Promack make bespoke Corten steel planters, often made from weathering steel, and are designed to age gracefully. Over time, they develop a warm, rust-coloured patina that is non-corrosive and enhances their aesthetic appeal.

This natural ageing process not only adds character but also provides a protective coating, eliminating the need for paint and maintenance. Ideal for both commercial and residential landscapes, these planters offer longevity with style.
