ADA explained
What ADA Means for Bar Grating
The ADA requires accessible pedestrian routes to be free of openings that can trap a cane tip, heel or wheelchair caster. For bar grating, that is an opening-size geometry question — and we produce to it. An ADA-compliant bar grating panel is therefore built on close cross-bar spacing with the opening held within the required envelope, rather than on any special coating or finish.
What ADA asks of grating
Accessible routes must not have openings that can trap a cane tip, heel or wheelchair caster. For bar grating that is an opening-size and geometry requirement, not a material or load test.
Scope — pedestrian access routes
ADA applies where the public walks: sidewalks, ramps, building entryways and accessible walkways. The grating must keep openings small while still draining surface water.
Key points for procurement
Produce close-mesh panels (down to 11 × 11 mm) or bar spacing sized to your project's opening limit. We state the geometry we produce to and document the panels — we do not claim a test 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 | Openings small enough for canes, heels and 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 for ADA Bar Grating
The opening pattern is the whole story for ADA-style grating. Here are the options we produce, matched to where each belongs.
| 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 bar 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 opening sizes can you produce and what are your timelines?
Openings down to 11 × 11 mm close mesh and bar spacing from 30 mm upward, produced to your project's heel-proof requirement. Samples ship in 5–7 working days and production runs 15–25 working days after drawing confirmation.
