However, galvalume provides more complex coverage and better overall corrosion resistance. Compared with galvalume, galvanized zinc provides increased edge and scratch protection while significantly reducing costs. Galvalume corrugated metal finish is manufactured from a 55% aluminum and 45% zinc coating substrate, making it lighter and more energy efficient than galvanized paneling. When combined with silicon, the aluminum-zinc galvalume finish bonds effectively to the steel substrate allowing for equal adhesion throughout the steel.Ĭonversely, a galvanized corrugated metal finish is composed of 100% zinc. Galvanized Corrugated PanelsThe main factor that differentiates Galvalume and Galvanized corrugated metal sheet lies in the material chemistry of each finish. Due to its enhanced durability and aesthetics, corrugated metal roofing has become increasingly popular over conventional roofing materials such as asphalt shingles and clay tile. It is low-cost, lightweight, durable, energy-efficient, long-lasting, and easy to install. The traditional shape of corrugated sheet metal is round and wavy. Is Corrugated Metal Used for Roofing Applications?Corrugated metal roofing products are designed to withstand all elemental and environmental conditions, including hail, snow, heat, wind, fire, and more. The steel’s corrugated configuration provides one of the highest strength-to-weight ratios of any construction material. The steel grooves increase the tensile strength, making it resistant to increased impact and weight loads. What are Galvalume and Galvanized Corrugated Metal Used For?Corrugated sheet metal and panels are manufactured through a cold-form process where they are pressed and roll-formed to create the desired corrugated shape. In contrast, most shingle tear-off waste ends up as part of the building-related waste stream – up to 20 billion pounds per year.What is Corrugated Metal?Galvanized and Galvalume corrugated metal sheet, are tough, lightweight, and weather-resistant materials that provide advanced protection qualities that cannot be matched by any other type of material. Corrugated steel sheet and panel products are among the most popular siding options on the market due to their excellent durability and easy maintenance requirements, providing beneficial results for various applications. Corrugated roofing panels are also recyclable at the end of their life as a roof. Eco-Friendly – Metal roofing is made from recycled content.Energy Efficient – Metal roofs with a “Cool” paint finish reflect solar radiant heat, which can help reduce cooling costs.Stylish – Available in various colors and can be ordered in a variety of premium specialty finishes.Lightweight – Lightens the load in installation and reduces the load bearing weight on support walls and beams. Wind Resistant – Metal roofing can withstand powerful wind gusts.Class C rating when applied over a combustible material such as wood shingles. Fire Resistant – Metal roofs are noncombustible and have a Class A fire rating.Pest and Termite Resistant – Bugs, pests, and termites cannot penetrate through metal materials making a corrugated metal roofing system your best defense against unwanted creatures.Rot Resistant – Since metal is an inorganic material, unlike wood, it does not rot – making it the best choice in roofing material by builders and architects alike.Durable – Metal Roofing coated with Galvalume®/Zincalume® will have an exceptionally long life expectancy.Corrosion and Rust Resistant – Our metal roofing and siding panels and sheet steel products are coated with Galvalume®/Zincalume® – an aluminum-zinc alloy coating with extraordinary outdoor corrosion resistance.
