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.
19-W-4 Steel Grating specification path
| Pattern | 19-W-4 welded grating has bearing bars at 1-3/16 inch (19/16 inch) centers and cross bars at 4 inch centers. |
|---|---|
| Bearing bar size | Bar height and thickness decide load capacity together with clear support span. |
| Support span | Span, bearing direction and load condition must be confirmed before bar selection. |
| Surface | Smooth or serrated bearing bars can be reviewed by walking condition. |
| Finish | Hot-dip galvanized, painted, mill finish or stainless option depends on project environment. |
| Fabrication | Cutouts, banding, toe plates, clips and panel marks should 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.

Steel grating technical references
Use these references with the applicable project assumptions. They support pre-quotation screening and are not a certificate or engineering approval. Final quotation follows the confirmed drawing, dimensions, load or service conditions. The original PDF language is retained; the 11-W-4 reference does not specify 19-W-4.
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.
