Serrated When the gratings are used in particularly wet environments or in places where extra non-slip properties are required, serrated bars will be an advantage. The serrated process involves carving a pattern in the bars to be serrated. This could be in either the control or filler bars or in both control and filler bars and bearing bars, depending on whether the grating needs serrated in one or both directions. Serration is available in two patterns: small serration and large serration
* Small Serration Small serration is the most commonly used serrated form, which is used for industrial walkway and staircase gratings etc. and for heavy duty ramp gratings.
* Large Serration This type of serrated is very easy to clean and therefore primarily used in industrial kitchens, canteens and in other places with high hygiene requirements and requirements of non-slip properties. Serrated bearing bars and control and filler bars.
