i built a chicken pen with 1/2 in grey conduit arched from the top horizontal board on my fence to a 2 ft wall 6 ft away from the fence then covered it all with chicken wire

2 10 ft sections would make a large arch....basically a hoop house

i just made another one against my house for a garden to keep the squirrels and possums out....its very sturdy

i didnt use fittings tho.......i got a heat gun and bent the conduit for the door and door frame.....also to flatten the cross piece that holds the arches in place....just heat up one side of the pipe and use another piece to press into it for the arches to fit into....then screw them together

heat gun can be used to many things out of pvc

i would go with the grey stuff cuz i dont think the white stuff is uv protected and will become brittle if its out in the sun......i might be wrong but i know the grey stuff is for outdoors
