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.

Part One (of Three)
When you look at a piece of prepainted metal, what do you see? Certainly a colorful article that may or may not have some shape to it. Often the metal is fabricated with “ribs” to add structural strength to the panel, or it may be flat, as is the case with a metal composite material (MCM) panel. The surface of the prepainted article might be a smooth, homogeneous surface, or it may have a wood-grained pattern, or it might have a subtle pebbly texture. The color of prepainted metal ranges from whites, grays, and blacks to neutral earth tones to saturated, brilliant colors. Some of the colors have metallic or color-shifting effects. But this layer of color is only what you actually see. What you don’t see is all that is under the surface. Continue reading

Chances are, if you’re reading this blog regularly, you already know that prepainted metal is the substrate of choice for metal buildings, HVAC products, appliance products, and more. The list of applications for prepainted metal is endless, as are the reasons why prepainted metal is the substrate of choice for so many products. To be honest, this long list of reasons is not the subject of today’s post, save one: aesthetics. So many beautiful colors! Color and texture can make blockbusters out of the ordinary products we take for granted. In addition to the performance benefits of prepainted metal, its almost limitless beauty is quickly rising to the top of the list of reasons why consumers choose it for any number of applications. But then tradition steps in and says, “You can’t use metal here, it has to be wood!” Well, phooey. Now what? Continue reading
In NCCA Tool Kit # 26, “Factors Influencing the Long-Term Performance of Prepainted Metal Building,” an emphasis was justifiably placed on the selection of materials. That selection process starts with a substrate that must provide the corrosion-resistant properties for the environment in which the prepainted product will be used, probably for decades. Whether the specifier is considering steel or aluminum, the mechanical properties of the material are of paramount importance. After all, all prepainted metal is post-formed, so the substrate, as well as the paint system, must be able to withstand the rigors of the fabrication process. With a steel substrate, it’s the thickness of the metallic coating layer; with hot-dipped galvanized steel, it’s the zinc; and with Galvalume®, it’s the Zn-Al metallic blend that needs to have an adequate thickness to provide the necessary lifetime and level sacrificial of galvanic properties. There are many parameters to consider. Continue reading
It seems so simple: We cut a finger or bruise a knee, and a week or so later we’re all better. You snip a small branch of basil leaves to make pesto, and before you know it there is another branch of basil leaves sprouting from the cut. If plants and animals can heal and thrive, why not other organic material, like polymers used to make coatings?
These days, it’s not uncommon to hear businesses from nearly every industry discuss “sustainability” or plans for a more sustainable future. As the term becomes more ubiquitous in today’s business planning, its definition can be somewhat vague. For our purposes, sustainability refers to a company’s efforts in reducing its environmental impact through the use of more environmentally-friendly building materials and less consumption of natural resources. While the coating industry works diligently in manufacturing products that adhere to high standards for sustainability, there are several ways to be more sustainable and environmentally conscious.
1. Reduce the use of volatile organic compounds.
For a long time, volatile organic compounds, or VOCs, played a large role in the coating industry because they contain properties that assist in applying coatings to a surface. Continue reading
Year after year, the coated metal industry continues to innovate and inspire designers and architects with new aesthetical and color options that have reshaped consumer expectations. More than ever, buildings have the ability to stand out, while reaping the durability and environmental benefits of using prepainted metal. Here are just a few of the latest trends in coated metal that define why there’s never been a more exciting time in the industry.
1. Textured Products
Textured, painted metal products were introduced in the 1980s to expand the visual, durability and eco-friendly possibilities of incorporating these products into commercial and residential applications. Continue reading
