Steel Grating Quotation Checklist: 12 Details to Send
By DONGFU GRATING Engineering Team · Published 2026-06-24 · Updated 2026-07-17
An accurate steel grating quotation needs twelve pieces of information: application, environment, load requirement, support span, panel size with span direction, material, surface treatment, surface type, quantity, installation method, drawings, and packaging or marking requirements. Application and environment select the material and finish; load and span fix the bearing bar size; panel sizes with the span direction marked prevent the classic — and dangerous — mistake of spanning the wrong direction; quantity in pieces, square meters or tons sets the price basis. Drawings, even sketches, remove ambiguity: they show cut-outs, banding, toe plates and clip positions that a parts list cannot express. Missing any of these forces assumptions, and assumptions become either inflated prices or wrong specifications. Buyers who send complete information typically receive a firm, engineered quotation within one working day instead of a week of clarification emails. This checklist explains what each item means, why the factory needs it, and the fastest format to send it in — use it before your next inquiry.
The 12 details that price your grating
| # | Detail | Why the factory needs it |
|---|---|---|
| 1 | Application (platform, walkway, treads, trench…) | Sets the product type and safety expectations |
| 2 | Environment (indoor / outdoor / wet / corrosive / marine) | Selects material and surface treatment |
| 3 | Load requirement (pedestrian / forklift / truck / uniform / wheel) | With span, fixes the bearing bar size |
| 4 | Support span (mm) | The single most important dimension — measured in the bearing bar direction |
| 5 | Panel size L × W (mm) + span direction | Wrong span direction is a safety failure, not a typo |
| 6 | Material (Q235 / Q355 / SS304 / SS316L / aluminum) | Drives strength, corrosion behavior and price |
| 7 | Surface treatment (HDG / painted / mill / anodized / passivated) | Corrosion protection and cost |
| 8 | Surface type (plain / serrated) | Slip resistance vs economy |
| 9 | Quantity (pcs / m² / tons) | Sets the price basis and production batch |
| 10 | Installation method (welding / clips / bolts / hinged) | Adds clips, holes or frames to the scope |
| 11 | Drawings (PDF / CAD / sketch) | Cut-outs, banding, toe plates, numbering — no ambiguity |
| 12 | Packaging & marking (pallets / steel frames / panel tags) | Export-safe packing matched to site sorting |
The span rule you must not break
Bearing bars carry the load; cross bars only tie the grid together. Panels must be supported on the two ends of the bearing bars. If a drawing mixes up length and width so the cross bars span between supports, the panel will fail. Always mark the span direction on panel lists and drawings.
Fastest way to send it
- Use the inquiry form: every field maps to one checklist item
- Attach or email drawings to info@dfwiremesh.com (PDF, DWG or clear photos of sketches)
- For large layouts, send the general arrangement — our CAD team details panels for you
What you get back
A specification proposal (bar size, spacing, surface, finish), panel schedule with numbering where drawings exist, itemized pricing, lead time and packing plan. Load capacity is confirmed against your span, load type and support conditions before the quotation is finalized.
Common Mistakes to Avoid
- Asking for a price per square meter with no span or load — any answer is a guess
- Mixing up length and width so the span direction is wrong
- Forgetting cut-outs and banding, then paying for site modification
- Leaving finish unspecified and comparing mill-finish prices against galvanized ones
- Not stating quantity units — pcs, m² and tons price differently
Quick Checklist
- Application stated
- Environment described
- Load requirement defined
- Support span measured (bearing bar direction)
- Panel sizes listed with span direction marked
- Material selected (or "unknown — advise me")
- Surface treatment selected
- Plain or serrated decided
- Quantity with units
- Installation method chosen
- Drawings attached or emailed
- Packaging / marking requirements noted
