The metal sheet is rolled into metal panels to create corrugated metal roofing. Screws are then used to fasten these panels to the roof. The corrugated metal panel often has a circular, wavy shape. It is affordable, portable, strong, long-lasting, energy-efficient, and simple to install.

An appropriate replacement for clay or asphalt roof tiles is corrugated metal roofing. It applies to residential and commercial projects, including metal siding and roofing.

Corrugated Metal Sheets 101

Availability of Corrugated Metal Sheets

Almost every urban area in the country has access to standard corrugated roofing panels. The traditional use of thatch or banana leaves is already rendered absolute because of the advancements in construction materials. Using banana leaves and thatch are alternatives that are frowned upon by many homeowners. They are susceptible to fire and have a shorter life span.

Stronger, more durable choices like concrete roofing and clay tiles take a long time to make or are too expensive for even the smallest budgets. Standing seam metal roofing made of interlocking metal strips, interlocking metal shingles, or modular panels are also among the best metal choices.

What Is Corrugated Metal?

The term “corrugation” has historically been used to describe the unique “S” or “wavy” pattern formed and rolled into metal sheets. Through this procedure, the metal gains increased stiffness and flexibility to bend perpendicular to the ridges. Corrugating effectively maintains the thin, light profile of metal sheets while drastically boosting strength where it counts.

Moreover, experts say that the depth of the corrugations influences the strength of the panel; a deeper corrugation results in increased strength.

Available Sizes of Corrugated Metals

Corrugated metal panels are available in 1”, 12”, and 34”. These sizes denote the corrugation depth and the deeper the corrugations are the more structural resilience it has.

Variety of Metals Used in Corrugate Panels

  • Copper

Copper is exceptional but also pricey. Aside from having an identifiable sheen, copper has a lifespan of approximately 100 years, making it among the most excellent materials used in the roofing industry. After several years of exposure to the weather, copper changes its color to patinas or blue-green tint, which many people think increases its beauty.

  • Zinc

Here at Miami Metal Deck, we frequently utilize zinc, a fantastic metal roofing material. In general, metal roofing is widely employed worldwide, especially for commercial structures and historic roof renovations.

In addition to having exceptional corrosion resistance, a zinc roof has other benefits over conventional metal roofs. Zinc roofing does have a self-preservation characteristic, but it still requires little upkeep. You can install it and essentially leave it alone—even in a problematic location where it will be exposed to wind and rain.

Zinc has a more appealing look compared to some of the other metal manufacturers. Additionally, it can be shaped or molded into fascinating curves and designs while maintaining its durability. This feature dramatically appeals to architects because it is perfect for creating flashing around chimneys, dormer windows, and the central portion of the roof.

Zinc could be the solution for you if you never want to pay for a roof replacement again. A zinc roof’s natural patina, which shields the metal from corrosion, helps it to last more than 80 years. Like copper, many people also like the peculiar aspect of the patina, which develops a slightly bluish tint.  

  • Aluminum

A corrugated aluminum sheet is appropriate for roofing structures, making it a popular choice for roofs. It can function for a very long time in a challenging environment.

Some aluminum roofing sheets can include up to 90% recycled material. Hence, it is the ideal material for those who care about the environment. Because aluminum reflects sunlight, a building will stay cool in the summer despite rising temperatures. In the winter, it also aids in keeping the heat inside the house, conserving energy and lowering heating bills.

Although the initial cost may appear excessive, aluminum roofs can last up to 50 years and possibly even longer. Therefore, it is among the ideal materials to use if you want a long-term investment. Other roofing materials may only last 10 to 12 years; thus, replacing them up to five more times will undoubtedly increase the expense from the start.

The main benefit of aluminum is that it is another cost-effective option. Since it does not rust like steel, aluminum is the perfect or excellent material to use in humid coastal locations.

Aluminum is a superior metal to employ over an existing roofing material because it is lighter than steel. Because it is lightweight, this metal can reduce stress on the structure and make installation easier and quicker for the installers.

  • Galvanized Steel

In contrast to zinc plating, a thinner coat applied in an electroplating bath, the term “galvanized,” typically refers to a heavier layer of zinc applied to steel in a hot dip tank.

For items that will be exposed to extreme elements for an extended period of time, such as steel utility poles or street light poles with their mounting bolts and hex nuts, chain link fences with related posts and hardware, galvanized steel is ideal. Sheet metal for electronics enclosures and numerous screw fasteners with zinc coating is utilized in similar and other indoor applications.
