PATIN FORMATION PROCESS

Use nature

Initially, the steel begins to rust just like any other carbon steel when exposed to wet and dry weather conditions. However, over time, the layer of rust turns into a dense layer of patina, which covers the steel surface, resisting further corrosion. The color changes from fresh, newly developed orange-brown to light and finally dark brown.

The rate of change and the final color of the steel depend on the atmospheric conditions of the site and the quality of the surrounding air. A dense sulfur atmosphere will accelerate the oxidation process and lead to a darker coating. Frequent cycles of wet and dry weather conditions will also accelerate oxidation.
