The story of RB73 is a story of passion for fire. But also of beautiful and timeless products. Handmade by professionals with love for the product. Enjoy beautiful moments, enjoy staying outside! Think of warm summer evenings, but also throughout the rest of the year there are often beautiful days when an outdoor fireplace can be used to give that wonderful extra warmth and atmosphere on your terrace.
The fires have glass fronted doors so you do not suffer from smoke, ash or sparks on the terrace.
The CorTen steel gives the fires a solid appearance and long life. The rusting process is different for each fireplace and therefore every fireplace is unique.
As the Scandinavians say, “No terrace without a fire ………… ..”
What does CorTen steel mean?
COR-rosion resistance : corrosion resistance
TEN-sile strength : tensile strength
It has been developed by US Steel with the aim of creating weatherproof steel. It is a metal alloy consisting of iron to which copper, silicon, nickel and chromium have been added.
CorTen steel properties
Characteristic of CorTenstaal is the brown-orange rust color and the long lifespan.
Through the addition of the other metals to the iron, CorTen steel develops a solid layer of rust, the oxide skin, which shields the deeper material from oxygen. In contrast to ordinary steel, corrosion is not a wear, but rather a protection of the steel.
The solid rust layer that has to develop will, depending on the weather, take 2 to 6 months. After this, the CorTen no longer delivers rust (water).
Faster start-up of the rust process
Accelerating and allowing to rust more evenly is possible with a salt or acid solution.
For salt, kitchen salt works fine and for acid can be thought of vinegar. Mix this with water in a plant spray and inject the product.
Benefits of CorTen steel
• beautiful appearance and gets a warm rust color
• very durable (lasts about 10 times longer than ordinary steel)
• very strong material (similar to stainless steel)
• does not need to be treated
• it is 100% recyclable
Disadvantages of CorTen steel
• rust water which is released at the beginning can give rust spots on eg tiles
• relatively expensive material
