Quality management is based on the principles established in the international norm ISO-9000:2005, which orients the Quality Management Systems of the companies of the group, in compliance with ISO-9001:2008 and the EU Construction Products Directive, which requires the CE marking for the majority of production materials employed by the Sando group.

Implementation of these systems gives Sando’s company structure a greater level of competitiveness in the market; international openings for strategic alliances; improvement to client service and confidence; reduction of administrative and operating expenses; more rational handling of human resources and maintenance of a flexible organisation that allows orderly growth and contracting.
