MCA conducts many technical studies and research projects in partnership with member and industry partners. These studies include bulletins, white papers, manuals and reports that ensure that metal is at the forefront of innovation, and proactive with codes and standards.
This technical bulletin is intended to be a guide to proper fastening of metal panels to wood or metal frame buildings. The selection of the proper tools for the fastening of metal roofing panels is critical for ease of installation, proper watertight sealing of the building, and the integrity of the connection.
Many uncontrollable factors contribute to oil-canning and no panel manufacturer, fabricator, or installer can assure the total prevention of oil canning on any given project. With careful attention to the production, material selection, panel design, and installation practice, the tendency for oil canning can be minimized.
The purpose of this manual is to familiarize personnel with the general knowledge, basic operation, safety, and maintenance procedures followed by standard trouble shooting suggestions for standard portable roll-forming processes. It is merely a general guideline. If questions arise about your specific portable roll-forming equipment and solutions cannot be found in this manual, contact the Original Equipment Manufacturer (OEM) of your roll former.
The information provided is intended to serve as a guide for the application of field applied air-dry paint systems used in small areas where the factory applied paint systems may be scratched or marred during the construction phase of a project. MCA does not condone or endorse the use of field applied air-dry paint systems and ultimate acceptance of such field work is at the discretion of others. Air-dry (touch-up) paint systems are essential tools to be utilized when completing building construction.

When ordering a coating (finish) for the building panels, you would think that the biggest choice would be color. Not true. There are many differences between panel coatings. Characteristics like color and gloss are easily spotted. Others like film thickness, adhesion, and resistance to change are more difficult to identify. It can take a coatings expert to know all of the in’s and out’s of coating performance. Fortunately, there are a number of very good publications available to the public that discuss performance and what to expect from several of the popular levels of panel finish.
Profiled metal roof or wall panels rely upon mechanical fasteners to secure the components to a structure. It is very important to select the correct type of fastener for metal construction in order to ensure a strong and weather-tight attachment. This Technical Bulletin serves as a guide for the selection of exposed fasteners used with metal roof and wall panels.
The use of copper-containing preservative-treated lumber in direct contact with certain metal products could lead to accelerated corrosion and affect the long-term integrity and performance of a metal roof or wall system. The most effective way to avoid corrosion is to ensure that the treated lumber used is either manufactured using the newer metal-free preservatives, micronized copper treatment or that there is a separation between the metal roof or wall panel and the preservative treated wood with some type of barrier material.
