KEY-LOCK® Direct Fix Ceiling System

If you need a more direct approach, Rondo supplies a wide range of direct fixing clips that allows you to direct fix Furring Channels or Ceiling Battens to either concrete, steel or timber ceiling structures.

Direct fixing clips need to be fixed along the sections in accordance with the relevant maximum span tables and each Furring Channel is required to be spaced as per the building board manufacturers' recommendations. 


  • Introduction to our KEY-LOCK® Ceiling System

    Our KEY-LOCK® Concealed Direct Fix Ceiling System is designed to produce a high-quality structure for a flush or featured finish to your plasterboard ceiling.

    Available for non fire-rated and fire-rated applications, bulkhead and acoustic designs, it is strong enough to hold multiple layers of plasterboard.

    The components within our Rondo ceiling system have been expertly designed to simply snap into sections, without the aid of mechanical tools. Offering an easy to install ceiling system, speeding up valuable time on site.

    Our KEY-LOCK® Ceiling System can be installed with our Acoustic Mounts to improve airborne sound and impact sound transmitted between floors particularly important in multi-residential projects. Additionally, our Technical Team can provide seismic design solutions using our KEY-LOCK® Ceiling System, which have been tested to meet Australian and New Zealand building codes. 

    • Ceiling Battens and Top Cross Rails can be ordered in special lengths
    • Able to be engineered designed for external ceiling use, e.g. Soffits
    • Base Material is engineered from G2 BlueScope Steel for strength and reliability
    • Rondo range of ceilings can interlock with each other in the same ceiling area, providing specialised ceilings after partitioning
    • Allows easy, economical and true bulkhead corner ceiling finishes to be achieved by using furring channel along with concealed support clips and fixings
  • Advantages of our Metal Ceiling Battens

    Using our metal Ceiling Battens in residential applications will cut back on the cost of call-back maintenance as they help control movement, reducing the chance of lining board cracks. We have a range of ceiling batten systems which are suitable for truss spacings from 600mm to 1200mm and for use in cyclonic and high wind areas.

    Our Ceiling Battens and accompanying clips have been load tested to ensure they meet all relevant standard requirements and can be purchased from our Rondo Partner Network.

    Two of our most popular clips are the 314 Direct Fixing Clip and the 390 Batten Swivel Clip.

    314 Direct Fixing Clip - to accommodate the increasing use of timber “I” beams, the 314 Clip has two extra nail or screw slots lower down on the clip, with an additional holding tab to assist installation.

    Cleverly, the temporary holding tab is tapped into the timber beam when the clip is at the right level freeing up both your hands to secure the clip.

    390 Batten Swivel Clip – with the ability to rotate 360°, the swivel clip can easily turn the ceiling batten on an angle that suits the change in roof truss direction. It also incorporates the temporary holding tab for quick and easy installation.

    Since its initial introduction over 50 years ago, the Rondo KEY-LOCK® Concealed Ceiling System has seen its use around the world in some remarkable projects from the Setia City Mall in Malaysia, to Australia’s largest tertiary institution, RMIT University in Melbourne.

    Specialised KEY-LOCK® Concealed Ceiling Systems have also been designed and produced, including those with a specific radius to create vaulted ceilings or curved ceilings, such as in the Pod Pavilion in Malaysia, the Aquatic Centre in Adelaide, as well as the famous "sky ceilings" at Venetian Casino in Macau.
