Ever wondered why corrugated metal panels are so popular? These versatile materials, including aluminum corrugated panels, offer strength and aesthetic appeal. In this article, you'll learn about their importance, history, types, and applications.
History and Evolution of Corrugated Metal Panels
Corrugated metal panels trace back to the 1830s in England. Henry Robinson Palmer invented the first corrugated steel sheets around 1829 to 1830. He designed these panels to be lightweight and strong, making construction faster and more affordable. The wavy pattern, or corrugation, added strength by increasing the metal's rigidity without adding much weight.
In the early 1900s, corrugated metal panels gained popularity in the United States. In 1912, the Trachte Brothers in Wisconsin patented a roll-forming machine to produce corrugated steel panels for livestock water tanks. By 1919, Arthur Trachte used these panels to build a garage for his Dodge automobile. This garage caught attention, leading Trachte to sell garage kits made from corrugated steel.
Over time, corrugated panels evolved from simple utilitarian products into versatile building materials. They became widely used for roofing, siding, and even interior design. Their classic wavy look remains popular, especially for agricultural, industrial, and rustic-style buildings.
Modern corrugated panels come in various rib heights and widths. For example, Multi-Cor panels have bold ⅞-inch ribs, while M-Cor panels feature more subtle ½-inch ribs. This evolution offers different aesthetic and structural options to suit various projects.
Despite newer metal roofing profiles with advanced features like anti-siphoning channels, the original corrugated panel design endures. Its simplicity, durability, and nostalgic appeal keep it relevant. Proper installation techniques, such as applying butyl sealants at laps and using solid decking underlayment, help prevent leaks and extend panel life.
Today, corrugated metal panels remain a cost-effective, flexible solution for builders. Their history shows a continuous journey of innovation balanced with timeless design.
Note: When specifying corrugated panels, remember their rib height and width affect strength and appearance, influencing project suitability.

Manufacturing Process of Corrugated Metal Panels
Corrugated metal panels are made through a precise manufacturing process that ensures strength, durability, and consistent quality. The two main steps involved are the roll forming process and the application of coatings and finishes.
Roll Forming Process
The roll forming process shapes flat metal sheets into the classic wavy profile of corrugated panels. Here's how it works:
Metal Coil Feeding: Large coils of metal, such as galvanized steel or aluminum, feed into the roll forming machine.
Progressive Rollers: The metal passes through a series of rollers that gradually bend it into the corrugated shape. Each roller station forms part of the wave or rib pattern.
Cutting to Length: Once shaped, the continuous metal sheet is cut to the desired panel length using a shear blade.
Quality Control: Panels undergo inspection to ensure rib height, width, and overall profile meet specifications.
This roll forming technique allows for continuous production of long panels, which can be customized in width and length depending on project needs. It also helps maintain uniformity in rib spacing and panel thickness, critical for structural integrity and appearance.
Coating and Finishing Options
After roll forming, panels receive coatings and finishes to protect against corrosion, enhance aesthetics, and extend lifespan. Common coating processes include:
Galvanizing: Applying a zinc layer to steel panels for corrosion resistance.
Galvalume Coating: A mix of aluminum and zinc that offers superior rust protection, especially in coastal or industrial environments.
Paint Finishes: Panels may be painted with durable, weather-resistant coatings. These come in many colors and finishes, including matte, gloss, or metallic.
Clear Coatings: Some panels receive a clear protective layer to preserve the metal’s natural look while preventing oxidation.
These coatings not only protect but also improve energy efficiency by reflecting sunlight, reducing heat absorption. Many manufacturers offer custom color matching and specialty finishes to fit architectural styles.
Tip: When ordering corrugated panels, specify the exact coil width and finish type to ensure consistent lap patterns and optimal weather resistance for your project.
