The Quality System

The Quality System adopted at S.I.F.E.A., since its inception, has increasingly become an integral part of the life of the Company, being closely linked to the experience and professionalism developed in all these years.

The brilliant results have come thanks to a careful management of all the resources, economic and human, and the ability to solve the many market problems. All this is faced with the constant improvement of production by virtue of the investments that keep the company in line with technological development: it has been investing for years in the constant maintenance of the plants, but also in the training of technicians, and in compliance with the laws on safety and hygiene at work.

The certification of the Quality System is a further confirmation of the commitment made by S.I.F.E.A., and demonstration that the efforts and orientation to the quality of the Company have found full confirmation at the regulatory level.
