Solanum Steel is a next-generation preweathered weathering steel surface that offers rich earth tones and enduring beauty. It is available as a flat sheet good or for specification within a Zahner project.
Solanum offers a deep red to purple color and the rugged textures of a steel that has endured years of exposure to the elements without the wait.
Preweathering the steel also mitigates the unsightly rust runoff and staining that accompanies natural oxidation.
Solanum Steel is a stylish choice that opens new opportunities for artists, architects, and designers.
Solanum Steel outperforms conventional weathering steel by undergoing a multi-stage preweathering process that accelerates the transformation of the base steel alloy.
The resilience of this pre-weathered surface presents novel prospects to harness the strength and allure of weathering steels in previously inappropriate applications. Solanum’s stabilized and colorful patina provides a resilient surface that protects the underlying steel from the corrosive effect of water and other elements.
When using Solanum Steel for interior spaces, a clear coating can be applied to the material to create a smoother texture. For exterior applications, it is advisable to leave the material unsealed.
See Solanum Steel in application through a selection of Zahner projects.
