Steel Grating
Heavy Duty Bar Grating
Heavy duty bar grating is reviewed when span, wheel load, forklift traffic, vehicle loading or maintenance equipment is beyond normal pedestrian access. Buyers should send load data, wheel contact, support span, frame details and drawings before quotation.

Heavy Duty Bar Grating specification path
| Load condition | Wheel load, forklift traffic, vehicle load or maintenance equipment should be clearly stated. |
|---|---|
| Bearing bar size | Deeper or thicker bearing bars are reviewed according to clear span and load. |
| Support condition | Frame, ledge, clear opening and bearing direction decide the practical panel layout. |
| Open area | Bar spacing balances load, drainage, cleaning and walking or rolling contact. |
| Finish | Hot-dip galvanized finish is common for outdoor or drainage heavy duty grating. |
| Accessories | Frames, anchors, lifting holes and removable panel marks can follow drawings. |
Standards reference
Standards and finish references can be reviewed by project requirement
- Steel grating can be reviewed according to drawings and standards such as YB/T 4001.1, ANSI/NAAMM MBG 531 or BS 4592 when required.
- Hot-dip galvanizing can be specified according to 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.

FAQ
Heavy Duty Bar Grating buyer questions
When do I need heavy duty grating?
When the grating carries vehicles, forklifts, trolleys or equipment, spans a long distance or covers high-load trenches. Normal pedestrian grating is not designed for wheel loads.
What load information do you need?
Traffic type, wheel or axle load, wheel contact area, clear span, support layout and any safety factor your engineer requires.
Which bearing bars are used for heavy duty grating?
Deeper or thicker bars such as 40 × 5, 50 × 5 or 60 × 5 mm, often at a closer bearing pitch for wheel contact. The final size follows the load and span check.
Can heavy duty grating be supplied with frames?
Yes. Angle frames, embedded frames, anchors and lifting holes can be made to your drawings.
Is a pedestrian load table enough for heavy duty grating?
No. Pedestrian tables cover uniform loads; wheel and point loads need a separate check using the actual load, contact area and span.
How are heavy panels handled for export?
Heavy panels are bundled with lifting points, panel marks and a loading plan so they can be unloaded and installed safely.

Quick span guide
Recommended maximum span by model (Q235, /30/100)

|---|---|---|
| G255/30/100 | 25 × 5 mm | 1260 mm |
| G325/30/100 | 32 × 5 mm | 1520 mm |
| G405/30/100 | 40 × 5 mm | 1790 mm |

Heavy duty grating reference
Heavy duty bar grating details for higher load conditions
Heavy duty grating quotation should start from load condition, clear span, bearing bar size, support method and whether wheel or point loads are involved.
RFQ parameters
| Load type | State pedestrian, equipment, trolley, forklift, vehicle or other loading condition. |
|---|---|
| Clear span | Support span is essential for selecting bearing bar depth and spacing. |
| Wheel or point load | Wheel size, contact area and axle load should be provided when applicable. |
| Support and fixing | Frames, bearing seats, clips or welded fixing should be clarified. |
| Finish and packing | Galvanizing, panel marks and heavy bundle handling should be planned early. |
Heavy access floors
Steel grating panels for stronger support and industrial service.
Drainage and trench use
Higher load covers may need heavier bearing bars and support frames.
Export handling
Heavy panels need clear lifting, bundling and loading plans.
