Brandner Design Patina finishes

The Patina Art

Patinas result from a reactive process of applying acids to steel and common alloys to create completely original designs, colors and textural finishes. For 15 years, Brandner Design has been leading the architectural trend of using these unique artistic metal finishes in both commercial and residential spaces across the world.

The Patina Craft

Every metal surface and acid finish has its own method, and with our 15 years of experience creating patina finishes, we have mastered an extensive palette of colors.

Through an artistic use of acids, heat, humidity, time and experienced craftsmanship, the finished product will feature timeless colors, textures and designs and can be applied on steel (and stainless steel), copper, brass, bronze and zinc. All our patina’d products are sealed with a hand rubbed wax, acrylic urethane or a clear powder coat and can be used for interior or exterior applications.

The Artisans

We’re committed to creating timeless and signature architectural works of art in metals, wood, glass, concrete, leather and acrylics. Everything is designed and built in our 33,000 square foot studio in Bozeman, MT— a state-of-the-art facility featuring a complete millwork, cabinet shop, metal fabrication, Trumpf fiber laser and CNC brake, finishing department and design studio. Staffed with 35 woodworkers, metal workers, artisans, architectural designers and engineers, we thrive by solving complex problems and continually reinventing what’s possible in the design world.

An Acid of Many Colors

Custom finishes are also available.

Begin by visiting the gallery section to sample design and color palette options. Our staff of drafts people and designers will help with layout, choice of material, finish and engineering of installation. We will meet the needs of whatever our clients want to create and offer advice if there are unknowns.


Parts are custom laser cut per order and formed by True Cut Laser, a division of Brandner Design, and are prepped with countersunk holes for face screws or glued to a substrate to receive a z-clip hanger for a hidden fastener.
