Corten Square planter

These products are still available to ship

Corten steel planters have many benefits, both aesthetic and practical. They have an industrial feel but are not harsh or cold, and their beautiful coppery tones add depth and contrast to a scheme. They are increasingly popular in garden design, and being extremely durable and maintenance-free means they are  much in demand for commercial use as well. This low square shaped planter is ideal for large shrub and tree planting, and the 120cm square pot is the largest in our range.  Note that the proportions of the three sizes differ slightly.

Corten is a steel alloy designed to form a dense outer layer of rust which then seals the surface and prevents further corrosion. Any damage to the surface (scrapes and scratches) simply rusts over and self-heals. The pots start out steel silver in colour, and we speed up the weathering process by applying an aging treatment, so they are delivered with a protective layer of rust already formed.  This will continue to develop naturally over several months.

While the rust layer forms, paving or other flooring should be protected from rust-coloured run-off which may stain. The planters have small feet to make this more practical.  Corten planters do not require any ongoing maintenance, and are best left alone to develop their wonderful patina

Corten planters are made to order with a delivery time of about 6 weeks. If you select pre-weathering this will add a few extra days. Due to their size and weight they are dispatched on a pallet by our dedicated delivery service, together with any other items ordered.  Our pallet delivery charge is a flat rate of £40 for all orders to UK mainland destinations. For other destinations, please contact us for further information.
