For example, the simple, rounded lap does not contain any breaks or gaps that can help prevent leaks by inhibiting capillary draw. While the corrugated panel does allow for great flexibility, there are some limitations. Wider master coil will result in a wider Multi-Cor panel width which will affect standard lap patterns as shown below.įor more information about laps as well as other information, such as fastener patterns, please see our Multi-Cor and M-Cor Product Data Sheets. To illustrate further, let’s take a closer look at 26 gauge Multi-Cor, which can be manufactured out of 41 9/16” or 43” master coil widths. It is important however, to note that different panel widths will result in different lap conditions. This flexibility enables more options for substrate, colors, and gauges. Due to corrugated panels’ consistent rib configurations, panels can be manufactured in a variety of widths which is dependent on the coil size. Manufacturing flexibility is another hallmark of corrugated panels.

Panels are commonly installed as roofing panels, wall panels, interior accents, and liner panels. Versatility is another reason corrugated panels are popular.

Multi-Cor’s ⅞” high ribs are more pronounced/bold while M-Cor has a more subtle ½” high rib profile. McElroy Metal offers two corrugated profiles.īoth Multi-Cor and M-Cor feature the classic “wavy” ribs that identify corrugated panels. The appearance of corrugated panels can vary based on rib height and width. In fact, over the past 20 years or so, the use of corrugated panels has grown significantly as more and more people appreciate the classic and nostalgic appearance of old-style, corrugated panels.Ĭorrugated panels are classified as exposed fastener panels, which means they are attached via fasteners that penetrate the panels and attach to the framing or substrate below. However, the classic appearance of the early corrugated metal panel is still relevant and popular today. In those days, an 8’ x 16’ garage sold for $100.įrom those humble beginnings, a myriad of other roofing and siding panel profiles have been developed that offer different aesthetic appeal, greater strength, and improved weather-tightness. Arthur’s new garage garnered considerable attention from friends and neighbors, so Trachte started selling garage packages. In 1919, Arthur Trachte utilized corrugated steel panels to build a structure to house his new Dodge automobile. In 1912, Trachte Brothers, Co from Madison, WI designed and patented a roll-forming machine to manufacture corrugated livestock water tanks. Corrugated roofing and siding are widely recognized as the first metal panel profile to be developed and its origin goes back to England in the 1830s.
