Galvanized Serrated Grating specification path
| Serrated surface | Toothed bearing bars are reviewed for wet, oily, outdoor or traction-sensitive walking areas. |
|---|---|
| Galvanized finish | Hot-dip galvanizing is commonly used for outdoor corrosion protection after fabrication. |
| Bearing bar | Bar size and spacing still decide load capacity together with support span. |
| Walking condition | Slope, oil, water, mud or outdoor exposure should be described before final selection. |
| Fabrication | Cutouts, banding, toe plates and fixing details should be completed before galvanizing. |
| Inspection | Check serration, coating appearance, blocked openings, sharp zinc points and panel marks. |
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
Galvanized Serrated Grating buyer questions
When should galvanized serrated grating be used?
For wet, oily or outdoor platforms, walkways, stair treads and drainage access areas that need both grip and corrosion protection.
Does serration reduce the load capacity?
Yes. The serrations reduce the effective bearing-bar section, so check the span with serrated-bar data; a deeper bar may be needed.
Is the grating galvanized after fabrication?
Yes. Cutouts, banding and toe plates are completed first, then the panels are hot-dip galvanized so cut edges and welds are coated.
Is galvanized serrated grating suitable for stair treads?
Yes. It is often used for outdoor or wet industrial stair treads, usually with checker plate nosing.
What should be checked before shipment?
Serration, coating appearance, openings blocked by zinc, sharp zinc points, dimensions and panel marks.
Is serrated 19-W-4 grating available?
Yes. Serrated bearing bars can be supplied in the 19-W-4 pattern as well as metric patterns such as G325/30/100.
