Garden bonfire corten steel CUBY

• Fill the soil all the way to the edge
• Ensure good drainage for watering
• Use natural fertilizer (e.g. raised bed soil or compost)

The steel is delivered with a small oil film and is therefore not rusted on delivery. We therefore recommend washing with lukewarm soapy water after installation to remove the oil film. Within a few weeks, depending on precipitation, the rusting process will begin. If you are impatient, the process can be accelerated by a wash followed by a salt water spray.

The final patination takes several years for the rust layer to develop and form a protective film on the surface. The color will go from completely orange to slightly darker over time.

A beautiful development.

Does corten steel spread rust on the underlying surface?

Corten steel has minimal corrosion resistance compared to regular steel. However, it will always leave a small amount on the surface at the beginning of the rusting process.

Therefore, when placed on tiles or wood, we recommend a base plate. There are holes for drainage in the base plate and the box will be raised approx. 5 mm from the surface to allow water to drain away. On concrete tiles, rust can easily be removed with oxalic acid.

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