Since 1994, Prefabricados Delta has applied a Quality Control System under the UNE-EN-180-9002 standard, Assurance Model for Quality manufacturing, Installation and after-sales services, in its main offices and in the Humanes and Puente Genil factories.
In December 1998, the company's Certificate of Incorporation was renewed in accordance with the requirements of UNE-EN-ISO-9001 Standard to cover design and manufacturing. Its scope was extended in August 2004 to include the manufacturing of Glass Reinforced Polyester pipes (GRP).
The Quality System implemented at Prefabricados Delta is certified by AENOR under no. ER-0221/1/94.
It is worth mentioning that the factories are audited four times a year, three of which are conducted by external auditors.
To achieve the aims set out in the Quality Policy of the company, a Quality System with specific guidelines has been developed, which are evident in a series of procedures geared towards ensuring that all employees carrying out work which may affect quality, have:
- Defined duties and responsibilities corresponding to their position.
- Necessary ability and training.
- Adequate information to carry out their duties.
- Corresponding resources and equipment to carry out their duties.
