A handrail is a rail that is designed to be grasped by the hand so as to provide stability or suppor. Handrails are commonly used while ascending or descending stairways and escalators in order to prevent injurious falls. Handrails are typically supported by posts or mounted directly to walls.
In morden socity, there are many types of stair railing. Normally we will make the staircase from round shape pipe then do the second roll forming. In the market there are many types like oval pipe, square type and some specail shape, here are some pictures for your reference:
For the main roll forming machine, we take the round pipes as material and by the roller rolling forming to change the round pipe shape to this specail shape. So by this way, the machine working method is manual version. Here are some main parameters for your reference:
