[China Aluminum Network] First of all, of course, is to look at whether the apparent appearance of aluminum profile distortion, touch the surface is smooth and smooth, there are no cracks or bubbles, scratches, burrs and other non-smooth place. If it is found, it is better not to buy it. This is the obvious point of quality problems.
Secondly, it is necessary to carefully check the surface color of aluminum profiles for the presence of color differences. A color difference means that the quality is off. Or you can put the same type of profiles together for comparison. If the color difference is too obvious, do not buy it. In addition, check whether the profile thickness of the aluminum profile is the same as that of the marked model, and whether there are any physical objects or labels.
Later, you can use a smooth hard object to scratch the surface of the aluminum profile, leaving a white scratch. We gently wipe and observe by hand. If it cannot be wiped off, it indicates that the material may have quality problems. If it can be wiped off easily, it means that the thickness of the oxide film on the surface of the profile is acceptable.
