3mm Corten Steel Planters

The 3mm Corten Steel Planters from Metal Planters Ltd bring a distinctive natural warmth and texture to gardens, terraces, courtyards, and commercial outdoor spaces across the UK. Crafted from 3mm pre-weathered steel, each of these corten steel planters develops a rich, rust-coloured patina when exposed to the elements. This patina is not just decorative; it forms a protective oxide layer that guards the corten steel planters against further corrosion, giving them an exceptionally long working life.

Corten steel, also known as weathering steel, is prized in architectural and landscape design for its ability to age gracefully over time. The surface of these corten steel planters transitions through shades of orange, brown, and deep russet as the patina stabilises, creating an appearance that evolves with the seasons. This natural ageing process eliminates the need for painting, recoating, or surface treatment, making corten steel planters one of the lowest maintenance planter options available.

Every one of our corten steel planters is designed and fabricated by the Metal Planters in-house team at their Essex workshop. Smooth welded corners and clean, precise lines give each of our corten steel planters a modern, architectural appearance that complements both contemporary urban schemes and traditional garden settings with equal confidence.

These corten steel planters can be delivered fully assembled and ready to position, or supplied in component sections with a clear installation guide for easier handling on site. This is particularly useful for larger corten steel planters or installations on upper floors, rooftop terraces, and restricted-access locations where carrying fully assembled units would be impractical.

Optional drainage holes can be added to corten steel planters during manufacture to promote healthy root systems and prevent waterlogging.
