Due to the size of this item, it will be delivered on a pallet. A pallet delivery charge will therefore be applied at checkout.
Please note that only one pallet delivery charge will be applied per order. If you purchase multiple planters or other pallet-delivered items in the same order, you will still only pay one pallet delivery fee.
This circular rustic steel outdoor planter ring is designed to create a large and attractive surround around trees, shrubs or garden plants. The ring measures 900mm across and stands 600mm high. This is just under 3 feet wide and around 2 feet tall, making it a great size for creating a strong garden feature or raised planting area.
The tall circular design helps define planting spaces while giving plants plenty of room to grow. Many people use this type of planter ring around trees, flower beds or as a raised garden planter for flowers, shrubs or small ornamental trees.
The ring is supplied in two halves that bolt together. This makes it easy to install around existing trees or plants without disturbing the ground. Simply place the two sections around the tree or planting area and join them together using the bolts provided.
Because the circular outdoor planter does not have a base, it sits directly on soil, gravel or paving. This allows roots to grow naturally into the ground while still creating a neat and structured planting space.
What can this planter be used for?
This tall planter ring can be used in many different parts of the garden.
Many customers place it around the base of trees to create a raised border that can be filled with soil, bark or decorative stones. It can also be used to build raised planting areas for flowers, herbs or shrubs.
Some people use this size to create a feature planter in patios or landscaped areas. The large circular shape helps create a focal point while keeping planting areas tidy and well defined.
It works well in lawns, garden beds, patio spaces or larger landscaped areas.
What is it made from?
The planter ring is made from strong 2mm mild steel.
Each section is cut, shaped and drilled so the two halves can be joined together using bolts. This creates a strong circular ring that holds its shape outdoors in all weather conditions.
Every circular outdoor planter is designed and manufactured in the United Kingdom using British steel.
Why choose this planter ring?
Dimensions
Many of our products are made from what we call Rustic Steel. This is plain mild steel with no paint or coating. It is made to change when left outside. Over time, the steel reacts with air and rain. This creates a warm orange-brown finish, often called a patina. It gives the product a natural, aged look.
When your item arrives, it will look grey. It may also have small marks of light rust. This is normal. It is not a fault. It simply shows that the steel is beginning its natural ageing process. As the product stays outdoors, the rust layer will slowly grow and darken in colour.
How fast this happens depends on the weather. Rain, damp air and cold days will speed it up. Dry weather or a sheltered spot will slow it down. Each item will age in its own way. No two pieces will ever look exactly the same, which adds to their charm.
In normal outdoor conditions, full rusting can take a few weeks or even a few months. If you would like to speed up the process, there is a simple method you can try.
Mix equal parts distilled vinegar and hydrogen peroxide in a spray bottle. Add a quarter of a cup of table salt. Shake well. Spray the mixture evenly over the surface. This will start a fast reaction and you should see rust forming within a couple of days. Always wear gloves and eye protection when handling the mixture, and use it in a well-ventilated area.
Drag the slider to see how the steel changes over time.
If you are more used to working in inches and feet rather than millimetres, this quick guide can help. Below you will find a handy reference for some of our standard planter sizes, along with a simple converter to calculate more specific measurements whenever you need them.

No, our planters are not made from Corten steel. Corten is actually a specific brand name for a type of weathering steel. Over time the name has become widely used to describe any steel that develops a natural rust finish outdoors, much like how many people use the word “Hoover” to describe a vacuum cleaner.
Our planters are made from high-quality British steel that naturally weathers when exposed to the elements. As the steel sits outdoors, it slowly develops a rich rusted surface that protects the metal and creates the rustic appearance many people look for in garden planters.
This means you still get the same attractive weathered finish and long-lasting durability. The steel gradually forms a warm, natural rust patina that blends beautifully with plants, stone and timber in the garden.
Smaller planters are sent by courier. Larger planters or bulk orders may be delivered on a pallet to keep them safe during transport. Any products that require pallet delivery will be clearly marked on the product page.
No. You will only pay one shipping fee for your order, even if you purchase multiple planters. This makes it easier and more cost effective to buy several planters at once.
Yes, they can be placed on patios, decking or paving. During the early weathering stage, some rust runoff may occur. If you are placing the planter on light coloured surfaces, you may wish to raise it slightly or place it on gravel to reduce the chance of marking.
No special maintenance is required. The steel is designed to weather naturally outdoors. The rusted surface will continue to develop over time and does not need to be treated or painted.
Yes. Weathering steel planters are widely used in gardens and landscaping. Once the surface rust layer forms, the planter provides a stable and long-lasting container for a wide range of plants.
Yes. Steel planters are strong and designed for long-term outdoor use. As the rust layer develops it forms a stable surface that protects the steel underneath. This allows the planter to remain durable while maintaining its natural rustic appearance.
