I. Understanding the Weathering Process


Corten steel has a unique ability to weather naturally when exposed to air and moisture. Over time, a special substance - a protective layer of rust - forms on the surface, which acts as a strong armour for corten steel, effectively preventing further corrosion of the underlying metal.

In order for this layer to form evenly and perfectly, adequate air circulation is essential. When placing large outdoor planters, it is important to avoid burying them completely in the soil or placing them in a permanently humid environment, as this will prevent the rust layer from forming properly.

In addition, in the early stages of weathering, Corten steel may produce rust-coloured, watery runoff that can easily leave stains once it comes into contact with nearby stone, paving materials or concrete surfaces. Therefore, pre-weathering the steel off site can significantly reduce this occurrence. At the same time, a properly planned drainage system or a gravel bed between the edge of the flower pot stand outdoor and the hard surface can also be effective in preventing staining of adjacent surfaces.
