Speedline MF Ceiling System

The Speedline MF Ceiling System is a robust and fully certified metal frame solution designed to create a completely flat and seamless suspended ceiling, ready to receive a final decorative finish, such as plastering (skimming) or jointing. It is a preferred system in commercial offices, residential developments, healthcare, and education sectors across the UK due to its reliable performance and compliance with British and European standards.

The Speedline MF System version is used to:

• Conceal Services: Create a plenum void beneath the structural slab or roof, allowing all unsightly services (ducting, cables, pipework) to be hidden from view while remaining accessible.
• Enhance Performance: Deliver improved fire resistance and sound insulation (acoustic separation) between floors, achieved through the combination of the metal framework, the cavity depth, insulation, and the choice of plasterboard lining.
• Provide a Seamless Finish: Offer a higher-quality aesthetic than visible-grid tile ceilings, resulting in a smooth, monolithic surface suitable for high-specification areas.
• Flexibility: The depth of the void is entirely variable, and the system can accommodate complex design features like bulkheads and changes in ceiling height.

Key Speedline MF System Components

Speedline's MF components are typically manufactured from galvanised steel and are referenced using a straightforward numbering system similar to other major UK manufacturers.

• Primary Channel: SSMF7 - The main load-bearing channel. These run in one direction and are suspended from the structural soffit using hangers. They support the entire ceiling weight.
• Ceiling Channel / Furring Section: SSMF5 - Often referred to as a 'Top Hat' section due to its shape. These secondary sections run perpendicular to the SSMF7s and form the grid to which the plasterboard sheets are fixed.
• Perimeter Channel / Edge Trim: SSMF6A - An angle section fixed to the perimeter walls, providing support for the ends of the SSMF5 Ceiling Channels where they terminate at the wall.
• Rigid Angle Hanger: SSL06 - A rigid steel angle (e.g., 25×25 mm) used as a hanger to suspend the SSMF7 Primary Channels from the structure above, sometimes secured with an AMF12B Soffit Cleat.
• Connecting Clips: AMF9B - Pre-formed metal clips used to mechanically join the SSMF5 Ceiling Channels to the underside of the SSMF7 Primary Channels, creating the interconnected grid.
• Acoustic Hangers: AAH01B / AAH02B - Optional resilient components used instead of rigid hangers. These de-couple the metal framework from the structural soffit, significantly enhancing the airborne and impact sound insulation performance of the system.

Lining and Finishing

• Once the Speedline framework is erected, it is lined with standard plasterboard or specialist boards (like FireLine or SoundBloc, often from Siniat, British Gypsum, or Knauf) fixed using Drywall Screws at recommended centres (e.g., 230 mm in the field and 150 mm at the edges).
• The final surface is then completed using either taping and jointing to fill the seams or by applying a thin coat of plaster skim, giving the ceiling its final seamless appearance.
