Handmade Corten steel
IRONeX Corten Steel is a class A steel, which is worked by hand and developed to offer unlimited solutions.
IRONeX surfaces undergo a controlled, accelerated oxidation treatment, followed by passivation. This process simulates four years of natural weathering, after which the surface features oxidation that gives every element unique shading.
IRONeX is also “made” from time, as the surface appearance will evolve as the years go by. The material’s physical expression creates a dialogue with different materials and contexts.
IRONeX is very easy to work with: it can be cut, moulded and modelled to suit the brief, thanks to our bespoke design service which follows the project from the concept through to installation. Each uniquely customised piece is the result of skilled craftsmanship, and is made to order, to suit any technical or creative brief.
The surface treatment is all hand-crafted with great attention to detail to enhance a material whose beauty will evolve over time.
The surface can be given LIGHT (pre-oxidised and passivated) or DARK (pre-oxidised, passivated and surface-treated with beeswax) finishes.

DARK FINISH:
pre-oxidised, passivated and waxed

LIGHT FINISH:
pre-oxidised and passivated
