Three ways to fix grating

Welded, clipped and bolted grating fixing — Welding, saddle clips and drilled fixing.

Welding – for floors that will never be removed, such as flooring around machines. Fillet weld at the first bearing bar of every corner, at least 20 mm long and 3 mm high; touch up the zinc after welding.
Saddle clips – a top plate, a hold-down that hooks under the beam flange and an M8 bolt. Quick to install, removable and no damage to the galvanising; suitable for all gratings.
Drilled fixing – a hole in the flange with clip plate, bolt and nut, where a hook-type clip cannot be used.

Rules for installation

Use at least four sets of saddle clips per panel – more on long spans, vibrating floors and heavy-duty panels.
Leave about 10 mm between panels and at walls; 15 mm or 5 mm edge gaps per detail.
Bearing bars always span between supports; check direction before fixing.
Use galvanised clips with galvanised grating and stainless clips with stainless grating.

常见问题

How many clips does a panel need?

At least four sets per panel, more for long spans, vibration or heavy loads.

Clips or welding?

Clips are removable and protect the zinc coating; welding is for permanent floors that will never be lifted.
