Brandner Design custom steel utility closets are engineered with a structural interior frame clad in steel and cross breaks in the doors for added structural integrity. All hinge and locking hardware used is stainless steel while the exterior cladding and doors are available in Stainless Steel and Hot Rolled steel. Stainless steel finish options include sandblasted black or bronze, as well as weathered black or bronze. Hot rolled steel is available in either a raw hot rolled finish sealed with wax/oil, or a pre-rusted finish also sealed with wax/oil. We do not recommend using an acrylic sealer on any exterior panels. Hot-rolled panels are subject to rusting depending on exposure and climate. Brandner Design Utility Closets are offered as a custom product per sizes and configurations needed per application.
