Frequently Asked Questions about Duplex

What is the Duplex Route?

Rotocoat offers the Duplex Route, a Duplex system of hot-dip galvanising and powder coating that complies with NEN 5254 and NEN-EN 15773. The Duplex Route provides the most enduring protection in the fight against steel corrosion. The powder coating protects the zinc layer from the outside and the zinc layer protects the steel against corrosion from the inside. This results in more durable protection than galvanising or powder coating separately. Duplex Route: 1 + 1 > 2

Rotocoat can provide the Duplex Route for every client and we make sure the material is processed perfectly, moving through the Duplex Route quickly and efficiently. In addition, the powder coating is available in virtually any colour so the result is not only durable but also stylish in appearance.
Rotocoat provides you with a total concept, with a single front desk, a single guarantee and a single invoice. In this way, Rotocoat can guarantee you high quality and reliable delivery times.

What is a Duplex system?

The combination of a paint system (organic coat) on a hot-dip galvanised substrate is known as a Duplex system. The thermal zinc coating provides excellent protection against corrosion for steel. A paint system (powder coating or liquid paint) also provides effective protection for steel from rust. The combination of the two systems results in extra long protection.
