Quality assurance systems

At ZEC SERVICE the appropriate quality of the execution of individual stages of each contract: production, repairs, and modernisation, has a decisive influence on safety and the precision of the industrial construction as well as the conditions for its operation. This means that the final quality of performed tasks in each investment is the sum of all factors connected to all of the essential aspects of the production process, i.e. material aspects, determined by the correct technological and technical usage of the appropriate amount of materials; personal aspects, determined by the possessed qualifications and certifications of employees; and company aspects, determined by the certifications possessed by the company, allowing it to perform specific tasks. These factors are included in the implemented quality assurance systems in accordance with both Polish and European norms and standards. This allows all implemented and performed procedures to ensure effective task performance, and to eliminate hazards connected to the performance of investment tasks on the side of the investor.
