Steel Grating Bearing Bar Size and Spacing: RFQ Details Buyers Should Confirm
Steel grating bearing bar size and spacing should be confirmed before quotation because these details affect the grating specification, panel review and weight estimate. Buyers should send bearing bar height, bar thickness, bar spacing, cross bar pitch, panel size, support span, bearing direction, surface, finish, quantity, packing and drawings.
Why bearing bar details matter
The bearing bar carries the main load across the support span. A buyer may ask for "steel grating" or "bar grating" without stating the bearing bar size, but the supplier still needs the bar height, thickness and spacing before preparing a useful quotation.
Spacing wording can also vary by project. Some drawings show clear opening, some show center-to-center spacing, and some use specification codes such as 19-W-4. QY should review the drawing wording instead of guessing the spacing from a short RFQ note.
For product context, see steel bar grating, industrial platform grating and 19-W-4 steel grating RFQ details.
Specification details to confirm
| Detail | Why it matters | What buyers should send |
|---|---|---|
| Bearing bar height | Affects grating depth and review basis | Bar height or drawing specification |
| Bearing bar thickness | Affects weight and fabrication detail | Bar thickness or project wording |
| Bearing bar spacing | Defines opening and specification | Center-to-center spacing, clear opening or specification code |
| Cross bar pitch | Defines transverse bar spacing | Pitch value or drawing note |
| Bearing direction | Shows how panels sit on supports | Direction mark, support beams or span direction |
| Panel size | Defines cutting and banding | Width, length, panel marks and quantity |
| Surface | Affects walking surface request | Smooth or serrated surface |
| Finish | Affects quotation basis | Hot-dip galvanized, painted, untreated or stainless material request |
| Packing and drawings | Needed for export review | Bundle, pallet, marks, destination and drawings |
Key terms to clarify
- Bearing bar: The main load-carrying flat bar in steel grating.
- Bearing bar spacing: The repeated distance between bearing bars, often shown as center-to-center spacing.
- Cross bar pitch: The repeated distance between cross bars.
- Bearing direction: The direction in which bearing bars span between supports.
What to prepare before sending RFQ
For a faster steel grating review, prepare:
- Application area or product use.
- Bearing bar height and thickness.
- Bearing bar spacing or specification code.
- Cross bar pitch if specified.
- Bearing direction and support span.
- Panel width, length, marks and quantity.
- Smooth or serrated surface.
- Finish, edge banding and cutout notes.
- Packing, destination and drawings.
QY can review steel grating RFQ details for quotation, but should not claim load capacity, local compliance, slip performance, stock, price or delivery time without confirmed project data and drawings.

FAQ
What should a steel grating bearing bar spacing RFQ include?
Send bearing bar height, bar thickness, bearing bar spacing, cross bar pitch, panel size, bearing direction, support span, surface, finish, quantity, packing and drawings.
Is a 19-W-4 code enough for steel grating quotation?
No. A specification code helps, but buyers should still confirm bearing bar size, panel size, surface, finish, quantity, packing and drawings.
Why does bearing direction matter?
Bearing direction shows how the grating spans between supports. It helps review panel layout, support span, cutting direction and drawing marks.
Can QY confirm load capacity from bar spacing alone?
QY should not claim load capacity from bar spacing alone. Load review needs confirmed bar size, span, support condition, application and project data.
