Duplex systems

DUPLEX SYSTEMS COMBINE THE CORROSION PROTECTION PROVIDED BY GALVANISATION AND POWDER COATING. THE EXTENSION FACTOR OF THE CORROSION PROTECTION FOR METAL AND STEEL SURFACES LIES BETWEEN 1.2 AND 2.5 DEPENDING ON THE SYSTEM.

Duplex systems: Double the protection for metal surfaces

Double protection is better - this applies in particular for our special duplex procedure for the protection duration of your metal parts or steel surfaces. Here we technologically combine the corrosion protection properties of galvanisation and powder coating. The result: This combination has a substantially longer effect than the respective individual solutions. This is invaluable, amongst other things for elements in facade construction, as these should be optimally protected against the weather.

With us, you will receive both the galvanisation and the coating of your components and steel surfaces from a single source.

Duplex systems – your advantages at a glance:

The robust and maintenance-free part galvanisation preserves the coating against underlying rust penetration. You can choose any colour for the coating process itself and thereby obtain a decorative effect. In addition, the coating protects the zinc against material abrasion through weathering.

Through the double corrosion protection, you can achieve a maximum protection duration for steel surfaces and metal parts.

Hot-dip galvanising is an extremely durable form of corrosion protection. According to the DIN EN ISO 14713-1, Table 2, a protection duration of more than 100 years can be achieved.

The zinc covering offers a reliable corrosion protection which is executed industrially and under defined conditions acc. DIN EN ISO 1461. Therefore, the requirements on the properties and reliability of hot-dip galvanising are clearly defined.

Hot-dip galvanising is maintenance free. Therefore, they are one of the least expensive long-term protection systems (because they protect longer and do not generate subsequent costs). It must be remembered that maintenance work in particular generates additional costs and can also cause problems, in particular in areas which are hard to reach. Maintenance free corrosion protection is therefore worth its weight in gold.
