SAS 720

SAS 720 is a linear plank-style metal ceiling system. It features steel C-profile planks that hook onto a notched grid. The system is robust, demountable, and ideal for both interior and exterior applications. Its clean lines and durable finish make it suitable for commercial, education and transport environments.

This system uses a hook-on C-profile rather than a clip-in or lay-in method. Each profile securely hooks over a notched Emac grid, allowing full demountability while maintaining a flush appearance. It’s especially effective when used to conceal services or to create long, uninterrupted ceiling lines.

SAS 720 is available in three standard widths: 50mm, 100mm and 150mm. The standard depth is 30mm, and lengths go up to 3000mm. Profiles can also be customised to meet specific design needs. Waveform or other bespoke shapes can be created through SAS Plus, the in-house design service at Progressive Materials.

Yes. SAS 720 allows for service integration by forming apertures during manufacturing. These can be used for lighting, speakers, sensors or ventilation. Profiles are post-painted after cutting, ensuring a consistent, high-quality finish even around service openings.

It is. The system’s steel C-profiles and durable finishes make it suitable for both interior and exterior installations. For outdoor use, make sure to specify finishes that meet weather and environmental requirements.

The planks in this system are fully demountable. They can be lifted from the grid without special tools, offering straightforward access to the ceiling void. This makes ongoing maintenance or service installation much easier, especially in commercial fit-outs.

SAS 720 is made from rolled steel and comes in all standard finishes from Progressive Materials. Bespoke finishes are also available on request, including custom colours or textures to match interior branding or architectural themes.

The ceiling is suspended using Emac Hangers and a Notched Emac Grid. Splice details allow for long, continuous runs across spaces up to 1500mm between carriers, depending on the layout. The support structure ensures stability while allowing flexibility in spacing and layout.

The planks weigh approximately 0.9kg per linear metre, plus the weight of the suspension grid. The lightweight nature of the system makes it easier to install and suitable for both new builds and refurbishments.

SAS 720 is often specified for high-traffic commercial spaces, educational institutions, and transport hubs. Projects like the University of Aberdeen Library, Hamilton Square Station, and KPMG’s Leeds HQ all use this system. Designers favour it for its clean lines, ease of access, and service-friendly construction.

When installed with all system components, including the planks, carriers and brackets, SAS 720 offers a 25-year life expectancy. Its robust steel build and quality finishes ensure long-term performance with minimal maintenance.
