DUPLEX Stud Framing System

The Rondo DUPLEX Stud System provides an efficient method of creating internal door and window openings reducing the need to box studs and saving materials, time, and money.

Perfect for door openings and glazing in internal wall framing applications where typically the installation of a boxed stud configuration would be needed. Fewer products to install means much quicker installations, delivering all-important labour cost savings. 

It can also be used as a wall stud where the use of standard steel studs would require installation at closer centres. In this application, DUPLEX Stud provides additional load capacity and reduces not only the material cost but labour cost as well.

Partnered with new Fixing Brackets and existing medium gauge Slotted Deflection Head Track, the Rondo DUPLEX Stud System is the perfect addition to the Rondo family of
Wall Framing Systems.

System Components:

  • DUPLEX Stud
  • Wall Track
  • Slotted Deflection Head Track
  • Deflection Head Track
  • Noggings
  • Fixing Brackets


Key Features
  • Greater load capacity than standard flange wall systems negating the necessity for boxed or back to back configurations or the reducing of Stud centres
  • Integrated with the Rondo medium gauge Slotted Deflection Head Track providing better, positive connections
  • Like all Rondo Steel Studs, DUPLEX can be manufactured in custom lengths to suit the project
  • DUPLEX Studs are made from G2 grade steel for optimum cost efficiency
  • DUPLEX Studs are made from steel with a minimum gal coating of Z275
  • Higher walls can be achieved before noggings are required
  • Central rib on fixing flange allows for vertical alignment of wall linings
