Building stairs with UPM ProFi Rail Step
Support Rails to be attached on flat surface, like concrete stairs.
Decking boards must be installed with UPM ProFi Alu Rail (instead of T-Clips) for more stability.
If the existing construction cannot be changed to match the dimensions of UPM ProFi profiles, best is to use UPM ProFi Rail Step at the front stair edge and UPM ProFi Deck boards in the internal corners. If needed, the deck boards can be cut lengthwise to fit the dimensions of the stairs.
