KEY-LOCK® Suspended Ceiling System

Our KEY-LOCK^® Concealed Suspended 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, seismic and acoustic designs, it is strong enough to hold multiple layers of plasterboard.

The KEY-LOCK^® Ceiling System enables the mixing of primary Top Cross Rail and secondary components Furring Channel to increase spans, suspension fixing points and maximise structural design.

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

Our innovative Top Cross Rail and Furring Channel sections have rolled edges making them safer to handle and together with our state-of-the-art manufacturing processes, we can also produce these profiles in custom lengths or radiuses for vaulted and curved ceilings.

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. 

So, if you are after a ceiling system that stands the test of time and provides time saving and safety innovation features, you can’t go past our KEY-LOCK^® Ceiling System.

• Furring Channels and Top Cross Rails are available in radiuses for curved ceilings
• Furring Channels 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

• Flush plasterboard ceilings
• Suspended Ceilings for internal applications
• Fire Rated Ceiling System Applications
• Curved Ceiling Systems using pre-curved furring channel and top cross rail
• Raked and Cantilevered Ceilings
• Bulkheads as an architectural feature or concealing services
• Wall Framing for masonry walls - battening out irregular walls or providing a cavity for cables and plumbing
• Suspended Ceilings for External Applications
• Acoustic Ceiling Design available
• Seismic Ceiling Design available

Our KEY-LOCK^® Seismic Ceiling System uses Top Cross Rail and Furring Channel as the main grid components, along with accessories such as our new Heavy Duty Wall Track.

Depending on the room size and seismic loads, we will design either a perimeter fixing or plenum bracing option for your project.

Seismic forces are transferred to either perimeter restraints or plenum braces, which is achieved using our two new Seismic Joiners for Top Cross Rail and Furring Channel.

For large open areas, our KEY-LOCK^® Seismic Ceiling System is braced, with sliding connections to all perimeters. This allows seismic loads to be transferred from the ceiling and through the braces, to the supporting structure.

We've made life easy by developing Seismic Wizards that will design Rondo Seismic Ceiling Systems for you and it also provides you with a seismic design summary sheet that is easy to understand.

But of course, we also have a whole team of Technical Representatives and Engineers who can handle technical enquiries and provide seismic design advice for your project.

Advantages: 

• Complete wall and ceiling seismic system solution
• Strong enough to resist lateral forces during an earthquake
• Will limit the structural damage of the systems
• Accommodates differential movements resulting from inter-storey movements
• Prevent tiles and lining boards from dislodging and blocking evacuation paths
• Will support critical services after an earthquake
• Protects the safety of all building occupants

Since its initial introduction over 50 years ago, the Rondo KEY-LOCK^® Concealed Suspended 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.
