Rust kills steel, but it benefits weathering steel. Another term for weathering steel is Corten steel. The American Institute of Steel Construction refers to this type of rust as the useful corrosion. The great thing about Corten steel is that its lifecycle increases when it is exposed to the elements. Moreover, it saves a lot of money as you won’t need to paint the steel over and over again. Let’s know some great benefits of weathering steel.
Corten is Trademarked by the USS
Corten was trademarked by the widely known USS. Originally, it got the ASTM A242 standard, and is also appreciated by the latest ASTM grade for coils and sheets made of steel. This standard is known as A606. This type of steel was made with silicon, nickel, chromium, phosphorus and copper. When exposed to the elements, these ingredients allow the steel sheets to produce a fine layer of rust, which gives the impression that the steel sheets have been repainted recently.
Exposure to the elements
Traditional steel loses its strength when exposed to corrosion, but Corten gets stronger when it is exposed to the weather. The sheets form a layer of beneficial layer when they come into contact with oxygen and moisture. So, this is one of the major benefits of Corten.
The strength of the weathering steel is also very high. Plus, they require less maintenance and save you a lot of money. All of these benefits make this type of steel an ideal choice for the construction of roofs, bridges and buildings with open frames. As a matter fact, history tells us that bridges constructed with the weathering steel stand the test of time for as many as 120 years without requiring a lot of maintenance. So, these bridges don’t need to be regularly checked or inspected.
The look of the Corten is another thing that makes it so popular. Buildings constructed with this steel look reddish, just like rust. As the exposure to the elements continues, the steel starts to have a russet patina, and most people find it very beautiful. So, the rust looks beautiful and doesn’t look ugly in any way.
To cut a long story short, Corten steel is popular among a large community of engineers and architects. And the reason is that it offers a lot of advantages over the traditional steel. This steel is arguably the strongest steel that is able to stand the test of time and doesn’t require a lot of regular upkeep. Moreover, buildings built with the Corten don’t need to be painted, which is a great thing for the environment as well. And the biggest of the benefits is that you save a lot of bucks, as you don’t need to pay to the professional to inspect the buildings on a regular basis.
So, these are a few benefits that shed some light on the importance of the Corten. If you are planning to order steel sheets for your upcoming construction project, do give a go to this type of steel. Hopefully, you won’t regret your decision and recommend it to your friends as well.
