Running gears from BPW offer robust technology for a long vehicle service life. An important quality feature of our products is cataphoretic dip-coating with zinc-phosphating (KTLZn), a special surface finish that provides 5 times more effective corrosion protection than the conventional painting processes. From axle to the complete suspension with frame, all products from BPW receive a series KTL-coating.
Optimum finish from the very start
During the cataphoretic dip-coating, the KTL-coating pigments (positive charge) deposit on the electrically conducting components (negative charge) with a uniform thickness. Subsequently this layer is burnt in.
