Stairs Handrails

Stairs Handrails

  • Dual height handrails on both sides of interior steps
  • Handrails on continuous  inside edge of stairs with a switchback
  • Stairs with a change in level greater than 500 mm must have continuous handrails on both sides with a 300 mm horizontal extension at its ends. 
  • The handrail should be mounted at a height of 900 mm. An additional handrail shall be provided at a height between 650 mm and 750 mm.
  • Handrails must be separated from the wall surface at least 40 mm. The handrail section and its mounting system should not interfere with the continuous gripping surface.
  • Handrails must have a contrasted reflectance of at least 30 points LRV against its background.

Tactile warning surface

  • For both steps and ramps handrails are to be installed. For ramps or steps wider than 2100mm a intermediate handrail shall be used.
  • When the stair widths are greater than 2100 mm an additional intermediate handrail should be installed. The width between intermediate handrails should be at most 2100 mm.
  • The handrail should be mounted at a height of 900 mm. An additional handrail shall be provided at a height between 650 mm and 750 mm.
  • The handrails must be safely secured. Handrails must have an anatomical design that allows adjustment to the hand with a circular section of 30 mm to 40 mm diameter or an equivalent gripping surface.
