Corten Steel is a great material for exterior commercial signs. The patina on the signs eliminates the need for paint and can last for decades with little to no maintenance. It usually takes up to six months for the sign to develop a full patina but this process can be dramatically sped up using a solution of hydrogen peroxide, vinegar, and sea salt.
With it’s vintage, rustic look and incredible strength it’s no wonder more and more people are choosing Corten for their exterior commercial sign needs.
