We recommend washing with lukewarm soapy water after assembly to remove the oil film. Within a few weeks, depending on rainfall, the rusting process will begin. If you are impatient, the process can be accelerated by washing followed by a saltwater spray.

Corten steel is a unique material, it is a corrosion-resistant steel that develops a rustic surface when exposed to weather and wind. This surface protects the steel from further rust, making it an ideal material for outdoor use.

Corten steel also has the unique ability to change color over time, giving a rustic and natural look to your garden environment. This can create a beautiful contrast to the surroundings and create a unique expression in your garden.

Corten steel lasts up to 8 times longer than ordinary steel. The climate in which corten steel is used plays a significant role in its durability. Under optimal conditions, corten steel in gardens can last over 50 years, while a salty air will negatively affect its lifespan.

Does corten steel rust onto surfaces?

Corten steel only minimally rubs off compared to ordinary steel. However, it will always rub off a little on the surface at the beginning of the rusting process.

Therefore, we recommend using a base plate when placing it on tiles or wood. The base plate has drainage holes, and the box will be raised approximately 5 mm from the surface so that water can drain away. On concrete tiles, rust can be easily removed with oxalic acid.

Will the steel harm the plants?

You can grow and plant all kinds of vegetables and plants in this raised bed. Steel is a natural material and will not release toxic substances to your vegetables. If you're still in doubt, we recommend lining the box with plastic foil, a flamingo mat, insulation mat or similar. This will also insulate the soil from the sides of the box and extend its life.

Corten steel is generally not harmful to plants, as it is a corrosion-resistant material that does not release harmful chemicals or metals. However, it is important to examine the soil's pH value and add soil-improving materials if necessary, as corten steel may have a tendency to lower the soil's pH value. It is also important to ensure proper drainage in the plant boxes and raised beds, as corten steel can rust if it is persistently wet.

It is also recommended to regularly prune the plants and ensure proper ventilation in the planters and raised beds so that the plants are not suffocated by excess moisture. Overall, corten steel is a good choice for planters and raised beds.
