Corten steel planter – bespoke – With base

High-quality manufacturing in corten steel, welded and assembled in our workshop near Angers.

Each planter is handmade with the utmost precision, we use thick steel with robust assemblies.

Our products are designed to last several generations. Our first priority is customer satisfaction.

Our Corten steel planters are fully welded, you will receive them as a single block.

Corten steel thickness: 2mm or 3mm (we adapt the thickness according to the size you order).

There is a rim on the top of the planter that is 37mm wide (modifiable on request).

To prevent your planter from being in direct contact with the ground, we add a designer support under the planter, and you can choose the height of the support.

The bottom of the planters is drilled to allow water to drain and ensure good drainage for your plants.

Corten steel is a modified steel to which phosphorus, copper, chromium and nickel are added.

This composition allows it to rust on the surface but never at its core.

It can therefore remain outdoors for several tens of years without ever deteriorating.

Its lifespan is approximately 5 times longer than that of ordinary steel.

Warning! : Your planter will not be delivered to you rusty (unless you have selected the “already rusty” option). You simply need to leave it outside for it to start rusting on its own.

The corrosion process of Corten steel extends over 2 years:

– From 1 to 3 months: Your planter becomes covered with a layer of superficial yellow/orange corrosion. Be careful with wooden and concrete terraces, during this phase rust streaks may stain your floor.

– From 3 to 6 months: The corrosion layer becomes darker and harder.

– From 6 months to 1 year: The colour becomes uniform, the rust layer becomes very solid. There are no more streaks.

– From 1 to 2 years: Your planter develops a patina until it obtains its final colour: brown more or less dark (each Corten sheet is unique, and so is its colour).

To fill your planter, we recommend proceeding as follows:

1) Place a layer of draining gravel approximately 5 to 10cm at the bottom of the planter.

2) Cover the gravel with a permeable geotextile

3) Cover with potting soil or topsoil

Your planter will be carefully wrapped on a pallet and once well protected, it will be entrusted to the Geodis carrier, who will deliver it to you by appointment.
