HS - Herm Sprenger
SPRENGER only uses carefully selected high quality raw materials for the production to be able to offer a consistently excellent quality. Our suppliers are bound by contract to bring test certificates and material analyses for every new delivery that we receive. In addition we conduct our own quality controls. A deviation from the required quality is not accepted. Together with the controls being done after each production step we are able to guarantee that you receive a product in a class of its own.
