Grating Steps

Antivertigo System

The NO-PANIC ANTIVERTIGO GRATING is a patented exclusive system by Nuova Defim Orsogril. The special shaped profiles provide total screening down, while keeping the typical airflow grating characteristics. The step designed using this grating type complies with current anti-skid norms; ANTIVERTIGO landings and walkways grating are also available upon request.

Landing. For landings composition, the system foresee a starting panel provided with “nosing” and a variable number of interlocked panels to reach the desired length. The panels are joined together by a "dovetail" system between the frames. This solution grants the visual continuity between adjacent panels, hiding the junction points.
