AS 4586 P4/P5 by Gradient
Standard grades call for P4, steeper inclines P5, in line with HB 198 guidance mapping locations to ratings. One-size treatments often fail on steep grades.
Anti-Slip Coating for Ramps
Facility Managers: Gravity Turns a Wet Ramp Into an Incident Report
Loading ramps, carpark ramps, service inclines and egress routes concentrate risk: water runs down them, trolleys and pallet jacks push people faster than they want to go, and one worn patch undoes the whole slope. Stellmann’s anti-slip coating for ramps is CSIRO-tested and certified to AS 4586, with the rating matched to the gradient: P4 for standard grades, P5 for steep inclines and high-risk zones.

What is AS 4586?
AS 4586 is the Australian Standard slip test: the surface is tested wet and given a P rating from P0 to P5, and the higher the number, the more slip resistance it has.
Why Ramps Are the Highest-Risk Pedestrian Surface on Most Sites
Incline Plus Moisture Plus Smooth Concrete or Metal: The Combination Behind Most Ramp Incidents
Slips, trips and falls already drive about 32,000 serious workers’ compensation claims a year, 21.8% of all serious claims in Australia (Safe Work Australia, Key WHS Statistics 2025). Put the same feet on a wet slope and the odds get worse.
Warehousing
A delivery driver slips on a loading ramp in the rain and the WHS investigation asks for the ramp’s slip-resistance documentation.
Public Spaces
An access ramp polishes smooth foot traffic and pedestrians walkways become smooth.
Emergency Egress
An emergency egress ramp is compliant on paper but slippery in a storm, exactly when it will be used.
Distribution Centre
A distribution centre needs P5 on its steep dock ramps and P4 on the gentler service inclines, documented separately.
Every one of these is avoidable. Stellmann's coating reduces the slip risk and documents it at the P-rating each incline demands.
How professional treatment works
Map the Site. Certify Every Slope.
Every ramp is different. The process starts with gradient assessment and ends with per-zone documentation.
1
Profile
Call or send an enquiry. We assess each ramp first: gradient, surface and traffic. Then we match the right Stellmann product and set P4 or P5 per ramp. On-site assessment and slip testing can be arranged for commercial and industrial projects.
2
Treat
Certified installers coat ramps in stages, usually off-shift, so operations keep moving. No acid, no etching, no grinding. Pedestrian zones are cured and walk-ready in up to 12 hours.
3
Verify
Each ramp is certified to its AS 4586 P-rating at the time of treatment and testing, backed by the COMPLIANCE GUARANTEE* on professional jobs (terms and conditions apply).
4
Maintain
Maintenance guide and re-test schedule, so the rating on the certificate matches the ramp underfoot at the next audit.
PEDESTRIAN RAMP SURFACES
Ramp Surfaces We Treat
Ramp mix materials, and each one slips differently. Stellmann's coating is tested and rated across all the common ones.
Concrete
Loading dock ramps, carpark pedestrian crossings, emergency egress ramps.
Metal Surfaces
Steel and aluminium access ramps, dock plates, raised walkway ramps.
Epoxy Floors
Epoxy-coated ramp surfaces in warehouses and distribution centres.
For wheelchair and disability access ramps, see our dedicated wheelchair ramp coating page, which covers DDA and NDIS requirements.
Why it works for ramps
Gradient-Matched. Certified Per Zone. WHS-Ready.
P4/P5 by gradient
Every ramp certified to the class its slope requires, documented ramp by ramp.
Handles contamination
Maintains grip under the water, dust and oil residue ramps collect. Spills should still be cleaned promptly.
Pedestrian-zone focus
Designed for foot-traffic areas: walkways beside vehicle lanes, dock stairs and crossing points, not vehicle lanes themselves.
Off-shift application
Staged, low-odour treatment that fits around operations. Cured and walk-ready in up to 12 hours.
Audit-ready paperwork
Per-ramp certificates, valid at the time of treatment and testing.
Ramp Compliance at a Glance
Compliance is documented at the time of treatment and testing. We recommend periodic re-testing to keep records current.
Work Health And Safety
Employers must maintain safe walking surfaces. Falls, trips and slips are among the leading causes of serious claims (Safe Work Australia, 2025). Documented ramp treatment is part of a defensible position.
National Construction Code (NCC/BCA)
Ramp slip resistance affects building certification, including egress routes that must work in bad weather.
Insurance
Documented slip prevention supports premium negotiations and claim defence after an incident.

Questions, answered
Ramp Coating FAQs
What P-rating does my ramp need?
It depends on the gradient. Standard grades typically need P4 and steeper inclines P5 under AS 4586 with HB 198 guidance. Send the slope details with your enquiry and your free product match will specify the rating per ramp.
Can vehicles drive on it?
The coating is specified for pedestrian zones: walkways, dock stairs, crossing points and foot-traffic ramps. It is not a vehicle-lane product. For mixed ramps we treat the pedestrian path and mark the separation.
Does oil kill the grip?
The coating maintains its rating under the incidental water, dust and oil residue ramps collect, but no surface is immune to a standing spill. Clean spills promptly; the maintenance guide covers this.
Can you treat ramps without stopping operations?
Yes. Ramps are treated in stages, usually off-shift or overnight, and are cured and walk-ready in up to 12 hours. Most sites never stop receiving.
What about our wheelchair access ramps?
They have their own requirements under the DDA and NDIS. See the dedicated wheelchair ramp coating page, or mention accessibility ramps in your enquiry and we will plan both together.
Does the coating change how a gloss tile looks?
On a gloss tile the sheen can change slightly toward satin; that is the only visible difference most customers notice.
