Permanent ramps are structured of concrete, such as the ramp shown below and is ideal wherever regular wheelchair access is required.
With a non-slip surface, side upstands and easy grip handrails, it is equally suitable for ambulant users with reduced mobility.

What length ramp do you need?
For fixed concrete ramps, Building Regulations would generally suggest a gradient of 1 in 12 (e.g.: a 3″ height would require a 36″ ramp).
However, this is a guideline, and not a legal requirement. If space permits, this is the ideal gradient, but often the height that needs to be bridged is too great to allow such a length, particularly on narrow footpaths etc.
Where only occasional use of a portable ramp is required, for powered scooters / electric wheelchairs (or a manual wheelchair with assistance), a gradient of 1 in 6 is adequate. (e.g.: a 6″ step requires a 36″ ramp).
