Material and product decision guide
Welded Grating vs Riveted Grating
Riveted and welded gratings use different cross-member connections and may be offered for different duty ranges. Construction alone does not approve a traffic load.
For pedestrian, concentrated or vehicle service, require product data for the exact construction, bearing bars, span, support, wheel footprint and connection detail.
Side-by-side decision matrix
This matrix is a screening aid. It identifies what must be compared; it is not a substitute for the approved design or product data.
| Decision | Welded grating | Riveted grating |
|---|---|---|
| Connection | Cross bars are welded at intersections. | Cross members are mechanically riveted to bearing bars. |
| Product range | Regular and heavy-duty welded systems exist. | Availability and geometry are supplier-specific. |
| Traffic | Use the applicable regular or heavy-duty manual and product data. | Use verified heavy-duty or project-specific data where applicable. |
| Fabrication | Coordinate welds, cutouts, banding and finish repair. | Coordinate rivets, reticulated bars, edges and field alteration limits. |
| Inspection | Inspect welds, support, damage and restraint. | Inspect rivets, members, support, damage and restraint. |
Choose Welded grating when
- Welded construction is specified and supported by matching data.
- The fabricator can execute required cutouts and finish controls.
- The load case fits the selected regular or heavy-duty product.
All conditions still need confirmation against the exact panel, support, load case and governing specification.
Choose Riveted grating when
- Riveted construction is specifically required or accepted.
- Exact product geometry and performance records are available.
- Inspection and replacement arrangements suit the asset.
Ask the supplier to identify any qualification, exception or missing evidence before treating the option as equivalent.
Inputs required for a defensible comparison
A quotation cannot resolve the choice unless both suppliers receive the same technical basis. Include the following in the RFQ and record assumptions explicitly.
- Regular or heavy-duty product family
- Bearing-bar and cross-member construction
- Wheel or concentrated-load footprint
- Support, restraint and panel joints
- Fabrication, coating and inspection documents

What this guide does not decide
It does not approve structural capacity, slip resistance, fire performance, chemical compatibility, electrical suitability, accessibility or legal compliance. Those decisions depend on the installed system, jurisdiction, test method and order-specific evidence reviewed by the responsible project team.
