About us
Qvatis GmbH is a technical industrial service provider founded in 2010, based in Sandstedt, Hagen im Bremischen (Lower Saxony). The company emerged in the context of nuclear facility construction and still works in this field today, particularly also in the decommissioning of nuclear power plants. Following the nuclear phase-out, Qvatis also established itself in the conventional industry, among other things in steel and metal construction, in plant engineering, and at port and logistics operations in the Cuxhaven, Bremen, Bremerhaven and Wesermarsch region. The range of services covers project and construction management, planning and design in plant engineering, calculations and strength verifications, welding technology, quality assurance and non-destructive testing (VT, PT), documentation, technical drawings, pre-inspection documentation, and feasibility studies. Reference projects include, among others, a nuclear wastewater filtration system, an ultrasonic system adapted for nuclear decommissioning, double-wall pipeline systems, steel platforms and staircase structures. In addition, Qvatis develops and markets its own product, the MAUU (Mobile Automobile Shelter), a modular steel structure with cladding made of aluminium/plastic composite panels, delivered as a kit.
