Of course, the same type of profiles can also be put together for comparison, of course, if the color difference is too obvious, it is better not to buy. Check whether the cross-section thickness of the alloy aluminium sheet is the same as the model marked.


3. A smooth hard object can be used to scratch the surface of the aluminium alloy sheet, leaving a white scratch. The aluminium alloy sheet can be gently wiped and observed by hand. If it can not be wiped off, the quality of the material may be problematic. On the contrary, if it can be easily wiped off, the oxide film thickness on the surface of the profile is qualified.
