Suspension of Metal Ceilings

Suspended ceiling systems are supported from a primary suspension grid that is fixed directly to the structural soffit. From this primary suspension grid a suspension channel or profile is fitted, depending on the system type.

In lieu of using threaded rods that require adjustment time and brackets, an Emac primary grid system can be installed with speed and accuracy providing a rigid grid to suspend the ceiling system from.

Emac

Emac primary grid suspension components are designed by SAS International to reduce installation time and provide a superior finish to the installed ceiling.

All SAS International grid systems can be suspended from a structural soffit using a prepunched Emac Hanger. Each Emac suspension hanger has a pre-punched fixing flat that is suitable for most mechanical fixing to soffits. This avoids the need to snip, fold and punch angle or apply angle cleats.

Emac hangers used in conjunction with Emac channel or Emac hanger brackets provide infinite levelling, in steps of 0.50mm, without the need for drilling. Using self-tapping screws the primary grid system can be assembled using a hand screwdriver or cordless battery driver. Available in eight lengths from 400mm to 1600mm, suitable hanger lengths are readily available minimising wastage, see Emac Components for full range of sizes.

The Emac primary channel, used with the majority of SAS ceiling grids, is uniquely prepunched with an array of holes in a ‘V' formation at 100mm centres.

The Emac channel includes a central fixing hole to suit a system suspension bracket. By setting out a primary grid and utilising the ‘V' formation punching, runs of suspension channels can be fixed into the grid at building module intervals without the need for measurement.

The Emac channel is available in 4 metre lengths and in two gauges, 1.2mm and 1.5mm, both with an integral swaged coupler for in-line splicing.

Suspension Channels and Profiles

The suspension channel or profile is suspended from a primary grid using suspension brackets.

Depending on the system type ceiling tiles are clipped, hooked or laid into the suspension channel. Each system type utilises a unique suspension channel or profile.

Full details of each grid system are listed in the components section.
