Surface treatment

DI industrial company offers surface treatment for a wide range of materials and shapes. Significantly engaged are surface treatments - anodising of aluminium and its alloys, electroless nickel plating of steel, brass, copper and aluminium or its alloys, galvanic nickel plating and galvanic zinc plating, titanium oxidation, spray painting with water-based and solvent-based paints. Within these technologies we also provide further ones – shot blasting by sand, iron, corundum or glass beads, as well as elimination of Ni coating. Our main focus in surface treatments is quality and customer-oriented approach. The line capacity in connection with the professionalism of our staff enables us to meet the high demands of our customers, especially in terms of single and small batch production.

Surface treatment open hours:

Monday - Friday

6:30-11:30   /   12:30-13:30
