Does rusting steel require paint?
The theory behind using this is material is that as a layer of rust forms on the surface, this then offers the steel underneath protection from further deterioration thus this will eliminate the need for any paint to be applied. The reality of it is that for the steel to actually stabilise requires very specific environmental conditions which nature can fail to replicate.

Why is Corten Steel Protective?
The patina that develops on weathering steel has an inner and outer layer. The outer layer continually evolves and re-develops with new non-adherent rust products. The inner layer is comprised mostly of densely-packed fine particles.
Why is patina important for steel?
Corrosion Resistance. The most obvious and important benefit of weathering steel is corrosion resistance. The patina offers a protective coat against the elements and extends the lifecycle of the steel. Ultimately, this helps save on costs.
What is the patina on steel?
The patina, which creates a dark brown coating, is what protects the steel from any further corrosion from rain, snow, fog, ice, sleet and other weather conditions. Simply put, the steel is allowed to rust, and that rust creates a protective coating against the elements.
What gives corten steel its unique look and texture?
Eventually, the outer layer becomes less active and the inner layer starts becoming more prominent. This is what gives corten steel its unique look and texture. The outer layer weathers away, and the inner layer becomes even more densely packed.
Why is rusting steel smooth?
Because the rust products become so densely packed that water is no longer able to pass through to corrode the inner steel structure. Once it’s well-developed, the exterior layer on weathering steel should be smooth and feel as if it has a protective coating.
