Anti-slip strips on stair treads.

Transparent anti-slip coating as anti-slip strip on stairs for permanent slip resistance.

Stair treads accompany us constantly in everyday life, from the single step on the sidewalk to staircases with several floors. Consciously, we often do not even notice the steps and our movements are automatically adjusted to the height and width of the tread. Whether this is slip-resistant depends on the coefficient of friction of the surface. The smoother the material surface, the lower the adhesion. If the surface of the steps is contaminated with dirt or wet, this reduces the tread resistance enormously and who of us keeps his eyes constantly on the next step to be climbed when climbing stairs?

A hundred years ago, the staircase of the Springli schoolhouse was built for eternity, and so it impresses with its gray stone and black metal grates.
The stone steps of the staircase have been trodden smooth by the many steps that schoolchildren took in and out of there over the past decades. And, of course, in that time the general perception of hazards has changed. The terms occupational safety and accessibility are no longer empty words, but have been brought to consciousness by legal regulations and standards, among other things.

An anti-slip coating was chosen as the solution for the slip resistance of the stair treads. The 103 steps were coated in the form of 10 cm wide anti-slip strips. When stepping on the steps, the anti-slip coating automatically achieves a higher adhesion with the slip resistance factor R11, i.e. the step is tread-proof.
