WHY CHOOSE CORTEN STEEL?
Corten steel is a popular choice for planters, raised beds, and outdoor furniture because it combines a distinctive rustic appearance with exceptional durability and minimal maintenance. Over time, the steel develops a natural protective patina that enhances its character while shielding the material from the elements, making it highly resistant to changing weather conditions.
DESIGNED FOR YEAR-ROUND OUTDOOR USE
At byJEMA, we create products designed to withstand outdoor use throughout the year. That is why we carefully select materials and finishes that can endure changing weather conditions while maintaining their appearance and quality for many years to come.
Our planters, raised beds, and outdoor furniture are crafted from corten steel, which develops a beautiful, living rust patina over time. The material combines outstanding durability with a warm, natural aesthetic that complements both modern and traditional outdoor spaces.
Corten steel – what you should know
If corten steel products are placed on tiles, concrete or wood, it can be beneficial to choose an area where staining will not be visible or where cleaning is easy.
It can be an advantage to place the corten steel planter box on e.g. weed cloth or painter's cloth or similar at the beginning of the process.
Make sure that water does not collect around the product as stagnant water can increase spillage. Choose with a bottom plate if necessary.
Use e.g. gravel, stone cement or another absorbent surface under the product to minimize visible rust marks.
If you want to reduce tarnishing quickly, the corten steel can be sprayed with a mixture of water and salt/water and vinegar to accelerate patination. Once the rust layer is stable, staining will decrease significantly.
Corten steel develops a natural patina
Corten steel is specifically developed for outdoor use and gradually forms a distinctive rust patina that protects the material from further corrosion.
When corten steel is new, the surface appears dark and relatively uniform. As the steel is exposed to wind, rain, and changing weather conditions, it gradually develops the warm rust-coloured finish that characterises the material.
During the first months of the weathering process, rain and moisture may wash loose rust particles from the surface. This is a natural part of the material's development and will gradually diminish as the protective patina stabilises.
Under normal outdoor conditions, corten steel will continue to develop its distinctive surface while maintaining its unique appearance for many years.
How to minimise the risk of staining
✅ Avoid placing new corten steel directly on light-coloured or porous surfaces.
✅ Ensure that rainwater from the product can drain away from paving, terraces, and building façades.
✅ Take extra care during the first few months while the protective patina is forming.
Over time, the surface stabilises and the risk of staining is significantly reduced.
No legal restrictions
Personal considerations when growing vegetables in corten steel
When using corten steel in the garden, including for growing vegetables and herbs, it is worth noting that there are no general legal restrictions on the use of corten steel for this purpose.
Corten steel is widely used in both private gardens and professional landscaping projects due to its long lifespan and distinctive appearance.
The decision to grow edible crops in corten steel planters is therefore largely a matter of personal preference and individual choices regarding garden design and aesthetics.
If you would like additional peace of mind, you can choose to line the inside of the planter with a geotextile fabric or a similar barrier between the soil and the steel.
This is not a requirement, but it is an option that some gardeners prefer for added reassurance.
Good drainage and nutrient-rich soil remain among the most important factors for healthy plants and successful growing conditions—regardless of the material used to construct the planter.
Ultimately, the choice is yours. Corten steel combines a warm, natural appearance with exceptional durability and minimal maintenance requirements.
For many gardeners and landscape designers, the choice of material comes down to aesthetics, growing needs, and personal preferences.
Corten steel – built to last
Corten steel is specifically engineered to withstand wind, rain, and changing seasons without the need for surface treatments or painting. As the material is exposed to the elements, it develops a natural rust patina that acts as a protective layer, helping to reduce the risk of further corrosion.
This distinctive patina gradually evolves over time, giving corten steel the warm, dynamic appearance for which it is renowned.
A simple cleaning when needed is typically all that is required to maintain the product's appearance and functionality for many years to come.
Black steel to a natural patina
When delivered, corten steel has a dark and relatively uniform appearance.
As the steel is exposed to rain, sunlight, and humidity, it gradually develops the distinctive rust patina that characterises the material. The patina continuously changes in colour and texture depending on the surrounding environment and climate, giving each product its own unique appearance. This process is completely natural and forms an essential part of corten steel’s durability, character, and long-lasting appeal.
A natural choice for modern gardens
Corten steel is a popular choice for planters, raised beds, and outdoor furniture alike. Its warm rust patina creates a natural contrast to the greenery of the garden, adding character and visual interest throughout the year.
The material combines a distinctive design aesthetic with exceptional durability and minimal maintenance requirements, making it well suited to both private gardens and professional outdoor spaces.
