In the case of sanded gratings, the surface is subsequently coated with corundum sand (GRP-BK grating type) or quartz sand (GRP-BQ grating type). The sanding is applied with a resin after the grating has been manufactured.
Gratings type BK – with corundum sanding, are particularly suitable for wet areas or for areas where lubricants and oils are used. This grating type achieves serration class R13
The quartz-sanded Gratings are often used in barefoot areas such as swimming pools. This type of grating also achieves serration class R13.
