Grating clips install from above with a standard wrench. Set the panel on its supports, place a clip so it bridges the bearing bars and grips the support steel, and tighten the bolt until the clip sits snug. There is no welding, no drilling and no need to reach under the platform.

A grating clip clamps the grating to the steel it rests on. On a G-clip style clip such as U CLIPS, a top plate sits across the bearing bars, a toothed grip jaw hooks under the support flange, and one bolt pulls the two together.
Because nothing is welded, a panel can be lifted out for maintenance and put back with the same clips.
See the clip on the U CLIPS page.
Put at least 4 clips on every panel, one near each corner where the panel rests on its end supports, plus 1 at every intermediate support the panel crosses. A practiced two-person crew installs each clip in about a minute.
Total the clips for your platform with the calculator.
Clips grip the flange of the beam or angle the grating rests on, so the grating is held down without welding it to the beam. That keeps the galvanized coating on both parts intact.
Welding and weld lugs also work, but they need a welder, a hot-work permit and coating repair at every attachment point.
Grating clips vs welding vs weld lugs
| Clip | How it installs | Fits |
|---|---|---|
| U CLIPS (Universal Grating Clips) | From above with a standard wrench | 19-W-4 steel bar grating |
| R CLIPS (Odd-Spaced Grating Clips) | From above with a standard wrench | Odd-spaced bar grating, plus 19-W-4 and 15-W-4 steel grating |
| S CLIPS (Heavy-Duty Multi-Wing Clips) | Multi-point retention | All standard steel bar grating |
| A CLIPS (Self-Locking Bolt-On Clips) | Fast bolt-on | 19-W-4, 11-W-4 steel grating |
| N CLIPS (Saddle Clips) | Traditional saddle mount | All standard bar grating types |
| H CLIPS (Economy Grating Clips) | Simple hammer-on | 19-W-4 steel bar grating |
| C CLIPS (Flush-Mount Grating Clips) | Flush-mount below surface | 19-W-4, 15-W-4 steel grating |
| F CLIPS (Heavy-Duty Grating Clamps) | Clamps from above with a standard wrench | 19-W-4 steel bar grating |
| I CLIPS (Vibration-Resistant Grating Clamps) | Clamps from above with a standard wrench | 19-W-4 steel bar grating |
| M CLIPS (Fiberglass Grating Hold-Down Clips) | Bolted over two adjacent bars | Molded and pultruded (I-bar) fiberglass grating; steel bar grating |

No. FastGrate clips install from above with a standard wrench, with no welding, no drilling and no access needed below the platform.
At least 4 per panel, plus 1 at every intermediate support the panel crosses. The grating clip calculator totals it for a whole platform.
About one minute per clip once a two-person crew has the routine down.
Yes. Loosen the bolt, take off the clip and lift the panel. The same clips go back on when the panel is replaced.
Use M CLIPS. The M-shaped saddle straddles two adjacent bars and a bolt pulls the panel down to the support.
