During hot dip galvanising, the parts are immersed in a bath of molten zinc and as a result, the steel parts acquire a layer of zinc to protect them from corrosion.
The thickness of the zinc coating applied to the steel is quite thin at 70 – 100 µm (micrometres), but this is the most effective way to protect the steel from corrosion. Hot-dip galvanised products are generally used outdoors.
Good to know: Galvanizing is also favored by the fact that hot-dip galvanized parts do not require maintenance in a normal environment for about half a century, ~50 years.
The zinc layer also has the ability to ‘repair’ itself, i.e. up to 5mm of damage and scratches, zinc can be kept corrosion resistant by an electrochemical process.
For high-quality hot-dip galvanizing of small parts, including threaded parts, we use a separate line – centrifuge.
The line works on the centrifugal principle and the zinc coating is carried out at a temperature ~100° (550°C) higher than conventional zinc coating. This ensures high quality hot-dip galvanising of small parts, especially threaded parts, according to ISO 10684.
For the more demanding customer, we offer the DUPLEX coating system consisting of hot dip galvanizing and powder coating.
The powder coating line has been installed as an extension of the galvanising line, and thanks to this we can also powder coat newly hot-dip galvanised parts quickly, ensuring the best paint adhesion.
We have RAL and RR colours in our colour range. As a standard, we coat the surfaces of the parts to be painted with a layer of powder paint 70+/-5 microns thick.

Electrolytic zinc plating is a common method of coating steel. The surface coating achieved during processing ensures reasonable corrosion protection and a pleasant appearance at low costs. Thanks to the different passivations used, it is possible to achieve parts with different colour and corrosion resistance. Electrolytic zinc plating is also often used under paint to improve corrosion resistance and paint adhesion.

Nickel plating is used in the electronics and electrical industries. As a result of nickel plating, the surface of the plated part is shiny.
The main coated materials are steel and brass.
Electrolytic nickel plating options on a stand
Nickel plating is used in the electronics and electrical industries. The surface of the coated detail is glossy.
The main coated materials are steel and brass.
Electrolytic nickel plating options in the drum
In chrome plating, the part is covered with a nickel base coat. As a result, gloss and corrosion protection of the substrate is achieved. The nickel/chrome (Ni/Cr) surface is strong, good looking and gives reasonable protection to the substrate.

Electrolytic tin plating improves the corrosion resistance of the part, as well as its electrical conductivity, and adds machinability and solderability. Due to its low transfer resistance, it is mostly used in the electrical and electronics industries. Under the tin coating, a nickel layer (3-6µm) is used to prevent the substrate from mixing with the coating.

Passivation of stainless steel is a chemical process that removes oxide layers, welding residues and machining marks from the surface of the part. After treatment, the surface of the detail remains greyish and satin matt. Passivation increases corrosion resistance and homogenises the appearance of the part.
