Types of corrosion protection
Protection against rust comprises two aspects: surface pre-treatment and the appliance of a protective coating that seals the surface. The pre-treatment technique, known as blasting, enhances the adhesion of the protective film. The protective film can consist of:
- one or more coating layers, the so-called ‘wet painting systems’
- a combination of a thin layer of metal coating, usually aluminium or zinc and a sealing topcoat. This process is called metallizing.
- an epoxy passive fire protection coating.
