Duplex coating
The colour coating of hot-dip galvanized steel – also called Duplex system is a particularly high-quality protective system. Zinc and colouring complement one another’s effectiveness to increase the duration of corrosion protection by 1.2 to 2.5-fold. The colouring can be either be applied in the colour coating process or by powder coating.
The advantages
The advantages of a Duplex system with powder coating are:
- Very good long-term corrosion protection
- Suitability as a protection system for high-level corrosion exposure up to corrosion class C5
- Attractive appearance, unlimited colour variety
- High level of mechanical resilience
- Perfect all-round protection also of places that are covered and difficult to access as well as cavities
- High level of cost effectiveness due to its long service life
- Environmentally-sound process
- No drying needed, can be used straight away and transported immediately after coating
According to examinations by the Institute for Corrosion Protection in Dresden, a Duplex system, compared with an average colour coating with hot-dip galvanizing:
- is 10 times more abrasion resistant
- is 8 times more chip resistant
- offers 20 times more edge protection
