Ceiling systems, particularly in commercial and high-end residential settings, offer not only aesthetic appeal but also functionality. Depending on their design and structure, ceiling systems can influence the acoustics, lighting, and air ventilation of a space.

One-way ceiling systems have increasingly gained traction in upscale establishments for their sleek and elegant design. What sets them apart is their absence of cross tees – the tiles are exclusively supported at the main rail’s ends. This minimalistic design offers an uncluttered look that architects and designers admire.

Common dimensions for one-way systems encompass 1200 x 1200, 1350 x 1350, and 1500 x 1500 measurements. Harcroft troffers, tailored for adaptability, accommodate the prevalent main rail heights of 45mm and 50mm.

The two-way ceiling system is the more traditional option, employing a Main Tee on either side of the fitting and two cross tees that adjoin to these Main Tees. These systems are versatile, with standard sizes like 300 x 600, 600 x 600, 300 x 1200, and 600 x 1200.

For these two-way systems, Harcroft troffers are crafted to fit the conventional main rail heights of 38mm and 45mm seamlessly.

Safety is paramount. Recognizing this, ceiling manufacturers insist on the deployment of safety hooks for optimum T-bar lighting support on the Main Tee. Even lightweight fittings demand these safety hooks, primarily because T-bars can roll due to grid movements. Harcroft, prioritising safety, equips their troffers with dual sets of safety hooks suitable for standard ceiling heights. Customised sizes are available upon request.

Warning! If lightweight metal luminaires are not supported on the top of the Main Tee in accordance with the installation requirements of the ceiling manufacturer, there is a risk of damage and injury to the building’s occupants.

Harcroft troffers come with two sets of safety hooks that can support the most commonly used ceiling heights. If you need a custom or different size please get in touch with us.

Particularly in earthquake-prone areas or when the luminaire weight surpasses the ceiling’s tolerance, additional restraints are a necessity. Harcroft’s troffers come designed with four restraint points on the fitting’s ends, ensuring balanced weight distribution and maximum support.

The vast array of T-bar troffer sizes, influenced by the luminaire’s design and the designer’s vision, can sometimes be overwhelming. Harcroft, with its expertise in ceiling systems, offers troffers tailored to diverse grid dimensions. They even provide custom-engineered solutions to cater to unique requirements.

Adhering to Australian standards, air return luminaires are crafted with side slots ensuring smooth airflow into the ceiling cavity, often merging with the building’s HVAC system. Harcroft’s luminaires come standard with black baffles, which mask any ceiling imperfections and protect the space from potential contaminants.

Air return fittings typically come with black baffles, which offer two distinct advantages:

Harcroft products are designed to include black baffles. However, some customers may choose to have the baffles removed to reduce costs.

Air-handling luminaires, featuring slots for air conditioning flow via air boots, negate the need for separate AC grills. Harcroft’s designs come with optional air boot support, including mounting brackets and guides, ensuring a snug fit for various AC manufacturers.

In conclusion, when contemplating ceiling systems, it’s crucial to consider not only aesthetics but also functionality and safety. With companies like Harcroft offering versatile, compliant, and safety-focused solutions, designing, and maintaining your ceilings has never been easier.
