Slip Resistance Grating – choosing the right top surface
The slip resistance of the flooring and walkway profile is an essential consideration in any grating project. Standard steel grating comprises plain square edge flat bars. In order to increase slip resistance there are a number of options available for consideration, especially for sloping walkways.
As mandated by AS 1657-2013, the use of 10 x 10mm square bar cleats is required for additional security under foot on walkways with a slope >100. Note: ISO 14122.1 recommends cleats between 10° and 20°.
Serrated grating improves slip resistance (Stainless steel grating and any bars <25mm or >75mm deep will not be serrated.) In addition steel and stainless steel grating can improve its slip resistance by setting the direction of walking over the floor, parallel to the load bars.Pattern choice is also important; grating patterns with 100mm cross rod centres (ie Pattern A and C) have better slip resistance than those with crossrods at 50mm centres.
