What should you pay attention to when buying aluminum composite panels?

  • Check out if the thickness meets the requirements, and if necessary, measure it with a vernier depth gauge. A magnet should also be prepared to check whether the selected plate is iron or aluminum.
  • Check out whether the surface of the aluminum plastic plate is smooth, whether there are ripples, bubbles, defects, scratches.
  • Break off the corner of the aluminum plastic plate at will, if easy to break, it is not PE material, or it is adulterated with counterfeit materials;Then you can use a lighter that you carry with to burn it. If the real PE should be completely burned, there will be impurities after burning with fake and shoddy materials.
  • Take two pieces of aluminium plastic sheet samplesto scratch each other a few times, see if drop lacquer. The aluminum plastic with good surface painting quality adopts the imported hot-pressing spraying process. The color of the paint film is uniform, the adhesion is strong, and it is not easy to remove the paint after scratching.
