Welding used to be the default way to secure steel bar grating. Modern grating clips changed that math: no hot-work permit, no coating damage, no cutting torch when a panel has to come up for maintenance. Here is how the two methods compare on the factors that matter to plant engineers and contractors.
| Factor | Grating Clips | Welding |
|---|---|---|
| Installation speed | Minutes per panel, from above with a standard wrench | Slow. Surface prep, a welder, and inspection at every attachment point |
| Hot-work permit | Not required | Required in most plants, adding scheduling delay and fire-watch cost |
| Removability | Panels lift out for maintenance and go back with the same clips | Grinding or torch cutting to remove; re-weld to reinstall |
| Corrosion | Galvanized/stainless clip preserves the grating's coating | Welding burns off the galvanized coating, so the weld zone rusts first |
| Vibration | Self-locking and multi-point clip designs resist loosening | Excellent: a rigid connection |
| Skilled labor | Any crew member can install | Certified welder required |
| Total installed cost | Lower in almost all maintenance scenarios | Higher once permits, labor, and coating repair are counted |
For removable panels, maintenance access, coated or stainless grating, and any site where hot-work permits slow you down, clips win. Welding still makes sense for permanent, high-vibration connections that will never need to come up. Those are the exception on most platforms.
Weld lugs are small steel tabs welded in place so the grating can be bolted down. The bolt makes the panel removable, but every lug is still hot work: a welder on site, a hot-work permit, and coating repair wherever the weld burns through the galvanizing.
Grating clips give the same removable connection with no welding at all.
Some systems drive a threaded stud into the support steel with a powder-actuated tool, then hold the grating down with a disc and nut. They also install from above with no hot work, but they need the actuated tool, a trained operator, and a stud driven into the structural steel.
Clips clamp onto the support flange without piercing it, using a standard wrench.
Request a QuoteOSHA 1910.22 requires every walking-working surface to support its maximum intended load and to be inspected and kept in safe condition. It does not name a fastening method. Clips specified to the grating manufacturer's installation detail meet that requirement and keep panels removable.
At least 4 clips per panel, one near each corner, plus 1 at every intermediate support the panel crosses. Use the grating clip calculator, or send us your panel sizes for an exact count.
Yes. FastGrate clips come in mechanically galvanized carbon steel, 304, and 316 stainless to match the grating and the environment.
