Forma Steel Weathering Steel.
An unique steel accent for commercial & architectural applications
Weathering Steel is a high-strength, low-alloy steel with improved atmospheric corrosion resistance. With Weathering Steel, the specific alloying elements in the steel produce a stable rust layer that adheres to the base metal and is much less porous, producing a better resistance to corrosion. The rust ‘patina’ develops under conditions of alternate wetting and drying to produce a protective barrier that impedes further access of oxygen, moisture, and pollutants, providing a unique aesthetic to the steel structure.
