Steel Grating

Serrated bar grating uses notched bearing bars to improve traction in wet, oily, outdoor or washdown areas. Buyers should confirm bearing bar size, spacing, support span, surface finish and drawing details before quotation.

RFQ quick details





**Surface**Notched bearing bars improve traction in wet, oily, outdoor or washdown areas.



**Bearing direction**Confirm the bearing bar direction across supports and mark it clearly on drawings.



**Bar spacing**Bearing bar pitch and cross bar pitch should match load, drainage and walking requirements.



**Finish**



**Fabrication**Cutouts, banding, toe plates, fixing clips and panel marks can follow drawings.

 

For faster quotation, send panel size, bearing bar size, spacing, support span, finish, quantity and drawings if available.

Product overview

## How to Specify Serrated Bar Grating for RFQs

Serrated bar grating is usually selected for walking areas where moisture, oil, outdoor exposure or washdown conditions increase slip risk. For accurate quotation, buyers should define the panel size, bearing bar direction, support span, load requirement, spacing, finish and fabrication details.

QY Metal Tech can review drawings, cutouts, banding, fixing clips, stair tread use and export packing marks before production, so the supplied panels match the project layout and installation sequence.

 



### RFQ Specification Checklist

 

| Anti-slip surface | Confirm whether notched bearing bars are required for wet, oily, outdoor or washdown areas. |
|---|---|
| Bearing direction | Mark the bearing bar direction clearly so panels span correctly across the supports. |
| Load and span | Share support span, walking load, trolley load or other project load notes before bar selection. |
| Bar spacing | Confirm bearing bar pitch and cross bar pitch to match load, drainage and walking requirements. |
| Finish | Hot-dip galvanizing is common for outdoor carbon steel serrated grating. |
| Fabrication details | List cutouts, banding, toe plates, fixing clips, side plates and panel marks on drawings. |

 

 





Standards reference

## Standards and Finish References

- Steel grating specifications can follow project drawings, load requirements and recognized standards such as YB/T 4001.1, ANSI/NAAMM MBG 531 or BS 4592.
- Hot-dip galvanizing can follow ISO 1461 or ASTM A123/A123M when a defined zinc coating reference is needed.
- Platform, stair and access projects may refer to ISO 14122 or local safety requirements for walking surfaces and guardrail interfaces.
- Final specification should follow project drawings, load notes, local codes and buyer approval documents.

 



Specification examples

## Common Serrated Grating RFQ Models

 

| G325/30/100 | 32 x 5 mm serrated bearing bar for wet or oily walking areas. |
|---|---|
| G405/30/100 | 40 x 5 mm serrated bearing bar reviewed for longer span or heavier load. |
| HDG serrated | Serrated surface with hot-dip galvanized finish for outdoor platforms. |
| Serration direction | Bearing bar direction should be confirmed on drawings so the panel spans correctly across supports. |

Use these examples as RFQ shorthand, then confirm final dimensions, load, material, finish and drawings before production.

 

 

 

 



Applications

## Common Applications for Serrated Bar Grating

Serrated grating is commonly used where wet, oily or outdoor walking surfaces need better traction. These examples show typical project use cases and RFQ details buyers should confirm.







### Wet and Outdoor Access Areas

Used for outdoor stairs, washdown areas, wastewater plants, walkways and maintenance routes where traction matters.









### Cut-to-size Serrated Panels

Panels can be supplied by drawing with confirmed bearing direction, spacing, banding and finish.

FAQ

## Serrated Bar Grating buyer questions

 

When should I choose serrated instead of smooth grating?

Choose serrated bars where walking surfaces get wet, oily, icy or washed down, such as outdoor stairs, wastewater plants and maintenance routes. Smooth bars are easier to clean and suit dry indoor areas.



Does serration reduce the load capacity?

Yes. The notches reduce the effective bearing-bar section, so equal nominal bar depth does not mean equal capacity. Check load and deflection data for the exact serrated profile and span; a deeper bar may be needed.



Which serrated grating models are common?

G325/30/100 (32 × 5 mm bearing bars) is common for wet or oily walkways. G405/30/100 (40 × 5 mm) is reviewed for longer spans or heavier loads.



Can serrated grating be hot-dip galvanized?

Yes. Serrated carbon steel grating is normally hot-dip galvanized after fabrication for outdoor platforms, walkways and stairs.



Why must the bearing direction be marked on drawings?

Bearing bars must span across the supports. Marking the direction on each panel prevents panels being made or installed the wrong way round.



Can serrated grating be used for stair treads?

Yes. Serrated treads are often chosen for outdoor or wet stairs, usually with checker plate nosing and side plates made to your stair drawing.
