AS 1657 explained
What AS 1657 Means for Grating
AS 1657:2018 is the Australian standard for fixed platforms, walkways, stairways and ladders — the design rules that decide how access flooring performs. We explain where grating sits in it, and we produce to it. In practice, an AS 1657 walkway grating spec turns on clear span, bar spacing and edge support, and those are exactly the details we quote against in writing.
What AS 1657 is
AS 1657:2018 sets the design, construction and installation requirements for fixed platforms, walkways, stairways and ladders in industrial and commercial buildings. Loading is determined under AS 1170.1, and grating is the flooring material for most walkways and platforms.
Where grating sits
Grating panels carry the live load on walkways and platform floors — as serrated or plain floors, in standard or heavy-duty bar size, spaced and supported per the engineer's layout.
Key points for procurement
Tell us the span and the AS 1170.1 live load. We match bar size and spacing, produce on our in-house lines, and issue load tables and documents with the order.

AS 1657 Requirements vs Our Produce-to Position
We produce to standards — we do not claim certifications we do not hold. Here is how each AS 1657 project requirement maps to our manufacturing position.
| Requirement | What it asks | Our produce-to position |
|---|---|---|
| Flooring on walkways & platforms | Grating panels carry live load per AS 1170.1 | Bar size and spacing matched to the span; load table issued with your quote |
| Slip resistance | Safe underfoot in plant and outdoor use | Serrated bars standard for wet and oily areas; plain on request |
| Stairways & landings | Treads and landings per AS 1657 geometry | Cut, banded and nosed to your drawings on our in-house lines |
| Fabrication details | Cutting, banding, toe plates | Cut and banded in the workshop to your layout |
| Compliance documents | Traceable paperwork for the project file | DoC per ISO 17050 with every order; MTC EN 10204 3.1 and test reports on request |

FAQ
Frequently Asked Questions
Can you provide compliance and DoC documents with an AS 1657 grating order?
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. Load and test data are supplied on request.
How does AS 1170.1 loading affect the grating you produce to AS 1657?
AS 1657 references AS 1170.1 for the dead and live loads on walkways and platforms. Tell us the span and the live load, and we match bar size and spacing so the panel carries it, and we issue a load table with your quote.
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.
