Ramps & Steps

Upstand to contrast visually with the surface of the ramp. Non-slip treads and nosings on steps: a = 170mm (max) b = 280mm (min). For ramps 300mm or more rise, alternative stepped access required.

Gradients: Ramps should have the lowest practical gradient within the range 1:20 to 1:12. 1 in 12 maximum, landings at 2 metres. 1 in 15 and less, landings at 5 metres. 1 in 20 preferred, landings at 10 metres.
