Spectura Steel features a clear interference coating on steel that creates a striking iridescent effect. Colors shift and change as the angle of view or illumination varies, ensuring each sheet is uniquely vibrant. Ideal for controlled interior environments, Spectura enhances walls, lobbies, accents, and more with its captivating spectrum of color. Architects and designers can use Spectura to brighten entrances, modernize conference rooms, and bring colorful, artistic elements to interiors.
Discovered during an experiment for another project, Spectura Steel’s iridescent finish is produced with an environmentally friendly process that is durable and easy-to-clean surfaces using common glass cleaners. Manufactured in Zahner’s award-winning and EPA-compliant facility, the process incorporates advanced wastewater recycling and mitigation methods. This commitment to sustainability, combined with Spectura’s vivid, color-shifting appearance, makes it a standout choice for adding beauty and innovation to modern interior designs.
Spectura Steel Manufacturing, Properties, and Applications
Spectura was discovered by accident while working on 1700 Pennsylvania Avenue – The Mills Building with the renowned real estate investment and development firm Akridge. While experimenting with a darkened custom patina for zinc, one of the formulations produced a remarkable iridescent effect.

That formula was cataloged and tested further on larger sheets with various application methods and dwell times which were found to lighten or darken the iridescent effect depending on titration and timing. The solution used to create the effect does not contain any strong bases or acids, does not harm the environment, and the cured finish can be easily cleaned with common glass cleaners.
All Zahner Surfaces are manufactured to the highest standards of environmental protection and wastewater mitigation in our Grand Prairie, Texas facility. Our state-of-the-art wastewater ion exchange system recirculates and deionizes rinse waters from patina baths to remove residual minerals or solvents, allowing water to be neutralized and recycled, and dry waste to be kept to a minimum.
