As an association, the National Coil Coating Association (NCCA) has the ability to speak with one voice on any number of issues. The association is dedicated to the coil coating process: cleaning a metal substrate (aluminum, hot-dipped galvanized steel, etc.), chemically treating the substrate to enhance corrosion resistance and paint adhesion, priming the strip with a corrosion-resistant primer, and topcoating the strip with any number of materials designed to provide aesthetics and durability to the coil-coated metals used in the construction products, transportation, appliance, and HVAC markets.

It goes by many names: prepainted metal, coil coated metal, prefinished metal. Each of these descriptions refers to the product of a coil coating line, sometimes called a continuous coil line (CCL). Prepainted metal is commonly used as a coated product in construction applications (metal walls and roofs are two examples), as well as appliances, HVAC units (air conditioners, furnaces, etc.), rainware products (gutters, downspouts, flashing, etc.), and many others. Prepainted metal is the product; a CCL is the application process used to produce prepainted metal.
When it comes to making a home energy-efficient, the choice of roof can have a far-reaching impact on the overall sustainability of a structure. The right kind of roof makes a home’s entire energy infrastructure operate more efficiently, staying naturally warm in winter and cool in summer. This cuts down the need to augment temperature through heating or air conditioning and reduces reliance on the earth’s natural resources. Continue reading
With its nearly endless color and texture possibilities, eco-friendliness, and durability, prepainted metal’s popularity is on the rise when compared to other materials. With the technological demands of modern fabrication techniques, manufacturers may wonder if prepainted metal, despite its upward trending, can handle the rigorous processes of manufacturing, such as embossing and rollforming, while maintaining adherence to government regulations. They need not worry. Prepainted metal is proven to meet and exceed these requirements across the board. Continue reading
Manufacturers have long benefitted from the speed, precision, and non-polluting aspects of using coil lines to make prepainted metal panels. However, some manufacturers are unaware that coil lines can perform a variety of functions on metal coils, from reclamation to pretreatment to simply giving them a better-looking finish. Here are four ways manufacturers benefit from using coil lines as an effective first-step operation beyond prepainting. Continue reading
In Part One, we discussed The Hidden Strength of a prepainted metal system (the base metal, the metallic layer, the pretreatment and primer). In Part Two, we examined The Visible Beauty of prepainted metal: color, gloss, texture. Strength and beauty—not to mention durability and sustainability—are important features, but the coil-coating industry also offers The Functional Capability that sets prepainted metal apart from other products, and most of this functionality can be built into the coil-coated topcoat. This topcoat layer, compared to the base metal, is thin—about 2% to 4% of the total thickness of the prepainted article. But what an incredible layer it is! In addition to providing the aesthetic properties (color, gloss, texture, etc.), coil-coating topcoats can be formulated to provide many functional properties. Continue reading
In Part One, we discussed The Hidden Strength of prepainted metal. It’s easy to take for granted all that lies beneath the surface of prepainted metal: the cleaning and pretreatment of the base metal, the metallic coating, and the continuous process that prepares the metal strip for primer and topcoat, all in one pass through the coil coating line. Here in Part Two, we’ll learn about the only feature that is actually visible in a prepainted part—the topcoat; that is, The Visible Beauty. There is, however, more to it than meets the eye.
