The steel parts, which must be protected against corrosion, are dipped in a fluid zinc bath at a temperature of approx. 450° C (842° F) following a thorough cleaning of their surfaces. This process leads to a reaction between iron and zinc, thus producing an adhesive iron-zinc alloy coating. After removing the construction parts from the zinc-bath, they are coated with a pure zinc layer.

Hot galvanising is carried out in accordance with EN ISO 1461 or can be performed in accordance with any VZ standard requested by the customer.
The material to be galvanised must be free of oil, grease, paint and welding slag.
The parts must be constructed appropriately for galvanizing (see EN ISO 14713).

The size of our galvanisation tank allows us to work with parts up to the following dimensions:

Length: 10.8 m (35.4 ft)
Width: 1.2 m (3.9 ft)
Depth: 1.8 m (5.9 ft)

Even structural elements that exceed the dimensions of our zinc bath can be accommodated.

In the double-dip process, we can galvanise beams of nearly 18 m (59 ft) in length, frame structures about 3.2 m (10.5 ft) wide and unit lengths up to 10.8 m (35.4 ft) - special designs upon request.

The chemical composition of the steel to be galvanised also has a direct influence on the quality and appearance of the galvanisation.
