Screenshot-ready. Every dimension below is a standard tooling size — custom spacings are cut to your drawing at no extra mold cost.
| Type | Construction | Fixes to | Best for | Price index |
|---|---|---|---|---|
| A — G-clip | Upper saddle + lower J-hook + bolt | Flange of support steel (no drilling) | Standard walkways, fast install | 1.0× |
| B — saddle clip | Top saddle wraps cross bar + bolt to plate | Drilled/tapped support or plate | Heavy duty, removable panels | 1.2× |
| C — M-type weld-on | Welded anchor lug + bolt-down clamp | Welded to support steel | Permanent, vibration areas | 0.9× |
| Countersunk bolt | M8/M10 countersunk + nut strip | Through-panel to frame | Trench covers, flush surface | 0.7× |
Rule of thumb: A-type for speed, B-type for removability with heavy loads, C-type where vibration (crushers, compressors) loosens clamps.

Zinc thickness is measured per ASTM A123 (70–85 µm), salt-spray tested to 1,000 h. Stainless is pickled and passivated; FRP resin is matched to your chemical media.
| Material | Specification | Best For | QC Note |
|---|---|---|---|
| Carbon Steel, Hot-Dip Galvanized | Q235B / A36, zinc 70–85 µm per ASTM A123 | Walkways, platforms, trench covers, stair treads — the default choice | 1,000 h neutral salt-spray test before white rust |
| Stainless Steel 304 / 316L | AISI 304 (indoor / general chemical), 316L (marine / chloride) | Food processing, pharma, offshore, chemical plants | Passivated and pickled finish, 316L for >3% chloride media |
| Aluminum 6061-T6 | Mill or anodized finish, riveted or press-locked construction | Weight-critical platforms, water treatment, architectural meshes | ≈ 1/3 the weight of steel at comparable spans — cannot be hot-dip galvanized |
| FRP / Fiberglass (GRP) | Molded (isophthalic / vinyl ester) or pultruded profiles | Electrolytic areas, sewage plants, coastal platforms | Non-conductive, non-sparking, corrosion-free alternative to metal |
Per-m² clip quantity table (the number buyers always ask)
Values calculated to NAAMM MBG 531 with deflection limited to L/200. Need a stamped calculation sheet for your span? Ask in the quote form.
| Panel size | Clips per panel | Clips per m² | Bolt size | Typ. panel count per 1,000 clips |
|---|---|---|---|---|
| 1 × 1 m | 4 | 4.0 | M8 | 250 panels |
| 1 × 2 m | 6 | 3.0 | M8 | 167 panels |
| 1 × 3 m | 8 | 2.7 | M8 | 125 panels |
| 1 × 6 m (mill) | 12 | 2.0 | M10 | 83 panels |
| Stair tread | 2 per tread | — | M12 | 500 treads |
Wind uplift, pedestrian surge loads and vibrating plant call for +25–50% density at panel edges. Stainless clips for stainless panels; isolation kits ship with aluminum orders.
Clip quantity calculator
Enter your panel size and quantity — the quantity to order (including 10% spares, bagged by 50) and the matching bolt size appear instantly. Works offline on the printed page too: the formula is simply panels × per-panel count × 1.1.
| Panel size | Qty (panels) | Clips needed | Order (+10%, bags of 50) | Bolt size |
|---|---|---|---|---|
| 1 × 1 m | 100 | 400 | 9 bags (450) | M8 |
| 1 × 1 m | 500 | 2,000 | 44 bags (2,200) | M8 |
| 1 × 2 m | 100 | 600 | 14 bags (700) | M8 |
| 1 × 2 m | 500 | 3,000 | 66 bags (3,300) | M8 |
| 1 × 3 m | 200 | 1,600 | 36 bags (1,800) | M8 |
| Stair treads | 200 treads | 400 | 9 bags (450) | M12 |
Edge and vibration zones: add +25–50% at panel boundaries, crane beams and vibrating equipment. Send the panel layout and we return the full fixing schedule with the quote.
Where grating clips works hardest
Reference projects available per industry on request.
Clip-fixed walkways
A-type G-clips, 4/m² — panels removable for below-deck access.
Trench cover fixing
Countersunk bolts flush with traffic surface.
Removable access platforms
B-type saddles — lift any panel without tools beyond a wrench.
Plant floors on vibrating steel
C-type welded anchors — never loosen.
Stair tread fixing
Bolted carriers 2×M12 per tread; anti-loosening washers standard.
Aluminum panel fixing
SS clips + neoprene isolation to prevent galvanic pairs.

Clips are the cheapest line item on a grating order and the one that decides whether your floor squeaks, walks or comes apart. This page is written for the people who call asking “how many clips do I need?” — with the per-m² table, the matching bolts, and the three-installation-method explainer, plus a quantity calculator for your exact panel count.
The three installation methods, honestly compared
A — G-clips (saddle + J-hook). The default. The lower J-hook captures the support-beam flange, the upper saddle clamps the grating cross bar, one M8 bolt draws them together. No drilling, no welding, one wrench. Panel edge distance to supports must be ≤ 150 mm for the hook to reach.
B — saddle clips to drilled supports. For heavier removable panels: the saddle wraps a cross bar while the bolt threads into a tapped support or bolt-on plate. Handles higher uplift and stays aligned when panels are removed and replaced constantly.
C — weld-on anchors. Lug welded to the support, clamp bolted through the panel. Vibration-proof; used around crushers, shakers and engine rooms. Requires hot-work permits on site — order panels pre-matched to anchor layout.
How to calculate your clip quantity
Take the number of panels, apply the per-panel count from the table (4 for 1×1 m, 6 for 1×2 m, 8 for 1×3 m), add 10% spares, round up to the next 100 — clips ship in bags of 50. The calculator below does it: enter panel size and quantity, get bags to order plus the matching bolt size.
Two upgrades worth the money: stainless instead of galvanized in any wet or washdown area (the clip corrodes long before the panel), and nylon-insert lock nuts anywhere the public or maintenance staff will walk daily.
Material & corrosion matching
Galvanized clips on galvanized panels in dry service — fine. Wet or outdoor service: SS304 clips cost ~40% more and outlive three sets of galvanized ones. Stainless panels always get stainless clips; aluminum panels get stainless clips with neoprene isolation washers to break the galvanic pair. FRP panels in chemical areas get FRP or 316 clips — never bare galvanized steel in contact with chemical-washed FRP.
