The Staff

Our professional staff ensures that production and installation of our constructions is in accordance with quality demands.

Our project leaders make sure that projects are realized within the set time frame.
With our own quality control system we can be certain that our work, e.g., our welding, also passes the scrutiny of third-party inspectors.

Our welders work under the guidance of our welding coordinators. Most of our welders have received IW training, and our welding coordinators are IWS graduates. Our coordinators supervise and support production, and conduct necessary performance tests.

Subcontractors

Our entire work process is conducted in accordance to the demands of the EN 1090 standard. Accordingly, all our subcontractor companies also adhere to the requirements of the standard.

We perform surface finishing of our products only via certified companies. Thus, we can guarantee that the corrosion protection and surface finishing of our constructions meet the strict quality demands of the certificate.
