Spectura Steel is a pre-finished steel sheet with a thin, clear coating that acts as an interference layer on the base steel and creates a spectrum of color as the angle of view or the angle of illumination changes. It can be purchased directly from Zahner or specified in any project.
Spectura’s dynamic, color-bending coating adds an element of variability that ensures no two sheets are exactly alike. This brings visual attraction and interest to any project, offering beauty and durability for interior walls, lobbies, accents, elevators, and enclosures.
Spectura is excellent for interiors where humidity and temperature are controlled. It is perfect for architects and designers aiming to illuminate entrances, modernize meeting rooms, and invigorate interior spaces.
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.
Each Spectura sheet is one of a kind, with high variability in color patterning from sheet to sheet.
Use the visualizer to explore Spectura in a 3D environment. Rotate the object to see how the Surface will appear from different vantage points with a fixed light source.
