Same pole on each side. Wanting to put 2 doors, each 8ft h x 5ft w, leading to carport need to control dust, I have the door construction idea based on how I am able to make a frame. Thinking drill holes and attach with bolts, can't weld, don't want to damage poles, deforming shape, but holes are acceptable if only option. Any suggestions appreciated, planning to use foam padding against the rock wall so mainly just don't want the frame to be able to rotate when opening and closing the doors. Thank you.
First time asking please excuse any errors in terminology.
