5. Corrosion protection

Corrosion protection by means of coatings:

The finished beam is given a factory coating of approximately 40 mm. Any other coatings, variant primer coats or top coatings which may be required must be agreed separately in the order. Standard colours are ndicated in the currently applicable price list.

In the standard design, the web is connected to the flanges with a continuous fillet weld. On the non-welded side of the web, in the neck region, an additional coating of zinc primer is applied. With the above corrosion protection, the product can be classified in Corrosion Protection Class I and II in accordance with DIN 55 928 Part 8.

To achieve Corrosion Protection Class III, further measures may be necessary on the non-welded side of the web-flange connection. These must be agreed separately with the factory.

Corrosion protection by hot galvanising:

The corrugated web beam can be hot-galvanised without difficulty.
