Metallized coatings
Wet painting systems are often based on alkyd resin, epoxy or polyurethane paints. As an alternative to paint, it is also possible to protect steel with a thin layer of pure aluminium, zinc or an alloy of metals. This is called metallizing, also referred to as thermal spraying, metal spraying or flame spraying. Another commonly used term is Thermally Sprayed Aluminium (TSA).
