A ceiling grid system hangs from the ceiling deck by hanger wire and provides a framework for ceiling tiles to set in place. These grid systems allow for room above the ceiling tiles, for access to duct work, plumbing, wiring, and for easy replacement.
Included in the grid system are main beams, wall moldings, cross tees, and hanger wires.
- Main beams carry the load of the grid system
- Wall moldings are used as a finishing trim to hang against the walls in the space
- Cross tees are the supporting grid pieces that attach perpendicular to the main beams, helping create the 24” x 24” or 24” x 48” opening needed for your tiles. Alternate cross tee sizes are also available for less common tile sizes.
- Hanger wires attach to the ceiling joists and are how the main beams and cross tees hang
ML and XL describe how main beams and cross tees attach to one another. The ML is a hook grid system and the XL is a stab grid system. The XL is required for seismic and specialty ceiling applications but is also the most common connection type across the United States.
The type of grid system needed is dependent on a few different things. First thing to consider is what size and type of tiles will be used within the space. Another thing to consider is the look you want. We have grid systems available in many styles and sizes. Additionally, you have unique circumstances to consider. We have grid systems for use in seismic areas, fire rated grids, as well as grids used for Clean Rooms. As always, reach out to one of our customer support experts or our installation services team for guidance on your specific circumstance.
Installing a ceiling grid requires planning and skilled work. We have many resources available to walk you through the process. Check out this

Yes, our ceiling grids can be cleaned. Our grid components are made from hot-dipped galvanized steel, with a corrosion-resistant zinc finish protecting it from rust. Refer to our
cleaning guide [PDF]
and
disinfecting guide [PDF]
for more info.
A 3” drop from the face of the grid is the minimum clearance needed for a drop/suspended ceiling. It’s not only a matter of getting the boards in, but the installers need room to twist the hanger wires, etc. Fiberglass is, of course, easiest to work with in the minimum clearance situation. More clearance can be given whenever possible to make the installation easier.
