This Corten Steel tree ring from Cortori adds a rustic, characterful accent to your garden. The round shape elegantly embraces the trunk, creating a neat, well-kept look around trees and shrubs. Made from 2 mm thick corten steel and designed to develop a warm, rust-brown patina - perfect for those who love natural materials with character.

Durable, Timeless and Low-Maintenance

Corten steel is resistant to all weather conditions. Thanks to its natural oxidation layer, the material is protected against corrosion while developing its unique, vibrant colour. This tree ring will remain beautiful season after season, without the need for extra care. An ideal choice for gardens where design and functionality meet.

Sleek and Functional Design

The tree ring consists of two half segments that can be easily placed around the trunk and securely fastened together. This allows for quick installation without damaging the tree. The design prevents grass or ground cover from growing right up against the trunk, ensuring a tidy and well-defined border.

Authentic Rust Colour Through a Natural Process

Upon delivery, the corten steel still has a grey metallic appearance. After exposure to moisture and open air, a rust layer forms, giving the steel its distinctive rust-brown shade. The first colour change occurs within two to four weeks. The rusting process can continue evolving for up to 18 months, depending on weather conditions.

Customer Questions

What is Corten steel?

Corten steel is a durable type of weathering steel that develops a protective rust layer. This layer gives the material its warm, natural appearance and also protects it against further corrosion. As a result, it is low-maintenance, strong, and ideal for use in gardens or architecture.

How long does it take for Corten steel products to develop a rusty colour?

Within a few weeks, the first rusty colour will appear, and after a few months the characteristic warm orange-brown shade will be fully developed. The exact speed depends on the weather conditions.

How can I make Corten steel rust faster?

Corten steel rusts naturally through exposure to the elements, but if you want to speed up the process, you can treat it with a mixture of water, salt and vinegar. Spray or brush this regularly onto the steel and allow it to dry outdoors. Repeat until the desired rust layer has formed. Make sure the steel can dry sufficiently between treatments, as it is the alternation of wet and dry that accelerates rust formation.

Is a Corten steel planter frost-resistant?

Yes, Corten steel is frost-resistant. The material withstands cold temperatures and does not crack or split due to frost.

Is Corten steel sustainable and recyclable?

Absolutely. Corten steel is a highly durable material and fully recyclable. Thanks to its protective rust layer, it will last for many years.
