Duplex systems: double strength in corrosion protection
Duplex systems combine the corrosion protection of galvanising and powder coating, which leads to a significant increase in the duration of protection for metal and steel surfaces. Depending on the system, the corrosion protection extension factor is between 1.2 and 2.5. This combination offers comprehensive and long-lasting protection for your components.
With the duplex process, we combine the corrosion protection properties of galvanising and powder coating, which results in a significantly longer protection period. This is particularly invaluable for components that require optimum protection against the elements. We offer you both galvanising and powder coating of your components as a complete service from a single source.
Your advantages at a glance
Combination of galvanising and coating
The robust and maintenance-free galvanising prevents rusting under the coating. You are free to choose the colour of the coating, which enables decorative effects. The coating also protects the hot-dip galvanising from material erosion caused by the weather.
Extremely long-lasting protective effect:
Through the double corrosion protection, you can achieve a maximum protection duration for steel surfaces and metal parts.
References
Our references speak for themselves: you will find projects all over Germany, the Netherlands and other neighboring countries in which our galvanized components are used. From the north to the south, from major projects to smaller construction projects – surfaces need corrosion protection.

Your questions – Our answers
Why is the duplex system more effective than individual coatings?
The Duplex system combines the strengths of galvanizing and powder coating, resulting in optimum protection against corrosion. The galvanizing provides robust basic protection, while the powder coating adds additional protection against environmental influences and an aesthetic component. This combination significantly increases the durability and resistance of the coating.
What color options does the Duplex system offer?
The Duplex system offers a wide range of color options for powder coating. Customers can choose from a variety of RAL colors and special colors to achieve the desired aesthetic effect. This opens up numerous design possibilities for a wide range of applications.
Are duplex systems environmentally friendly?
Yes, duplex systems are environmentally friendly. Both the hot-dip galvanizing and the subsequent coating are carried out under controlled conditions in our company. This avoids work on construction sites that involves weather and temperature-related risks. The longer service life of the coating means that it needs to be recoated less frequently, which saves resources and reduces the environmental impact.
What is the production process for Duplex systems?
1. Surface preparation: Cleaning the component by blasting or pickling.
2. Hot-dip galvanizing: Dipping the component into a zinc bath for basic protection.
3. Cooling and inspection: checking the zinc layer quality.
4. Surface preparation before coating: Sweep blasting with non-metallic blasting media to clean and roughen the galvanized surface
5. Coating: Applying the powder coating
6. Curing: the coating in the oven.
7. Final inspection: Final quality check.
