Zinc-nickel rack plating is one of the advanced coating methods used to provide long-term protection on metal surfaces that require high durability. Thanks to the nickel content in its coating structure, it offers much stronger corrosion resistance compared to standard zinc coatings. Applied through a rack system, this process ensures a controlled and balanced coating on the surface of the parts, delivering high surface quality especially for products with sensitive tolerances and complex geometries.
This coating system extends the service life of parts by providing strong protection against humidity, salt, temperature changes and aggressive outdoor conditions. With high adhesion performance, low porosity structure and passivation applications, long-lasting surface durability is achieved. In addition, different color and surface options can be offered to meet both technical and aesthetic expectations.
Zinc-nickel rack plating is widely preferred in automotive, defense industry, energy, hydraulic-pneumatic systems, fasteners and heavy industrial equipment. It stands out as an effective surface protection solution especially in applications where high corrosion resistance and process reliability are required.
