Zincagem Martins has been operating since 1979, providing protective, electrolytic and non-electrolytic treatments, free from hexavalent chromium and heavy metals, which meet the corrosion resistance requirements of the main national and international automotive standards. In 2010, we opened our branch, with modern facilities and 100% automated zinc plating and phosphating lines, also located in Diadema, close to the Immigrant Highway and with easy access to the ring road.
