DiamondSteel© Ceiling Frame Systems revolutionise overhead construction with prefabricated steel frames that install 5 times faster than traditional methods. Our purple G550 steel frames arrive ready to erect, transforming weeks of on-site work into days. Backed by our 25-year warranty, it's the smart choice for modern construction.
Our prefabricated ceiling frames arrive as complete sections ready to erect, eliminating hours of on-site measuring, cutting and assembly. What traditionally takes weeks with stick-form methods, our teams complete in just days, dramatically reducing labour costs and project timelines.
DiamondSteel© ceiling frames provide exceptional fire resistance compared to traditional materials, maintaining structural integrity longer in extreme conditions. The non-combustible steel construction meets the strictest building codes for commercial and residential applications.
Every frame is manufactured in our quality-controlled facility using advanced CAD design and automated production processes. This ensures consistent straightness, exact dimensions, and perfect alignment that simply cannot be achieved with on-site assembly.
Pre-engineered pathways for electrical, HVAC, and data cabling eliminate coordination issues between trades. Our design team plans every service route in advance, preventing costly delays and ensuring clean, professional installations.
5 Times Faster Than Traditional Stick-Form Methods

Con-form Group has transformed ceiling construction across Australia with our innovative DiamondSteel© prefabricated frame systems. Unlike stick-form methods that require extensive on-site assembly, our frames arrive as complete, quality-controlled sections ready for immediate installation. Our in-house teams handle everything from initial design through to engineering certification and precision manufacturing. The result is a ceiling system that installs faster, performs better, and lasts longer than any traditional alternative.
