Quick answer
The Short Answer
Steel grating installs as a bolted assembly. Panels are laid so the bearing bars run across the supports, then fixed with clips, bolts or welding. Every order includes installation drawings and a fixing layout, so the assembly is clear before you start. This page works as a steel grating installation guide — the steps below are the method our drawings assume — and panels arrive flat, marked and ready to set in place.
Step-by-step
How Do You Install Steel Grating?
Installation is a bolted assembly — no field welding is required when you use clips. These six steps cover the standard sequence, and the fixing layout that ships with your order marks the exact points.
Lay out
Check the fixing layout that ships with the order and mark the support positions on the steelwork before lifting any panels.
Position
Set each panel so the bearing bars run across the supports and the panel sits flat on the support flange.
Align
Butt panels together and hold the small gap you need for thermal movement and drainage between panels.
Fix
Bolt clips or saddle fixings to the support flange at the marked points, near each panel end and at regular centers along the span.
Level
Walk the panels to check for rock or lipping, and shim the supports where the steelwork is slightly out of level.
Protect
Touch up any coating damage around the clips and keep the layout sheet with the maintenance log for future access.
Fixings advice
Which Fixings Should You Use to Hold Panels Down?
Most panels are held with grating clips or saddle fixings that bolt to the support flange, so panels can be lifted out for access without cutting. Where panels sit flush in a frame, countersunk bolts or spot welds are used instead. Clips and fixings are available as sourced companion items with your order, quoted with the same panels and documents in one line item.

Layout Tips That Save Time on Site
Plan the layout before anything is cut. Grating is cut to size at the factory, so the installation drawings and fixing layout that ship with the order already show panel numbers and support positions.
Mark before you lift
Work from the numbered layout sheet so each panel lands in the right opening the first time.
Keep bar direction consistent
Bearing bars should run the same way across a run so load, deflection and appearance stay uniform.
Respect the clear span
Never let a panel span beyond its rated clear span — extra supports are cheaper than over-engineering.

Choosing a Fixing Method
Four common ways to hold panels in place, and when each makes sense.
| Fixing method | Best for | Notes |
|---|---|---|
| Grating clips | Walkways and platforms | Removable, no field welding; clip and bolt per panel corner |
| Bolted plate / saddle | Heavy and vibration duty | Bolt through the bearing bar into the support flange |
| Spot welding | Permanent installations | Needs a welder on site; touch up coating afterwards |
| Countersunk bolts | Flush, smooth tops | Panel sits level inside the frame with no raised heads |

Frequently Asked Questions
What is the standard way to install steel grating?
Panels are positioned so the bearing bars run across the supports, then fixed with clips, bolts or welding to the supporting steel. Every order includes installation drawings and a fixing layout, so the bolted assembly is clear before you start. Panels are packed flat and stack easily on site.
What fixings do I need to hold grating panels down?
Most panels are held with grating clips or saddle fixings that bolt to the support flange, so no field welding is needed. Clips and fixings are available as sourced companion items with your order, quoted with the same panels and documents in one line item.
What are your sample and production timelines?
Samples ship in 5–7 working days and mass production runs 15–25 working days after drawing confirmation, both including hot-dip galvanizing. Quote within 24 hours.
