In late March, the Sun crosses the equator and begins to move into the Northern Hemisphere. (We know that the Sun is stationary and Earth is moving, but it is easier to think about it the other way around.) Temperatures rise, perennials bloom, and we’re glad that winter is over. It’s a great time of year. The heavy coats go back into the closet and everyone’s attitude brightens. But we all know those warmer spring temperatures will eventually turn downright hot in summer. Some say it’s getting even hotter due to global warming. A prepainted product is on the market that can help mitigate environmental concerns raised by increasing temperatures. It’s called cool roofing and it continues to rise in popularity.
Coil-coated prints are the buzzworthy shortcuts of sophisticated metal product design. From delicate veining to enchanting shimmer, this coating technique takes color and effects to new heights and depths.
We live in a colorful world filled with pattern, texture, sheen, and shimmer; with architecture and design at the forefront of social media, television, and magazines, visual inspiration is everywhere. Innovations in coil coatings have made it possible to attain almost any aesthetic on prepainted metal. Woodgrain? No problem. Brick? It’s been done. Marble? Yep, it’s viable too! Thanks to the process of coil-coated printing, all of these designs are possible.
Coil-coated printing involves layered inking to create a distinctive pattern or design, such as stone, patina, brushed metal — the list goes on. Commonly used for wall panels, roofing, and garage doors, coil-coated prints are most famously known for their building and architectural applications, but they’re also used for appliances and specialty applications like entry doors, pool liners, and metal storage shacks. As a popular alternative to substrates such as wood, stone, and natural metals, they can achieve a combination of desired aesthetics and exceptional durability.
Pine trees are ubiquitous in the U.S. They are fast-growing, adaptable to many climates, and mark the Christmas season with their beauty and the smell of pine. But there is an aggressive streak that lies within!
An issue, prevalent in but not limited to the U.S. Pacific Northwest, is the accumulation of pine needles (also called “pine straw”) on prepainted metal roofing. Although metal roofing is better than asphalt shingles when it comes to shedding leaves, twigs, pine straw, and other debris, there will be occasions when build-up occurs. See an example below:
Prepainted metal not only offers an impeccable finish and endless color and design options, but it also offers an abundance of functional properties. Coil coated metal can be made weatherproof, corrosion resistant, UV resistant, antibacterial, and even smog-eating. It’s more than just steel or aluminum coated with paint. It is the result of multiple layers of state-of-the-art coatings chemistry plus an application process that provides durability and unique properties not possible with traditional coating methods. The following are some of the key properties of prepainted metal:
Telltale Signs You Need to Consider Prepainted Metal
If you are a manufacturer who post-paints articles in-house, you may be wondering if there’s a better way to get the painting job done. If you are reading this as a member of the coil coating industry, and you will surely encounter manufacturers that are post-painting, for whom you wish to introduce the concept of prepainted metal, this article is also for you. Read on to learn why.
Manufacturers have long benefitted from the speed, precision, and non-polluting aspects of using coil coating lines to make prepainted metal panels. Some manufacturers, however, utilize a coil coater’s capability beyond the painting process. Here are three ways manufacturers benefit from using coil lines as an effective first-step operation beyond prepainting.
Quantifying the color of an object, and then measuring color difference between the object’s color and a color standard, is an important factor in assuring color consistency and acceptance. Assembling parts from various lots and production runs requires that parts have minimal—or no—color difference, so a typical observer sees nothing objectionable.
Typically, a color instrument will deliver color values represented by three color coordinates:
“L” value, which describes the lightness or darkness of a sample
“a” value, which describes the redness or greenness of a sample
“b” value, which describes the yellowness or blueness of a sample
The old saying, “As exciting as watching paint dry” could not be further from the truth when it comes to coil coatings. First, the paint that is applied to a metal coil during the coil coating process dries (bakes, really) in just 15 to 30 seconds. A lot takes place in that short period of time: 1) the solvents evaporate (they are captured and destroyed in this environmentally friendly process), 2) the coating flows to produce a smooth surface, and 3) a chemical reaction takes place to create a cured, hard, scratch-resistant yet flexible coating. To the chemists who create this magic, it’s exciting stuff, but it’s difficult for the consumer to appreciate since the process takes place in a factory setting. What consumers can appreciate is what they see when the product reaches the marketplace. So … let’s see what’s innovative these days!
First, let’s talk about beetles. Yes, beetles. Especially the ones that have that cool iridescence. They create that effect by … well, it’s complicated!
A nationwide study by Berkeley Lab details benefits of lighter-colored, solar-reflective walls
As you likely know, NCCA members and their customers along the prepainted metal value chain have been supporters of “cool roofs” for 20 years. Without question, this technology effectively reduces energy consumption during the hot months of the year. So, what’s next?
“Cool walls”! Wait, what? Cool walls? Cool-roof technology is intuitive; roofs face the sun, but walls are vertical structures. How much solar energy can they possibly be exposed to? Well, you’ve come to the right place to find the answer.[i]
