is the best protection of products made from iron and its alloys against corrosion. Hot-dip galvanizing is the coating of steel with a zinc layer resistant to mechanical damage. During this process, steel products are submerged in a liquid zinc bath after they have been suitably prepared by degreasing, pickling and fluxing.
During galvanizing, an alloy of iron and zinc is formed at their interface, producing a durable coating resistant to environmental factors and mechanical damage. The ally of iron with zinc protects the product against corrosion even after it is damaged. Zinc coating is environmentally neutral, and it may be used under any conditions other than acidic and strongly alkaline.
„DUPLEX” – the best protection method
Duplex – state-of-the-art corrosion protection system used by our company. It is a combination of the anti-corrosive action of the zinc coating with the decorative values of paint coating. The period of effective corrosion protection provided by this system is on average twice as long as the combined lifecycles of the zinc coating and paint coating.

The guarantee period depends on the corrosivity of the environment in which the structure is to be stored, erected and used, as indicated in the table below:
|Corrosivity category and corrosion risk in accordance with PN-EN ISO 12944-2|
|Corrosion risk||Corrosivity category||Guarantee period|
|Very low corrosivity||C1||7 years|
|Low corrosivity||C2||7 years|
|Medium corrosivity||C3||6 years|
|High corrosivity||C4||4 years|
|Very high corrosivitye||C5-I||3 years|
|Very high corrosivity||C5-M||2 years|
