Aluminum Trim Coil FAQ

  • Q What is the difference between aluminum trim coil and PVC trim coil?

    A PVC trim is made from a honeycomb, cellular structure of polyvinyl chloride. 
    Aluminum Trim coil is a thin sheet of aluminum covered with a water-based paint coating used to cover the exposed wood trim on a home. The core material and the surface material are absolutely different with each other.
  • Q How to save the retains of the aluminum trim coil left in stock?

    A If the aluminum coil suddenly changes from a low temperature area to a high temperature area during storage, do not open the package immediately, because the aluminum coil may have oxidized at this time. You should wait for the aluminum coil to be used before unpacking it to avoid oxidation.
    If there is rain or snow leakage in the warehouse, it is not suitable to place aluminum coils, because this may cause oxidation of the aluminum coils.
    Make sure the storage environment is ventilated and dry, and avoid storing aluminum coils in humid places. Aluminum coils are non-ferrous metals. If they come into contact with water or are in a humid environment, they are easily oxidized. White oxidation marks will form on the surface, causing damage to the appearance. In severe cases, they cannot be used. Therefore, a dry environment is a necessary condition for storing aluminum coils.
    The above are some suggestions for preserving and collecting aluminum coils. If you still have questions, it is recommended to consult professionals.

    Use auxiliary tools: In order to make cutting more accurate and convenient, you can use some auxiliary tools, such as steel rulers, cutting mats, etc. When using these tools, you need to pay attention to the contact surface with the color-coated aluminum coil to avoid damaging the coating.

    Clean the cutting surface: After cutting, the cutting surface of the color-coated aluminum coil needs to be cleaned to remove burrs, impurities, etc. to ensure the effect of subsequent processing or use.

    In short, when cutting color-coated aluminum coils, you need to pay attention to the stability of the coating, control the cutting force, use appropriate tools, pay attention to cleaning, etc., to ensure the cutting quality and subsequent use effects.

    *Consider of sone uncontral conditions
    Aluminum expands and contracts with temperature changes. When installing, leave a small amount of space at the ends of the trim to account for this adjustment. Not doing so could cause the trim to warp or buckle.
    Make sure the aluminum trim coil in place using aluminum or stainless steel nails because they won't corrode. Remember don’t make the nails so tightly, the aluminum trim material should be able to move slightly to accommodate expansion and contraction.
