Products and services

Auxiliary services

  • Process outsourcing
- Electrolytic zinc coating consists of plating the steel (not stainless) with zinc to improve the primary material´s surface properties: wear resistance, increased hardness, corrosion resistance and improved appearance (colour, shine).
- Stripping consists of eliminating rust and metal particles from the surface of the primary material (iron or steel). There are various methods of stripping; in this case chemical stripping with acid dissolved in water, with other additives which may be inhibitors, humectants , surfactants or anti-foaming agents are applied.
- Degreasing can be a preliminary step prior to zinc coating or stripping when parts come pre-greased; it can also be a stand-alone process. It consists of removing oils and grease from the surface of the iron or stainless steel. It is carried out by immersion or by electrolytics.
