2D or 3D? Wall rail over winder treads.
There are two main ways of running the wall handrail through 90º over winder treads, one is using 2D handrail components the other 3D.
By using 2D parts the handrail varies in height above the treads far greater than using 3D component parts.
With the straight sections of handrail, you may notice the change in height, that you may not notice when using 3D parts.
Mitred over winders.
This uses straight handrail and the changes in direction both pitch and horizontal are created by mitres.
The handrail will have to come to level before turning any corners unless round handrail is being used, in which case you can get the profile to match from any angle.
Visually the suits staircases that have straight lines to the top of the stringers, the handrail may then be mitred to follow the changees in pitch to the top of the stringers.
Flowing over winders. 2D.
This uses 2d curved sections coming to horizontal before the corners and using 2d bends to go round the corners.
The main straights will follow the curves to the top of the stringer whenever possible, there may be slight differrence in ordeer to maintain the flow of the handrail.
