Quality management

Rubb is a quality and engineering driven company. We have been certified to the ISO 9001 quality standard since 1997.


What makes Rubb buildings different?

Over the last 50 years, Rubb has grown into an international group of companies with complete engineering and production facilities in Norway, Great Britain, and the United States.

We service and support our products directly. This gives us total control over the manufacturing and service process and ensures that Rubb is accountable to the customer before and after the sale. The Rubb group of companies has become one of the largest and foremost manufacturers of fabric tension structures in the world.

  • Flange joints, cable elements, hardware and trim finishes properly sized and detailed
  • Structural trusses properly braced with horizontal purlins and frames at regular intervals to provide appropriate lateral bracing
