Why black corten steel is treated with rust

Black corten steel will form a relatively independent layer of rust because of natural conditions, which will affect the use of a long time. We must rust it. In this way, not only the workability of black corten steel is improved, but also the service life is increased.

1. The rust red oxide film with stable color and uniform thickness, which is not easy to be rubbed off, is rapidly formed. Under the environment of 25 degrees Celsius outdoor temperature, the rust treatment process of black corten steel is usually completed within 3 hours.

2. Under the catalytic scheme of rust treatment of black corten steel, the surface roughness produced rapidly has a feel of hand, which makes the structure richer in volume and quality, sublimates the visual and sensory effects, rapidly improves the effect of landscape design, and enhances the economic and artistic benefits.

3. The rust treatment of black corten steel is not affected by local geographical location, local weather, location and so on. The rust red oxide film formed is uniform and stable in color.

4. The rust treatment process of black corten steel is non-corrosive and will not affect the formation of rust layer on the later surface. It is environmentally friendly, non-toxic and harmless.
