At present, many family doors and windows and packaged balcony materials are made of various aluminum alloy profiles. Therefore, when you are shopping, be sure to look at the quality of the raw materials. In general, visual inspection can also make a preliminary assessment of the quality of aluminum profiles. The main methods of identification are as follows:
1. Check whether the profile thickness of the profile is consistent with the model. Profiles that do not reach the wall thickness cannot be used.
2. Check whether the aluminum alloy profile (6 meters long) has obvious twisting and twisting. If the twist is so severe that it is difficult to recover, it cannot be used anymore.
3. Check whether the surface of the profile is smooth; whether it has white spots, black spots; whether or not there are cracks, burrs, and peeling; whether there are obvious scratches or bumps.
4. It is not allowed to have different shades of different shades for the same aluminum alloy section;
5. The surface of the profile, gently scratched with a smooth hard object, will leave a white mark. If it can be wiped off by hand, the oxide film is not scratched off; if it cannot be wiped off by hand, it means that the oxide film has been scraped off and the quality of the material is problematic.
