Choosing steel grating sizes for drawings and orders
Steel grating sizes include more than panel width and length. Buyers also need bearing bar height, bar thickness, bearing bar spacing, cross bar pitch, edge banding and any cut-outs.
A size list works best when it follows the drawing. If the panels are for a platform or walkway, mark the bearing bar direction and support points before sending the inquiry.
Good fit for
- Panel size lists for procurement
- Standard walkway and platform panels
- Custom cut-to-size grating
- Replacement panels for existing frames
- Export orders with item marks
Confirm before quotation
- Panel width and length
- Bearing bar size
- Bearing bar spacing and cross bar pitch
- Banding, notching and cut-outs
- Drawing mark and quantity for each panel
Specification points buyers should check
| Panel direction | Width and length can be misunderstood unless the bearing bar direction is marked. |
|---|---|
| Opening | Spacing affects load, comfort and drainage. |
| Fabrication | Cut-outs and banding should be part of the size list, not added after price comparison. |
Common options to compare
- Cut-to-size gratingUse when panels follow custom dimensions.
- Spacing guideCompare 19W4, 15W4 and 30W4 patterns.
- Custom steel gratingPrepare drawings for special shapes.
- Steel grating productsChoose the product family before finalizing sizes.
How buyers use this guide
Use this guide to turn a broad inquiry into a specification the factory can quote. The decision usually comes down to panel direction, opening and fabrication. After that, compare Cut-to-size grating, Spacing guide and Custom steel grating so the product page, drawing and quote use the same assumptions.
A clear technical inquiry can be short: application, support span, expected load, panel size, material, finish, quantity and destination. If drawings are not final, mark the inquiry as budget pricing so rough dimensions are not treated as production sizes.
From inquiry to final order
At the first review stage, describe the working area, for example panel size lists for procurement. During technical review, confirm panel width and length, bearing bar size and bearing bar spacing and cross bar pitch. Before the order is released, freeze the drawing revision, finish requirement and packing marks so production and site installation follow the same information.
The details most often missed are bearing bar spacing and cross bar pitch, banding, notching and cut-outs and drawing mark and quantity for each panel. If those points are not confirmed, two suppliers may quote different scopes and the cheaper offer may not include the work the site actually needs. For project buyers, a clear scope is usually more useful than a bare square-meter price.
How to make the inquiry clearer
Send a panel schedule with width, length, bearing bar direction, spacing, material, finish and quantity. For replacement panels, measure the frame opening and support ledge.
Buyers may write this requirement as steel grating sizes, bar grating sizes, steel grating dimensions and metal grating sizes. Those terms should lead to the same practical checks: use, load, size, material, finish and installation.
For a practical quote, send drawings when available, or send the application, clear span, panel size, quantity, material, finish and destination.
