Can Corten Steel be used in water?

In summary, the outside rust layer protects it from further weathering, so it is essentially weather-resistant. Suitable for use in outdoor planters, log burners, and other accessories such as water features and fire bowls due to its weather-resistance

CORTEN steel is a weatherproof construction steel that continuously develops a barrier layer as part of the weathering process. Consequently, this layer prevents further corrosion and results in a characteristic patina in earthy and warm tones.

If you want a small pool in your garden but do not want to harden the ground, a weatherproof corten steel table is the best option. This table is easy to install, dismantle, and move. You can recycle it if you don't want it. It's low cost and low maintenance.
