Serrated Bar Grating Overview
Serrated bar grating uses notched top surfaces on the bearing bars, cross bars or both to provide additional traction compared with conventional smooth grating.
It is commonly considered where water, oil, process residue or outdoor exposure may create slippery walking conditions. Serrated surfaces are available across several bar grating constructions depending on the selected product series.
The final grating specification should still be selected according to bearing bar size, spacing, clear span, load and material—not surface style alone.
Serrated Bar Grating Construction Options
Serrated surfaces can be combined with different grating constructions according to material, load and project requirements.
Welded Serrated Bar Grating
Welded bearing and cross bars provide a rigid industrial grid with an optional serrated walking surface.
Press-Locked Serrated Bar Grating
Press-locked grating combines a mechanically locked grid with serrated surface options for industrial and architectural projects.
Swage-Locked Serrated Bar Grating
Aluminum swage-locked grating is available with serrated or grooved surfaces for lightweight access systems.
Riveted Serrated Bar Grating
Selected riveted constructions use serrated cross members or surfaces to provide additional traction under demanding service conditions.
Serrated Bar Grating Specifications
Serrated grating is selected by construction type, bearing bar size, spacing, surface, clear span and required load.
| Specification | Available Options | Selection Notes |
|---|---|---|
| Construction | Welded, press-locked, swage-locked, riveted where available | Select according to project requirement |
| Material | Carbon steel, galvanized steel, stainless steel, aluminum | Depends on construction and environment |
| Bearing Bar Height | According to load and span | Important for load capacity |
| Bearing Bar Thickness | According to grating series | Consider with height and spacing |
| Bearing Bar Spacing | According to selected series | Influences open area and walking surface |
| Cross Bar Spacing | According to construction | Defines transverse spacing |
| Surface | Serrated | Provides additional traction |
| Panel Size | Standard or custom | Confirm finished width and length |
| Bearing Bar Direction | Runs in span direction | Must align with supports |
| Clear Span | According to structural layout | Critical for load selection |
| Load Requirement | According to project design | Verify with appropriate load data |
| Edge Condition | Open or banded | Depends on installation |
| Finish | Mill, galvanized, painted or specified finish | Depends on material |
| Fabrication | Cutting, banding, notching and cut-outs | According to drawings |
One important point: do not automatically use the smooth-grating load data for serrated grating.

Serrated vs. Smooth Bar Grating
Both surfaces can use the same basic grating construction, but they suit different walking conditions.
| Comparison | Serrated Bar Grating | Smooth Bar Grating |
|---|---|---|
| Top Surface | Notched / serrated | Conventional smooth bar |
| Traction | Additional traction | Suitable for general conditions |
| Wet Areas | Often preferred | Depends on service conditions |
| Outdoor Use | Useful where surfaces become slippery | Common for general applications |
| Cleaning | Depends on process and debris | Simple open-grid surface |
| Load Selection | Check serrated load data | Use applicable smooth load data |
Choose Serrated Bar Grating where additional traction is needed because of moisture, oil or other slippery conditions.
Choose Smooth Bar Grating for general service conditions where additional serration is not required.
Case Study : Serrated Galvanized Grating for a Bulk Material Loading Area
This project required serrated galvanized grating panels for an outdoor loading area exposed to rain, dust and material spillage.
Project Requirement
A bulk-material handling contractor required open grating flooring around loading and transfer equipment.
The walking area was exposed to outdoor weather and occasional material residue, so additional surface traction was required.
Several panel dimensions and equipment openings were included in the layout.
Manufacturing Solution
Serrated galvanized steel bar grating was selected for the exposed service conditions.
Panels were fabricated according to the approved layout, with bearing-bar direction aligned to the supporting structure.
Required equipment openings and notches were produced before finishing, and cut edges were banded where specified.
Inspection & Packaging
Panel dimensions, serrated surface, bearing-bar direction, cut-outs and banding were checked before shipment.
Panels were marked according to installation area and packed in sequence for easier onsite handling.
Serrated Bar Grating FAQs
Serrated bar grating has notched top surfaces on bearing bars, cross bars or both to provide additional walking traction.
No. Serrated describes the surface. Welded, press-locked, swage-locked and selected riveted constructions can have serrated surfaces.
Serrated grating provides additional traction, while smooth grating uses a conventional flat bearing-bar surface.
It is commonly considered for wet, outdoor, oily or process areas where additional surface traction is useful.
Depending on the selected construction, carbon steel, galvanized steel, stainless steel and aluminum options may be available.
It can affect the effective bearing-bar section, so the correct load data for the selected serrated grating specification should be used.
Yes. Panels can be cut and fabricated according to project drawings.
Yes. Suitable serrated grating can be fabricated into stair treads with nosing and mounting details.
