Anti-slip Grating "Serrated"
When oil, moisture, icing or similar conditions increase the danger of skidding on platforms or catwalks,
Serrated Grates and treads with their non-slip notches offer a very good grip.

For high requirements of anti-slip protection, such as for inclined gangways with a pitch a (alpha) of 10-24 degrees, we recommend equipping the grating with tread strips.
