Processes in the anti-corrosion protection plant (ACP):
- sandblasting
- painting
Sandblasting is carried out by steel shots. Granule size is in accordance with the client’s requirements, i.e. with the desired surface roughness.
We sandblast sheet metal of 4mm thickness and obtain 2nd and 3rd surface quality. Shot collecting and transport system is automated.
Sandblasting is manual. In the paint shop, we apply all protection systems.
