I'm looking for a vendor who can supply 25-foot long stainless steel tubes / pipes for a "home improvement" project I'm working on. I'm suspending a 24 x 40 foot fabric canopy horizontally over my swimming pool. One (narrow) end of the canopy will be attached to the pipe along the canopy's 24-foot length, so that rotating the pipe via attached handle will wind the canopy up like a big window shade.
The pipe will be supported at the ends by two flanged bearings. In order to keep the canopy reasonably flat (not sagging), it has to be under about 200 pounds of tension, hence the pipe needs to be stiff enough not to deflect much under this degree of lateral force. The force is distributed along the length of the tube, but the tube is supported only at the ends, hence the need for stiffness.
I'm thinking that what I need is stainless-steel pipe, 2 inches OD, with at least a 1/4 inch thick wall.
Now to the question: Where can I buy a couple of 25-foot long stainless-steel pipes, with a 2 inch OD and 1/4 inch wall thickness? Someone must sell these things.
Thanks for any leads.
Kevin
P.S. Any advice on materials or dimensions would also be appreciated. Thanks!
