The Lietzke “BW” Series frames are conventional rebated pressed door frames. They are designed to suit the wall thickness, door type and door thickness. A pre-hung door unit in a “BW” Frame is either built into the wall during construction or retro-fitted using appropriate fixing methods. This allows all types of architectural door units to be ordered and delivered to site pre-hung in their frames with hardware fitted and finished in a factory controlled environment.
The door frames are fabricated by CNC punch press and CNC press brake with mitred and welded corners using Zincanneal or Galvabond steel. This provides a stronger rigid frame which is more aesthetically pleasing to other fabrication techniques. Depending upon the application, frames incorporate mortar guards, hinge plates with self-tapping screws for hinges, stud straps, buffers, wire ties, spreader bars and strike plates. Unless otherwise stated, “BW” Frames are 3-sided with a removable spreader bar fitted. The double rebate allows for either open in or open out door units. Where required, door seals and other accessories are fitted.
