Copper and zinc panels are generally unfinished allowing them to develop a natural patina which is both a protective layer and an aesthetic contributor. Preformed metal wall panels are manufactured from a variety of metals, including steel, aluminum, copper, and zinc. Since it is more common to use uninsulated metal panels over an insulated wall assembly, this article will focus on preformed metal panels that are used in this way.
Insulated metal panel systems are generally comprised of an exterior weathering panel and an interior liner panel that is filled between with rigid insulation. Preformed metal wall panels are available in either insulated or uninsulated versions. Photo courtesy of Petersen Aluminum / PAC-CLAD Metal wall panels are an increasingly popular choice for exterior wall skins due to their versatility and range of profiles, colors, and design possibilities. All of this has contributed to a market trend where metal wall panels are currently used in greater quantities than metal roofing panels. As a result, the emergence of new product choices has allowed preformed metal wall panels to become a familiar part of mainstream commercial building design, and even some progressive residential buildings. At the same time, new developments in coating technology allow longer life spans for the finished coating as well as the metal panels. This includes more choices in panel profiles and sizes allowing more choice and flexibility when considering metal panels in the design of a building. The MCA has pointed out that recent improvements in the metal panel manufacturing process have resulted in a wider selection of metal panel products.

Together, they advance industry-wide standards in metal panel fabrication and construction techniques as well as promote sustainable products and practices by its members.Ĭontinuing Education Use the follow ing learning objectives to focus your study w hile reading this month’s Continuing Education article. The industry trade group, known as the Metal Construction Association (MCA), views itself as a progressive organization that is supported by nearly 100 member companies, including metal panel manufacturers, coil coaters, distributors, fabricators, accessory and insulation producers, and contractors. Overview of Metal Wall Panels Metal wall panels are manufactured by a variety of companies in the U.S. In addition to meeting these basic design criteria, they have been proven over time in many different settings to be a reliable and sustainable design option. In many cases, where economy, longevity, and lightweight materials are part of the preferred criteria, metal wall panels are the favored selection.
