Colours and special solutions

The basis for product prices is always the black colour. Energy chains in any colour shown in the colour selection chart are subject to a percentage colour surcharge. Any other colours not shown in the chart are individually calculated depending on part and quantity, insofar as they are technically possible. For technical reasons, HT and ESD materials cannot be supplied in other colours.
