The main objectives of this research were:

- Analysis and solutions of press shop problems correlated with the forming behaviour of metallic coatings;
- Production-like laboratory investigations using special try-out tools and test equipment for analyzing and optimizing the tribological system: tool material - lubricant - coated sheet;
- Investigation and assessment of the coated sheets regarding the press shop performance under production conditions;
- Optimizing the forming conditions to solve specific problems caused by the coatings.

In the framework of the research programme the formability of different zinc coated sheets was compared to uncoated cold rolled steel. Under series production conditions, the press shop performance of the materials was investigated during the forming of the body panels wheel house and sun roof. The paintability and weldability of the coatings were also tested. ested.
