SEW is a customer-oriented welding, construction, installation and E&I company. Our policy is aimed at a safe and environmentally responsible way of carrying out work on a project basis, including the agreed aftercare and with a good price-quality ratio.

HSEQ (Health, Safety, Environment and Quality), in Dutch KAM (Kwaliteit, Arbo & Milieu) is the basis of all our activities and also a part of Corporate Social Responsibility (CSR).

SEW therefore not only focuses on the internal organization but also looks beyond. We believe it is important to make a positive contribution to society.

We do this, for example, by:

Our processes and products are constantly tested against process indicators and product specifications. Where necessary, our products are tested for essential safety requirements and provided with a CE mark.


SEW attaches great value to good working conditions for its employees and is always focused on being able to perform work in a safe manner and in a safe environment. To enforce this policy, SEW has certified safety (SCC **) , & health management (OHSAS 18001, will soon be replaced by ISO 45001) systems.


Care for the environment is important for SEW. We of course all want to leave a beautiful world for our descendants. The environmental management system focuses on minimizing the environmental impact of our workshops and work on land locations. The environmental management system is based on the ISO 14001.


Delivering the quality desired by the customer is what SEW stands for and is fully committed to. This policy is being enforced by multiple certifications (ISO 9001, ISO 3834, PED Modules D & H, CPR / EN 1090-2) in the field of quality management systems.
