DD-5413 Anti-slip stair edge profile

DD-5413 anti-slip stair nosing profiles for step edges. Select by step dimensions, substrate and fixing method.

Selection and application

Measure step width and edge shape. Check contrast, fixing and the stated slip resistance of the profile. The selected design must suit the staircase and its use.

Stair edge profiles reduce the risk of slipping on stairs.

" Accident hotspot stairs "

Staircase accidents have always been a major concern. This applies to the home and leisure sector as well as the workplace. The frequency and severity of these accidents necessitate a concerted effort to develop preventative measures.

Slip resistance

Regarding slip resistance, a minimum rating of R9 is required for stair treads in work areas, unless specific lubricants and job requirements necessitate a higher R-value. Ratings R10/V4 or R11 are recommended for entrance areas, stairs, and landings outdoors. ... To prevent slipping, anti-slip stair edge systems (edge profiles, strips, etc.) should have a minimum width of 3 cm to 5 cm for stairs with an incline α ≤ 30° and a minimum width of 3 cm for stairs with an incline α > 30°, and should be installed directly on the leading edge. ...

Color coding

Stairs and steps become more easily recognizable through color differentiation/marking.
e.g. if
– The tread and riser are designed in different colors,
– at least the first and last steps are marked with a step edge marker,
– Step edge profiles, strips, etc. offer a brightness and/or color contrast to the rest of the tread surface" ( %2Fwww.baua.de% 2FDE %2FAngebote% 2FPublikationen %2FPraxis% 2FA21.pdf %3F__blob% 3DpublicationFile&usg=AOvVaw2ugDPajhHOz1rnjsbMr_oP" target="_blank" rel="noreferrer noopener">Source: Federal Institute for Occupational Safety and Health: Functional, safe and user-friendly stairs )
