Sustainability, upcycling, downcycling, landfills … the list goes on! What is one to think when every material is touted as sustainable? Don’t believe me? Visit any material website; for example, cement/concrete, vinyl plastic, wood building products. What is one to make of all these claims—are they real? How does our industry fit in?Continue reading
We begin with two strange words, which in some ways are opposites—and in other ways are similar.
Welcome to the fascinating world of wetting.
First, let’s keep this simple. Let’s only think about water—as opposed to oily materials—that is deposited onto coatings, windows, mirrors, the leaves of plants, etc. The water (in the form of rain, steam, fog, etc.) may form droplets on the surface, or it may spread into a thin film. A hydrophobic substrate causes the water to form droplets; a hydrophilic coating, however, causes the water to spread into a thin film. But how do you keep these two terms straight, given that they sound so similar? Continue reading
I know you had a 30-year warranty, but—after 15 years—those shingles simply must be replaced. Anyone can call a roofer, but why not take a shot at making your own shingles? But first you need a formulation—the recipe—and I’ve got just the one for you. And while we’re at it, let’s compare shingle manufacturing to metal roofing manufacturing.
Prescriptive Requirements vs. Performance-Based Testing in the Construction Market
Sometimes your doctor writes a prescription for your ailment, and sometimes your doctor wants to run some tests first. The first example is a prescriptive approach (do this and you will be okay), whereas the second example is a performance-based approach to solving your problem (take some meaningful measurements and then determine what to do). The same two options are also used in the metal building industry.
Announcer: There is nothing wrong with your television set. Do not attempt to adjust the picture. We are controlling transmission. We will control the horizontal. We will control the vertical. We can change the focus to a soft blur or sharpen it to crystal clarity. For the next hour, sit quietly, and we will control all that you see and hear. We repeat: there is nothing wrong with your television set. You are about to participate in a great adventure. Continue reading
About 75% of the North American coil coating industry is dedicated to building products. Since the lifetime of these products is measured in decades, as opposed to merely years, the weathering performance of the coatings used for this market is critical. Understanding how coatings perform, therefore, is essential. There are many approaches to studying weathering performance, and one of the more interesting techniques to accelerate the weathering process involves the devices described in these two ASTM standards:
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
