This cube planter arrives pre-weathered, so you get the real rusted finish from day one. Over time, the patina protects it from corrosion without paint, coatings, or ongoing maintenance.

Description

At 400 × 400 × 400mm, with a 64L capacity, it’s the right size for small feature trees, shrubs, or structured planting. The cube format makes layouts simple, use one as a feature or repeat them for tidy, consistent landscaping across a site.

The Corten Steel Planter is supplied with rubber feet to lift it off the ground, improve airflow, and reduce contact with concrete, pavers, or decking. A drainage hole is built in, so plants stay healthy and water doesn’t pool where it shouldn’t.

Note: While pre-weathered, some runoff can still occur as the patina continues to mature. Avoid placing directly on light coloured surfaces during this period.

Good product, correct tools make for easy assembly.

Its a good product. Use a small 10mm socket and long nose pliers to hold the allen key end of the bolt, better with 2 people assembling Make sure that the rolled edges face up, loosely assemble and then tighten. Takes about 10-15 minutes per box. Throw the shitty allen key and wrench that are provided away.

good product but nightmare to assemble

did not realize they were flat pack, thought how hard could it be once they arrived!, well I'm a pretty clever and handy person, but putting these together is a 2 person job, hopefully one with small fingers!! its messy as hell with rust/sand all through the packaging, the cap screws and nuts are a nightmare to assemble with and it took about 40 mins on my own and then I used my own tools not the suppled ones which would have added another 15-20 mins for sure. then went to assemble the 3d one a turns out they shipped a vertical planer not the long ones I ordered. I would ask for them to be assembled by them and shipped assembled next time.

Frequently Asked Questions

What is Corten steel, and why does it rust?

Corten steel is a durable weathering steel designed to form a stable, rusted patina over time. The rust layer protects the steel underneath, so it doesn’t corrode like ordinary steel. This makes it perfect for long-lasting outdoor planters

Does the planter come pre-rusted?

Yes. This planter arrives pre-weathered with a rich rusted finish. The patina continues to mature naturally outdoors, giving it a stronger protective layer over time.

Do I need to paint or treat the planter?

No. The steel’s natural patina protects it. No paint, coatings, or ongoing treatments are required.

How much soil does the planter hold?

The 400 × 400 × 400mm cube planter holds approximately 64 litres of soil, making it suitable for small feature trees, structured shrubs, or layered plantings.

Does the planter come with drainage holes?

Yes. It comes with a built-in drainage hole to prevent water pooling and keep plants healthy.

Are the feet included?

Yes, the planter is supplied with rubber feet. They lift the planter slightly off the ground, improve airflow, and reduce direct contact with hard surfaces like concrete, pavers, or decking.

Can I use this planter on decking or pavers?

Yes, but avoid placing it directly on light coloured surfaces while the patina is still maturing, as some rust runoff may occur and can stain decks and concrete pads.

Do I need to assemble it?

Yes assembly is required. The planter comes flat pack for easier transport and couriers. We recommend using gloves when assembling as the patina can rub off on your hands.
