For this project, we created custom corten steel panels for a modern fireplace, structural columns, and a bold front door with handmade corten handles. Normally, corten steel takes up to 4 years to develop its signature reddish patina. Using our custom acid treatment, we achieved the same rich, weathered look in just a few weeks. The result is a timeless, high-end finish with a raw, industrial edge — ready from day one.
