  • DX Quality

    DX Quality "Made in Europe"

    For DONN® suspension grid production, Knauf AMF operates three production and logistics centres in Europe for the product brand DONN® and DONN® DX.
    In addition, the slitter plant in Antwerp, which is specialised in slitting thin steel and aluminium coils, complements the established DONN® competence and service system with the internal supply of raw materials – Quality “Made in Europe“.
    The continual development of the DONN® DX brand with its main innovations, namely the current grid standard, DX3® and the patented golden “Quick-Release™ cross tee clip”, form the core elements of the current quality and development standards
  • DX3® Technologie

    DX3® Technology

    The improved DX3® technology with the patented 3 rib design gives the main runners of the DX ceiling suspensions even greater rigidity. The main runners are more dimensionally stable and provide even greater torsional strength, making installation simpler and quicker. The result is a stable and secure ceiling grid structure.
    The locked end splice detail design of the main runners enables the profiles to be easily pushed together, even from a distance. The double ribbed end detail ensures increased strength of the connection point.The secure engagement and the resulting solid connection are confirmed with a clearly audible “click”, as with the patented and proven DX clip cross tees.
