The AFP coil coating process produces prepainted, coiled metal for a diverse group of customers. The substrates used include cold rolled steel, hot dipped galvanized steel, galvalume, zincalum, and aluminum.

The coil coating process uses coiled uncoated (bare) steel or aluminum strip (up to 43" wide) as the feed material. The gauge range for steel products is .013" - .040"; for aluminum, it is .008" - .060".

We uncoil the bare metal strip and feed it continuously through the coating process. As the metal strip uncoils, it passes through a series of accumulation rollers that allow for inventory buildup. This ensures that the process can operate continuously during short term feed stoppages (such as when an empty coil is replaced with a full one).

The metal strip proceeds from the accumulation rollers through an aqueous cleaning process, a brush unit, and a two-stage water rinse process. Next, the rinsed strip is roller coated with a chemical coating/etching and then air-dried.

The dried metal strip material is then roller coated on both sides, dried in a convection oven and cooled before proceeding to the finish coat station. The finish coat is applied to one or both sides of the metal strip, it is then dried in a convection oven, cooled and rewound into coil form.

VOC's (volatile organic compounds) collected off the two ovens are directed to a thermal oxidizer.

If needed, we can also slit, roll-form, and package according to your requirements.

Here at AFP, we are currently coating hundreds of colors in a variety of paint systems (polyester, silicon modified polyesters, kynars, etc.) and can meet any customer color requirements.

AFP is a member of the National Coil Coaters Association.
