ADA requirements
What ADA Grating Requirements Ask
ADA grating requirements are about the walking surface: accessible routes must stay free of openings that can trap a cane, heel or wheelchair caster. We translate that into a geometry we produce to — honestly and on the record. An ADA-compliant pedestrian grating panel is specified by its opening envelope and cross-bar spacing, not by surface coatings, and we quote that geometry in writing before a panel is cut.
What the requirements ask
The ADA requires accessible pedestrian routes to be free of openings that trap canes, heels or wheelchair casters. For steel grating that becomes an opening-size requirement — the geometry of the mesh, not a load test.
Scope — where it applies
Public sidewalks, ramps, building entryways and accessible walkways. The requirement targets the walking surface, while the grating still has to drain surface water underneath.
Key points for procurement
Specify the opening limit or the mesh pattern; we produce close-mesh panels down to 11 × 11 mm and document the geometry with the order. We produce to the requirement — we do not claim a certification we do not hold.
Compliance table
ADA Requirements vs Our Produce-to Position
We produce to requirements — we do not claim certifications we do not hold. Here is how each ADA project requirement maps to our manufacturing position.
| Requirement | What it asks | Our produce-to position |
|---|---|---|
| Opening-size requirement | No openings that trap canes, heels or casters | Produced in close mesh down to 11 × 11 mm or bar spacing to your limit |
| Panel geometry | Bar type, spacing and panel size per drawing | Produced to ANSI/NAAMM MBG 531 reference practice on our lines |
| Surface and finish | Safe walking surface in wet areas | Plain or serrated bars, hot-dip galvanized to ASTM A123 / ISO 1461 on request |
| Compliance documents | Traceable paperwork for the project file | DoC per ISO 17050 with every order; MTC EN 10204 3.1; test reports on request |
| Third-party verification | Independent check of the agreed lot | Third-party testing arranged on request; factory audits welcome |

Opening-size options
Opening Geometry We Produce To
Match the opening pattern to the route, and we produce it to your project's requirement — documented, not just promised.
| Opening pattern | Typical use | Our produce-to range |
|---|---|---|
| Close mesh 11 × 11 mm | Pedestrian routes where openings must be minimal | Produced in press-locked or welded close mesh |
| Bar spacing 30 mm | Public walkways and ramps with standard drainage | Produced with 30 mm centers per MBG 531 practice |
| Serrated close mesh | Wet and sloped accessible routes | Serrated bearing bars at the chosen spacing |
| 40 / 60 mm standard | Back-of-house and maintenance walkways | Produced to standard bar grating practice |
How we support you
Produce to the Requirement, Documents in Hand
Confirm your opening spec
Tell us the opening limit or the mesh pattern required. We confirm we can produce to it and quote the full document set.
Test on request
Third-party sampling and testing arranged for the agreed batch before shipping — reports issued to the project file.
DoC + MTC with the order
Every order ships with a Declaration of Conformity per ISO 17050, an MTC to EN 10204 Type 3.1 and a factory inspection report.
FAQ
Frequently Asked Questions
Can you provide compliance and DoC documents for ADA-compliant grating?
Yes. Every order ships with a Declaration of Conformity prepared per ISO 17050 for the destination market, an MTC to EN 10204 Type 3.1 and a factory inspection report. Test reports on request.
What is the difference between producing to ADA requirements and third-party certification?
Producing to a requirement means panels are manufactured and inspected to that requirement's geometry. Certification is a separate third-party audit program. We state what we produce to and back it with documents and on-request testing — we do not claim certifications we do not hold.
What are your sample and production timelines?
Samples ship in 5–7 working days and mass production runs 15–25 working days after drawing confirmation, both including hot-dip galvanizing. Quote within 24 hours.
