Store Van fittings for Opel Vivaro commercial vehicles are GS certified and provide a high standard of rust resistance, thanks to the use of galvannealed sheet steel for the manufacture of the modules. This particular raw material, used in the automotive sector, is rendered strategically strong by cataphoretic coating, a technological treatment in which the sheet steel is dipped in an acrylic resin. Once dried, the acrylic resin is deposited on the surface of the treated element, forming a uniform protective layer that immunises it to attack by chemicals and the weather.
