Hot galvanisation + coating = DUPLEX
The combination of hot galvanisation in accordance with DIN EN ISO 1461 with suitable corrosion protection coatings is referred to as a duplex system. The coating offers not only colour design options but also many technical benefits.
Excellent corrosion protection properties with long protection duration can be achieved through coating systems as well as through hot galvanisation. The combination of both technologies produces a synergy: the resulting protection against corrosion is more durable than the sum of the single components. A protection duration of 25 to 50 years is possible.
