Key-Lock Concealed Ceiling System

The Rondo KEY-LOCK Concealed Ceiling System we supply is designed to produce a high-quality structure for a flush or featured finish to your plasterboard ceiling.

You can direct-fix or fully suspend your KEY-LOCK ceiling.

When you require a suspension depth of more than 200mm, a fully suspended KEY-LOCK ceiling system is the way to go. Its the most popular and superior ceiling system as it is available for fire-rated, bulkhead, seismic and acoustic designs, as well as having the strength to hold multiple layers of plasterboard.

The components within the system have been specially designed so that they simply snap into sections, without mechanical tools being required. This offers Contractors an easy to install ceiling system and speeds up time on site.

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

Rondo KEY-LOCK Ceiling System can also be installed with our Acoustic Mounts to improve airborne sound and impact sound transmitted between floors, which is particularly important in multi-residential projects.


Primary and secondary profiles available in custom lengths or radius.
Able to be engineered designed for external use, e.g. Soffits.
Base Material 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
