According to the tube's shape the choice the process machine, square rung with rectangle profile by "Expanding machine" and "Flaring machine". Square rung with rectangle can be single section ladder, folding ladder, extension ladder, multi-purpose ladder, industrial ladder etc.

1. After opened holes on profile that will expanding process and made rungs on profile tightly:
