The Cable Connection Check out our DIY cable railing kits. They are economical and easy to install.

rilgen Your DYI kits may be economical and easy to install, but the last time I check cable 'runs' were straight. And, yeah I know that a curve is a series of straight lines, but how many posts would I need to cover a quarter circle with a 22' radius?

Judy M Have you looked through the photo section and typed "curved railing" in the search? Lots of ideas there, one might spark a solution.

Dytecture Unfortunately it is more difficult to fabricate and install with curved surfaces. If cost is a concern it might best to change to a more rectilinear design.

The Cable Connection With recommended cable support spacing of 42" you would need approximately 10 posts.

Ironwood Builders The stainless construction you had quoted is also a major cost factor. A powder coated steel top rail and ousts will lower costs. Combined with a horizontal cable rail system, tour cost could make the "cool" radius deck do-able.

The Cable Connection Here's one example.

Ironwood Builders And another.

rilgen Ok, vertical cables might be a solution. Can anyone give me a ballpark cost per linear foot for the powder coated steel rails and post, with ss cables?

The quarter round deck has a radius of 22' so the curve portion of the railing would be about 34'. That would connect to a straight section for 20', a 90 degree turn to another 10' straight section leading to acouple of stairs to grade.

The Cable Connection Here's the list of metal railing fabricators to choose from. They can give you quote for what you need.
