Re: Helical Steel Stairs Question

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I hope you mean hot-rolled channels and not cold-rolled, because cold-rolled channels are light gauge 
and will buckle or crush in the rolling machines.

> I've been asked to provide a design for a residential steel stair that has a double helix twisted shape, approx. 10 ft. high and has a 180 degree radius.  I plan on using cold rolled 12" channel for the stringers with welded z-shaped plates for steps.  The stairs will be wrapped in wood.  Any 
suggestions on how to calculate this or other recommendations are much appreciated.
