Customer Specification
Quality Control
International Tests



Through our geology team we carefully select the quarries with the highest quality deposits to suit the individual and diverse needs of our clients.

All quarries are subjected to an initial investigation period to test and re-test the consistency of the material and colour. The tests are carried out regularly by the Laboratory of Material Engineering, China University of Geosciences, Beijing in China and also in independent laboratories in the UK. We have adopted the traditional European manufacturing methods. The managers and supervisors are of a high Western standard and the workers have been stringently trained in the importance of 'right quality for the right application'. Quality checks are carried out at all stages. Every crate is numbered to identify the responsibility of each operator and supervisor. A penalty and reward culture has been implemented from the beginning.

When quality counts accept no others.
