A well-made custom metal sign can sometimes last between 15 and 25 years, and in many cases considerably longer, depending on the metal type, finish and where it’s installed. Stainless steel and Corten steel are particularly long-lasting thanks to their natural resistance to corrosion, while painted or powder-coated metal signage can last just as long provided the coating is applied correctly during manufacturing. Indoor metal signage, such as reception plaques or boardroom nameplates, tends to last even longer again, since it isn’t exposed to weather at all. The key factor in lifespan isn’t just the material itself but how the sign is made. At Bespoke Office Signs, every sign is designed, manufactured and installed by one experienced team, with the right fixings and finish chosen for its environment, which consistently outperforms signage assembled from mismatched parts or a rushed installation.
