Galvannealed sheet steel, used in the production of Store Van commercial vehicle fittings, is the variant of hot-dip galvanised sheet steel which undergoes additional heating to a temperature of about 550°C. By means of this process, the zinc is bonded to the surface of the sheet steel, forming an alloy with the steel and a uniform galvanised layer. The sheet steel is then further toughened by cataphoretic coating, a treatment that releases a uniform deposit of an acrylic resin on to the component’s surface, to protect it from rust. This is why the quality and exceptional corrosion resistance of the mobile office modules for your Mercedes-Benz Citan van are so much better than the rest.
