It is the surface that gives the base material its final functional and optical properties.

Surface protects.

The natural state of metals is an oxide. In the metalworks the oxide is extracted by using oxygen and energy and the pure metal is obtained. However, the metal is “predestined” to return to its original state at exposure to oxygen and water. And the less precious the metal is, the faster it happens. That is corrosion.

Surface technology slows down or prevents corrosion

Protection against corrosion through innovative surface technology increases service-life and thus raises the value of the product or structural component. Collini provides numerous possibilities to combat corrosion.

  • By means of electro-plating, structural components can be protected against corrosion with suitable metal coatings.
  • Powder coatings form impenetrable barriers against oxygen and water and thus protecting the underlying structure.
  • Hot-dip galvanising protects steel parts by specifically inducing the corrosion process on the zinc surface. And only there!
