I am building an outside metal handrail because I was unhappy with the ones from Home Depot, Walmart, E-Bay and Lowes. You would think that EBay would have what I want, but it seems as if it is all the same things. The closest that I found was

but it is not inclined.

....

That is, according to the description,

"Rackable to a range of 0° to 41°"

which would seem to suit the purpose.

Alternatively, find a local wrought iron specialist.
