, because industrial aluminum is not a mass consumer product, the general building materials market is not necessarily sold, so everyone is here. There is a relatively lack of awareness in this aspect. In this case, once a quality problem occurs, consumers cannot tell the cause, and it will be more troublesome to solve the problem. So how do we correctly choose industrial aluminum? Next, let's take a look together. First, check whether the section thickness of the aluminum alloy profile is consistent with the marked model; secondly, whether the aluminum alloy profile is obviously distorted, whether the surface is flat, whether there are white spots, black spots, cracks, burrs, peeling, or scratches. If there are traces, it is best not to buy; again, carefully check whether there are different shades of color on the surface of the same aluminum alloy profile. The color difference indicates that the quality is unreliable; then compare several profiles of the same model together, the color difference Obviously not suitable for purchase; finally, lightly scratch the surface of the aluminum alloy profile with a smooth hard object, which will leave a white scratch. Gently wipe the scratch with your hand. If it can be easily wiped off, it indicates the oxide film on the surface of the profile. If the thickness is qualified, you can buy with confidence; otherwise, the material may have quality problems. The above is the correct way to choose industrial aluminum. Have you got it?
