Exclusive to ACO, these grates are rated up to R11 (oil wet ramp) and V (wet pendulum) AS/NZS 4586:2004, Slip Resistance Classification.
Grates with raised mechanical nodes have excellent durability compared with those produced by manufacturers who apply coatings or mechanically alter (e.g. blast) to attain a level of slip resistance. These processes will not only ensure a short-term slip resistance due to the wearing process but can introduce impurities in the material which will accelerate corrosion.
