Zero Metalli deals with galvanic treatments on all metal surfaces, using versatile galvanic systems, specifically made in order to respond optimally to the different production needs, offering a complete service on the treatment of metal surfaces: a single supplier that guarantees the final results.
Chrome plating, nickel plating, tin plating, silver plating, copper plating, brass plating, bronzing, burnishing: the treatments can be carried out in the glossy, satin and opaque variants on iron and its alloys, copper and its alloys, zinc and its alloys, aluminum and its alloys, stainless steel. In addition to galvanic treatments, we offer cleaning-polishing processes also carried out by robots and painting-polishing processes.
Many processes can be carried out both in a static galvanic bath or rolling stock.

Treatments Performed
CHROMING
Chrome plating is the industrial process of coating a metal artifact with a layer of chromium, a steel-gray metal with a characteristic hardness and resistance to corrosion.
Chrome plating is undoubtedly, among all the most used in electroplating, the process that has undergone fewer variations since it entered industrial practice around 1920.
BRASS CHROMING
Copper alloys can be used in a variety of forms, which facilitates their use as foundry castings (finished or raw), or as hot or cold-worked products for forging, rolling, drawing, extrusion, drawing, etc. (sheets, plates, pipes, bars, wires) or finally as finished pieces, obtained with the processes of powder metallurgy.
Brass is a copper-zinc alloy.
SILVERING
Silvering is performed for both decorative and functional purposes, it is also applied in electrical engineering to facilitate electrical and thickness contacts for certain parts of motors. It should also be borne in mind that shiny silver has a high reflective power and this makes it suitable for optical applications.
NICKELING
Nickel plating is an electrolytic treatment that provides the processed materials with hardness, resistance to external agents and aesthetics.
Nikel plating process is carried out by converting the metal nickel of the anode into nickel ions which then pass into the nickel plating solution.
NICKELING
Electroless nickel-phosphorus plating is a chemical process that deposits an even layer of nickel-phosphorus alloy on the surface of a solid substrate, like metal or plastic. The process involves dipping the substrate in a water solution containing nickel salt and a phosphorus-containing reducing agent, usually a hypophosphite salt.
NICKELING AND TINING
Tin plating is an electrolytic galvanic treatment which covers a metal surface with certain layers of tin. These layers all have a different thickness and are deposited uniformly on the surface.
The main function of tin plating is related to protection by creating a sort of barrier useful for protecting the material to be coated.
COPPERING
In large industrial cycles, copper plating becomes indispensable for the protection of ferrous material. Although it does not provide a protective coating for its own sake, it is an excellent intermediate layer for the subsequent nickel plating, so that suitable copper-nickel-chromium deposits on iron are of high protective value and therefore recommendable.
ZINC PLATING
Zinc plating (also known as electro-galvanising) is a process where zinc is applied by using a current of electricity. While is does provide some rust protection, its thinner coating is not as rust resistant as hot dip galvanising. Its main advantage is it is cheaper and easier to weld.
ZINC-NICKEL PLATING
Zinc-nickel platings were developed as a result of increasing requirements with regard to corrosion protection, in particular from the automotive industry, against exposure to temperature, road salt and climatic conditions. Zinc-nickel platings are normally used if the traditional zinc-plating process is insufficient, due to high temperatures or aggressive environmental conditions. The Ni incorporation rates amount to approximately 10-15%. The ZnNi surfaces offer optimal cathodic corrosion protection and are highly resistant to thermal loads (up to 120 °C). This type of surface finish is usually used on steel, ferrous cast components and powdered metals. We offer the electrodeposition both as rack plating and as barrel plating.
Accessory Processing
SCREEN PRINTING
Screen printing is a technique of printing on any substrate or surface by the use of a fabric (printing fabric), by depositing ink on a substrate through the free areas of the fabric.
MECHANICAL CLEANING
Mechanical cleaning treatment goes from raw material (with roughness) to perfectly clean material (mirror), the necessary mechanical operations can be divided as follows:
- Grinding.
- Sanding.
- Brushing and polishing
Only after these processes it is possible to create excellent electrolytic coatings, especially in terms of corrosion protection.
THREADED INSERTS ASSEMBLY
Inserts are assembled with the following machines: CN press for self-hooking inserts assembly, pneumatic inserting machines, pneumatic screwdrivers for series assembly, projection welding of studs, column and traditional pantograph threading machines.
