How Many Grating Clips Do I Need?

Plan on at least 4 clips per grating panel, plus 1 clip at every intermediate support the panel crosses. Use the calculator below to total it for your platform, then send the number straight to a quote.

The rule of thumb

  1. Every panel gets at least 4 clips, one near each corner where the panel sits on its end supports.
  2. Add 1 more clip at every intermediate support the panel spans across.
  3. Clips per panel = 4 + intermediate supports crossed. Total clips = clips per panel x number of panels.
  4. Add a few spares for cut panels, openings and field changes.

Worked example

A mezzanine uses 12 grating panels, and each panel spans across 1 intermediate beam. Each panel needs 4 + 1 = 5 clips, so the platform needs 12 x 5 = 60 clips. With 5% spares, order 63.

The 4-per-panel minimum comes from grating manufacturers' installation details. OSHA 1910.22 sets performance requirements for walking-working surfaces rather than a clip count, so the engineer of record or your grating manufacturer's detail governs the final number.

Frequently Asked Questions

How many clips do I need per grating panel?

At least 4 per panel, plus 1 at every intermediate support the panel crosses. A panel resting on two end supports with one beam in the middle needs 5.

Does OSHA say how many grating clips to use?

No. OSHA 1910.22 sets performance requirements for walking-working surfaces, not a clip count. The 4-per-panel minimum comes from grating manufacturers' installation details, and the engineer of record has the final say.

Should I order spare clips?

A few spares cover cut panels, openings and field changes. The calculator can add 5% or 10% to the total.

How long does installation take?

About one minute per clip once a two-person crew has the routine down. The calculator shows an estimate for your clip count.

Which clip should I use for my grating?

It depends on the grating type and bar spacing. See the grating clip selection chart, or send us your grating details and we will match the clip.
