Galvanising
Compared to other galvanic coatings, zinc coatings provide the best protective properties on iron and steel, both in terms of thickness and deposition costs. The protection level increases with galvanic coating thickness. Our galvanising station uses baths with excellent properties ensuring micro-smoothing of the zinc coating and with adequate flexibility for spring coating. After the required surface preparation, the shine of zinc coating is comparable to that of a chrome coating. Thanks to the high quality of our services, we keep on acquiring new customers in cities of the Silesian metropolis, such as Bytom, Tarnowskie Góry, Katowice, Chorzów, Piekary Śląskie, Gliwice, Zabrze. We currently coat small parts and elements up to 6 metres long.
Application:
- Protection of grey iron and steel against corrosion
- Protection of metal sheets, tapes, steel wires and small elements
- Protection of flexible elements
- Shine zinc coat application as a decorative coating
Tin-plating
Tin is a rare, soft metal which does not corrode in moisture-containing air. Tin applied in our acidic galvanic baths ensures silvery-white coatings with excellent soldering properties and conductivity. Our customers represent the widely understood electrotechnical sector, radio and teletechnical sector, as well as gastronomy. The use in gastronomy is caused by the rare fact – tin and its compounds are not toxic. Since our foundation, we have operated on the site of Elektrocarbon Sp. z o.o. – one of the main Polish manufacturers of graphite brushes. Our long-term cooperation resulted in development of excellent tin-plating methods of electric contacts and various copper, brass and steel elements. We currently coat small elements and elements up to 3 metres long.
Applications:
- Corrosion protection of copper wires
- Surface preparation to soldering
- Spring protection without deterioration of mechanical properties
- Protection of containers and devices for food production and storage
- Element protection against nitrification
- Regeneration of old electric contacts
Because of the softness of the metal, the coating is not decorative, and application on brass elements results in zinc diffusion into the coating and coating darkening. We managed to eliminate this disadvantage – we apply very thin nickel sub-coatings.
Phosphating
Phosphate coatings belong to the group of chemical conversion coatings – it is a coating obtained through transformation of external substrate metal layers (steel, grey iron) into a non-metallic form in a reaction with a phosphate bath. In addition to anti-corrosion properties, they are also used in other applications, depending on the bath type. We use:
Manganese phosphating
It decreases the wear of cooperating metal elements by forming a porous, black coating. It is characterised by high penetration rates, enabling significant oil quantities to be held in the coating pores. Thus, the phosphate layer prevents direct contact of metallic surfaces throughout the entire period of element cooperation, preventing sticking, adhesive wear and pitting.
Applications:
- Extending the lifetime of mobile machine elements
Zinc phosphating
It forms a graphite-coloured anti-corrosive layer. Protects steel or grey iron elements during long-term storage and transport. Thanks to its porosity, it is also used as a substrate improving adhesion of paint coatings.
Applications:
- Substrate under a paint coat
- Protection during storage

Nickel-plating
Galvanic nickel forms light silver coatings characterised by excellent substrate adhesion and hardness. Electrochemical nickel-plating is one of the most versatile surface finishing processes with many protective and technical applications. Our offer includes matte and glossy nickel. The best protection against corrosion is achieved by combining both coating types.
Applications:
- Protection against electrochemical corrosion, erosion and wear
Chromate treatment
Aluminium chromate treatment
Enables significant improvement of corrosion resistance of aluminium, however, this resistance always depends on the alloy used. Corrosion resistance of aluminium parts decreases with increasing levels of alloy additives, such as Cu, Fe, Si, Zn.
Copper, brass chromate treatment
Significantly improves corrosion resistance, and combined with appropriate etching, it provides micro-smoothing of treated details.
Thus, details subjected to chromate treatment achieve beautiful golden, glossy structure.
