Cor-Ten – Available to order!

Cor-Ten, also known as weathering steel, is a popular metal for construction and landscaping. Cor-ten has established itself in the architecture and design world, with its distinctive colour and texture. The weathering process that brings this about occurs naturally when Cor-ten is exposed to a mixture of wet and dry conditions.

Once corroded, a concrete-like texture forms on the surface, providing protection against further corrosion and giving added grip. Cor-ten is a structural steel, it has a higher tensile strength to other everyday steel, making it useful for perforated flooring, fencing and public sculptural pieces. It is easy to form, perforate and weld.

Cor-Ten colour development

Initially, Cor-Ten has a yellowish appearance. The colour gradually changes as the protective rust layer develops from orange, to brown to a dark brown after one to two years. A rust accelerator can be used to speed up the process if a darker colour is desired sooner. The protective layer develops within a year under normal atmospheric conditions, as long as the steel surface regularly becomes wet and dry. In an industrial atmosphere the patina is formed more quickly and becomes darker in colour than in a rural atmosphere.
