Once the coating is gone, the steel ionizes, which makes it so the steel does not continue to rust and you won’t have to worry about the panel being rusted all the way through. Weathering steel is extremely resistant to corrosion caused by weather and other atmospheric conditions. It forms a textured oxide surface film on the panel and as time passes, and the panel is exposed to the different weather elements like rain or snow, it begins rusting into a unique patina-like color. The weathered steel finish begins with a top coat made of copper, phosphorus and silicon. As the finish is exposed to different types of weather, it begins to rust into a gorgeous, rustic look over time. Weathering steel creates an unbelievable, one-of-a-kind look. You may hear it referred to as a Corten or Truten A606, both of which are just different names used to describe the finish. Weathered steel is a finish that will be completely unique to every project, every time. In contrast, most shingle tear-off waste ends up as part of the building-related waste stream - up to 20 billion pounds per year.If you’ve been searching for the perfect rustic look for your metal roof or siding, weathered steel will take your expectations to a new level. 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.Due to the smooth, straight lines, these roofs give your house an "industrial" feeling, yet with a modern flair. Standing seam roofs are perfect for certain types of contemporary or country-style houses. 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.Fewer Seams - Because the metal panels run unhindered from the top to the bottom of the roof, not only are there no horizontal seams but, in total, the roof has a fewer number of seams.It allows for the full expansion and contraction of the metal. The clip is fastened to the roof deck so that the panels are allowed to “float.” This helps to ensure that the system will maintain its water tightness much longer, and also its aesthetics, as oil canning will be less of a concern. Weathertight – Clip fastened panels are one of the most durable and weathertight roof systems available.Moisture and water will be kept away from entering the interior of the building, and will make water run properly to the roof drains. Higher seams, also called “ribs”, are raised above the level of the roofing panel. High Seams – The weak point in any roof and a potential entry point for moisture are at its seams.
