Ceiling Tile Frames

Use these components to design your own frame to support ceiling tiles.

Steel frames are approved for use in UL fire-rated ceiling assemblies. Some also comply with ICC-ES standards for use in seismic-rated assemblies.

Aluminum frames are corrosion resistant and withstand higher humidity than steel.

Fiberglass-reinforced plastic frames are safe to use in food and dairy plants. Nonmagnetic, they’re also good to install in hospitals and labs that use MRI technology. These frames won’t conduct heat and electricity, unlike metal frames, reducing the risk of injury from electric hazards. All are approved for use in UL fire-rated ceiling assemblies. They also meet ICC-ES seismic standards. You can clean these frames with mild detergents—they won’t corrode.

Ceiling Tile Clips

Secure ceiling tiles or join ceiling tile frame components.

Clips for ceiling tiles keep ceiling tiles in place.

Clips for ceiling tile frames join ceiling tile frames and molding. Cross clips connect cross tees to main beams. For those with a 1” notch depth, use cross-lock clips to secure them in place. Both clips help you comply with ICC-ES seismic requirements when fastened with pop rivets. Use cross clips with a 1 9/32” notch depth to install lights or vents to beams where there isn’t a notch. Straight clips attach two main beams. When installed with pop rivets, these clips help you meet ICC-ES seismic standards. Tee clips join molding to main beams and cross tees.

PVC plastic clips must be used with fiberglass-reinforced plastic ceiling tile frames and molding.

Ceiling Tile Wall Molding

Secure tile frames to the wall.

Use fiberglass-reinforced plastic molding in food and dairy plants—paint free, it won’t blister or peel onto your product. Because it’s nonmagnetic, it’s also safe to install in hospitals and labs with MRI technology. Unlike metal molding, this molding won’t conduct heat and electricity, so it reduces the risk of injury from electric hazards. It complies with ICC-ES seismic standards when installed with pop rivets. It’s also approved for use in UL fire-rated ceiling assemblies. You can clean this molding with mild detergents and it won’t corrode.

Ceiling Tile Framing Covers

Covers Shown In Use

Tee Cover, Top and Bottom Shown

Instead of painting or replacing ceiling tile frames when they’re rusted and discolored, put these flexible PVC covers onto them for a clean appearance. They’re sized to fit most framing systems. If you’re using them with ceiling tiles with recessed edges, make sure the width of the covers will fit the recess.

Rated ASTM E84 Class A, their ability to limit the spread of flames and generation of smoke conforms to the highest classification. They also meet UL 94 V-0, which means they’ll self-extinguish within 10 seconds and won’t spread fire by dripping.

To cover your framing’s interior grid, you may need both standard and tee covers. Tee covers run perpendicular to standard covers to create a tee.

For a proper fit, choose covers for 1" wd. framing if your current 15/16" wd. framing already has a thick coating of paint.
