Coil coating is an effective and powerful way to increase the life, beauty and use of a product. This process can be used when you’re creating a home appliance, trim for architecture, building material or a container (to name a few of many uses.)

While the coil is being manufactured, coil coating (or toll coating) is the process by which the manufacturer applies a chemical or paint, typically to steel or aluminum, which are created as large rolls of coil prior to final forming.

The coils are bathed through layers of different products using multiple rollers. This is best accomplished in coil coating machinery, such as Black Bros. Vertical Coil Coater. During the coating process, the coils are opened, cleaned and treated so they can best retain the application of a final chemical or paint finish.

First, the chemical cleaning treatment helps form a surface that allows the final chemical or paint finish to adhere to the surface of the coil. The next step is to apply primer in the Primer Coater, which is followed by a trip through an oven to dry the primer. The last layer is applied in the Finish Coater, which rolls the lasting paint or chemical sealant that will form on one or both sides of the coil. The last step is rerolling the coil, which is then distributed to be machined into various products, such as refrigerator’s, garage doors, appliances or furniture.

One great benefit of coating is that the coat lasts longer when applied in a controlled factory setting with a Vertical Coil Coater – onto the virgin coil – than when it is applied after the final product is manufactured, when it’s impossible to replicate the powerful steps in the coil coating process.
