Steel Grating
Carbon Steel Bar Grating
Carbon steel bar grating is often selected for platforms, walkways, trench covers and general industrial floors before a final surface finish is chosen. The RFQ should confirm construction, bearing bar size, load, fabrication and whether the panel will be mill finish, painted or galvanized.

Product overview
Carbon Steel Bar Grating selection for project RFQs
QY Metal Tech supports international project buyers with drawing-based RFQ review, custom fabrication discussion, surface finish selection and export packing notes from Wuxi, Jiangsu, China.
Carbon Steel Bar Grating specification path
| Material | Carbon steel is used for economical strength when the finish is selected by environment. |
|---|---|
| Construction | Welded or press-locked construction can be reviewed by appearance and project requirement. |
| Bearing bar | Bar height, thickness and spacing are selected by span and load. |
| Surface finish | Mill finish, painted, powder coated or hot-dip galvanized finish can be discussed. |
| Fabrication | Cutouts, banding, notches, toe plates and panel marks should be completed before finish when required. |
| Packing | Panel bundles, marks and loading sequence help large projects install by area. |
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.
Specification examples
Common Carbon Steel Bar Grating model expressions
| Welded carbon steel grating | Economical carbon steel bar grating for platforms, trench covers and industrial floors. |
|---|---|
| Mill finish panel | Uncoated carbon steel option when later painting or indoor use is planned. |
| Painted panel | Primer or paint finish can be reviewed when hot-dip galvanizing is not required. |
| Fabricated carbon steel panel | Cutouts, banding and toe plates completed before final finish. |
Use these examples as RFQ shorthand, then confirm final dimensions, load, material, finish and drawings before production.
Applications
Carbon Steel Bar Grating applications and project references
These references help buyers connect carbon steel bar grating specifications with real site conditions, fabrication details, packing requirements and installation expectations.
Factory access floors
Carbon steel grating for platforms, catwalks and maintenance areas.
Trench and drain covers
Carbon steel grating can be reviewed for removable drainage covers.
Export packing
Panel marks and bundle sequence can follow the project drawing list.
Steel grating technical references
Use the load tables with their stated standard editions and design assumptions. The separate 11-W-4 specification describes a different bearing-bar spacing from 19-W-4 and is not an interchangeable load rating. Confirm the required specification and project loads with the quotation.
Technical checks before quotation
- Confirm bearing-bar center distance, cross-bar type and panel dimensions.
- Select the load-table row from clear span, support condition, load direction and deflection limit.
- Confirm material and finish, including galvanized, painted or stainless requirements.

FAQ
Carbon Steel Bar Grating buyer questions
What is carbon steel bar grating used for?
Industrial platforms, walkways, catwalks, trench and drain covers, and maintenance floors.
Which finishes are available for carbon steel grating?
Mill finish (black steel), primer or paint, powder coating and hot-dip galvanizing. Choose by environment: galvanizing outdoors, paint or mill finish for dry indoor areas or where painting is done on site.
Can untreated carbon steel grating be used outdoors?
It is not recommended. Uncoated steel rusts outdoors, so outdoor carbon steel grating is normally hot-dip galvanized or otherwise protected.
Welded or press-locked carbon steel grating: which one?
Welded grating is the economical choice for industrial floors and platforms. Press-locked grating gives a cleaner, more uniform grid where appearance matters.
Is fabrication done before the finish?
Yes. Cutouts, banding, notches and toe plates are completed first, then the panels are painted or galvanized.
Can I specify a steel grade?
Yes. Our span guide is based on Q235. If your project names another grade or material standard, state it in the RFQ so it can be reviewed.

Quick span guide
Recommended maximum span by model (Q235, /30/100)
Span at which a 4 kN/m² uniform load gives 4 mm deflection, calculated with the YB/T 4001.1—2019 Annex C method.
| Model | Bearing bar | Recommended max. span |
|---|---|---|
| G255/30/100 | 25 × 5 mm | 1260 mm |
| G325/30/100 | 32 × 5 mm | 1520 mm |
| G405/30/100 | 40 × 5 mm | 1790 mm |
| G505/30/100 | 50 × 5 mm | 2120 mm |
| G605/30/100 | 60 × 5 mm | 2430 mm |

Carbon steel bar grating details before finish selection
Carbon steel grating is often selected first by strength and geometry, then matched with galvanized, painted or untreated finish according to the project environment.
RFQ parameters
| Steel base | Confirm carbon steel material requirement if the project has a named standard. |
|---|---|
| Bar geometry | Bearing bar height, thickness, spacing and cross bar pitch define the grating type. |
| Fabrication | Cutouts, banding, toe plates and special panel sizes should be marked on drawings. |
| Finish decision | Hot-dip galvanizing, painting or black steel should be selected by site exposure. |
| Packing | Bundle marks and panel lists help installers identify panels. |
Carbon steel panels
Base steel grating panels for custom fabrication and finishing.
Galvanized after fabrication
Outdoor projects often finish carbon steel grating by hot-dip galvanizing.
Factory checks
Dimensions and fabrication details are reviewed before finish and packing.
