Steel Grating
Galvanized Steel Grating
Galvanized steel grating is usually selected when carbon steel grating needs practical outdoor corrosion protection. The quotation should confirm base grating specification, fabrication details, galvanizing sequence, site exposure and packing protection.

Product overview
Galvanized Steel 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.
Galvanized Steel Grating specification path
| Base grating | Bearing bar size, spacing, cross bar pitch and support span should be confirmed before finish selection. |
|---|---|
| Fabrication before finish | Cutouts, banding, toe plates and welded details are normally completed before hot-dip galvanizing. |
| Galvanizing requirement | Outdoor exposure, coating expectation and relevant project standard should be stated if required. |
| Site exposure | Humid, coastal, chemical or drainage conditions should be discussed before production. |
| Packing protection | Bundle marks, pallet planning and surface protection help reduce handling damage during export. |
| Galvanized inspection | After galvanizing, buyers often check blocked openings, sharp zinc points, dimensions, labels and coating appearance. |
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 Galvanized Steel Grating model expressions
| HDG G325/30/100 | Hot-dip galvanized 32 x 5 mm bearing bar grating for outdoor access. |
|---|---|
| HDG G405/30/100 | Heavier galvanized grating reviewed for higher load or longer span. |
| Galvanized serrated panel | Serrated top surface plus hot-dip galvanized finish for wet areas. |
| Fabricated galvanized panel | Cutouts, banding and toe plates completed before galvanizing. |
Use these examples as RFQ shorthand, then confirm final dimensions, load, material, finish and drawings before production.

FAQ
Galvanized Steel Grating buyer questions
When is galvanized steel grating the right choice?
Choose hot-dip galvanized grating for outdoor platforms, drainage areas and industrial floors exposed to moisture. Dry indoor areas can often use painted grating instead.
Is grating galvanized before or after fabrication?
After. Cutting, banding, toe plates and welded details are completed first, then the finished panels are hot-dip galvanized so cut edges and welds are coated too.
Which galvanizing standard can be specified?
Hot-dip galvanizing can follow ISO 1461 or ASTM A123/A123M. State the required standard and coating expectation in your RFQ so the quotation follows your project wording.
What span can galvanized grating cover?
Span is chosen on the base grating. For Q235 /30/100 grating under a 4 kN/m² uniform load with 4 mm deflection, recommended maximum spans are G255 1260 mm, G325 1520 mm, G405 1790 mm, G505 2120 mm and G605 2430 mm.
What should be inspected after galvanizing?
Check dimensions, coating appearance, openings blocked by zinc, sharp zinc points, labels and bundle marks before packing. Zinc build-up can affect small openings and cut areas.
Can galvanized grating also be serrated?
Yes. Serrated bearing bars with a hot-dip galvanized finish are common for wet outdoor walkways and stairs. Serrations change the load rating, so confirm the span with serrated-bar data.
