Areas that have salt-laden air, high rainfall, humidity or persistent fog are typically not the proper environment for Corten and even less so for bare steel. In addition, when using Corten or bare, cold-rolled steel it is important to use a minimum of 22-gauge steel. However, there is no warranty and anything that rust equals rust stains. Corten and bare, cold-rolled steel cost less and normally look nicer. The trade-off is that they cost a little more and they may not look as authentic as the real thing. Paint Prints arrive looking weathered, there are no rust stains, and there is a paint warranty. These three products each have unique advantages and disadvantages. Paint Prints normally consist of painted panels that try and replicate an orange/brown rusted appearance, a faded dull galvanized appearance, or a patinaed copper. In many instances, a paint print will try to replicate a naturally occurring patina. The paint line applies a base coat of solid color on the coil and then the coil runs through a second time with a different color using a special engraved paint roller that creates a pattern on the coil. Also known as Paint Prints, it is a product that has been painted repeatedly giving the finish depth and uniqueness. Painted products that look old and weathered are the best alternative for an instant rustic appearance. Corten steel will have a substantially longer life span than bare, cold-rolled steel. In simple terms, the steel is allowed to rust and that rust forms a protective coating that slows the rate of future corrosion. Weathering steel has increased resistance to atmospheric corrosion when compared to bare, cold-rolled steel.Ĭorten resists the corrosive effects of rain, snow, ice, fog and other meteorological conditions by forming a coating of dark brown oxidation over the metal, which inhibits deeper penetration and negates the need for painting and costly rust-prevention maintenance over the years. Weathering steel, best known under the trademark Corten steel or ASTM A606-4, is a group of steel alloys that were developed to eliminate the need for painting, and form a stable rust-like appearance when exposed to the weather. Letting the steel patina naturally is the best method for a beautiful rusted roof. The chemicals can also decrease the life span of the steel depending upon the method used to prerust it. There are chemicals sold that will rust the steel quickly, but it is a labor-intensive process. This is especially useful for interior applications and customers who want instant results. There is also an option to pre-rust the panel prior to installation. It will continue to rust throughout the life span of the product and the patina will develop further. After about three months it will have a fair amount of patina. Bare steel will start rusting immediately when it gets wet. When the steel arrives on-site it has a dull gray appearance and will weather with exposure to the weather. It does not have a galvanized or Galvalume substrate. Cold-rolled Steelīare, cold-rolled steel is simply uncoated steel. There are three ways to accomplish this look: bare, cold-rolled steel, Corten and Paint Prints. This type of metal is especially popular in desert and mountain communities for both residential and commercial applications. One of the more recent trends in architecture has been new roofs and walls that look 100 years old.
