Whatever Happened to … Acid Rain?

Air emissions and global warmingThis is the first in a series of posts under the general heading, “Whatever Happened to … ?” The idea is to revisit issues and opportunities of the past and help bring you up to date on what has been accomplished and what is still yet to be done. So … whatever happened to acid rain?

As it pertains to the prepainted metal market, and especially to metal roofing, acid rain became an accepted and understood phenomenon in the late 1970s and early 1980s. Badly corroded roofs were becoming more prevalent, but—like any new problem—it took some time to identify the root cause and to learn how to overcome the issue of red rusting on roofs. And, as with any root cause analysis, an early root cause declaration is usually challenged. Then more research is done, more challenges are raised, and, eventually, consensus is reached.

When “Just Right” Means “Uh-Oh”

nccaA while back, I wrote about the “just right” conditions necessary for the formation of fog. That particular post discussed the scattering of light, which is done by materials such as titanium dioxide (the principal pigment in white paint) and clouds (where water droplets do the scattering). The birds are chirping at sunrise and the vernal equinox has already passed, which means the sun is finally in the Northern Hemisphere and the days are getting longer and warmer—and all of this points to the beginning of another building season. That got me to thinking about a few other “just right” conditions that seem pertinent for this time of year. And, once again, water comes into play. Continue reading

Three Benefits of Prepainted Insulated Metal Panels

insulatedmetalpanelsArchitects and building owners continue to expand the use prepainted metal  for its long-term durability, specifically its excellent  chalk, fade, and adhesion performance. The use of Insulated Metal Panels (IMPs) is also on the rise in a variety of roof and wall applications due to its sustainability and versatility. Combining the two, prepainted IMPs provide  superior energy efficiency and durability, both of which are necessary  in today’s competitive marketplace to comply with ever-evolving building codes and customer expectations.

Prepainted metal is a popular choice for consumers, architects and specifiers who are looking for environmentally friendly, durable, and aesthetically pleasing options. The National Coil Coating Association’s (NCCA) members are seeing a growing trend for textured, prepainted metal products in commercial and residential building design.

While the use of textured paint in coated metal building products is often found in roofing applications for its environmental benefits, the visual and textural innovations of recent years have opened up textured products to a number of applications. Continue reading


Factors Influencing the Long-Term Performance of Prepainted Metal Buildings

Most metal buildings are made with prepainted metal building panels. The coil coating process used to make prepainted metal provides many benefits, including superior bonding of paint to metal, durability, environmental friendliness, etc. As a result of the use of prepainted metal, metal buildings are aesthetically pleasing, durable, long-lasting, and economically-efficient structures.

The long-term performance of metal building panels and metal buildings is influenced by three principal factors:

  • Choice of materials
  • Environment in which the products are placed
  • Variability of processescropped-header-980x2759.jpg

Securing Coils for Shipping and Related Requirements

The U.S. Department of Transportation, Federal Motor Carrier Safety Administration (FMCSA) provides specific requirements regarding shipping of products, including metal coils. The complete FMCSA requirements can be found in the Code of Federal Regulations. The following provisions of the code relate to securing cargo and safe loading:

  • Shifting or Falling Cargo: FMCSA, 49CFR393.100
  • Safe Loading: FMCSA, 49CFR392.9
  • Rules for Securing Metal Coils: FMCSA, CFR393.120

It is typical for shipping companies to properly secure cargo. Carriers assume responsibility for complying with DOT regulations, and coil coaters do not accept liability for the carrier’s responsibility to properly secure loads. Some companies require their carriers to acknowledge their familiarity with the federal shipping requirements and to agree to abide by the DOT regulations.

Some companies also include signs in their facilities to make drivers aware of their responsibility to be aware of the applicable regulations. An example of such a sign in a coil coating facility follows:

Notice of U.S. Department of Transportation Shipping Regulations: Continue reading
