Stair railings consist of posts, handrails and filling. Posts and handrails carry the main load. For greater rigidity, the ends of the railings are attached to the walls. The handrail also serves as a handhold when walking up the stairs. It should be comfortable to hold. It can be a metal pipe or wood. The tree is difficult to connect at turns, so it is used less often. However the wooden handrail gives warmth and unique coloring to custom railings.
