Corten Planters


Corten planters naturally develop a variable patina of bronze, rust and copper hues – colours which act as the perfect foil for all manner of planting schemes, both naturalistic and architectural.

All our corten manufacture is to-order and to your specification, and we do not hold in stock a standard range of shapes and sizes. 

Corten steel planters are extremely long lasting, and require no maintenance. Corten steel [aka ‘Weathering Steel’] contains alloys that cause its surface to develop a self-protecting rust when exposed to weather; and this protective surface layer will repair itself immediately if damaged mechanically (a characteristic which makes Corten planters particularly well suited for public realm).

It typically takes a few months for IOTA’s Corten planters to fully develop their characteristic and protective patina. Some run-off is to be expected during this time, and adjacent porous materials (such as porous stone or concrete) may need to be protected from staining. Once the patina is fully-matured, however, run-off will be negligible.

If run-off is a specific concern, and/or if the planters need to be installed with instant impact, then IOTA can pre-weather the Corten before shipment. This is a free-of-charge service, but it will add around 2 weeks to the delivery leadtime.
