1 inch steel telescoping tubing shortage
(OP)
We use alot of 1 inch square telspar (telescoping) tubing and are having difficulties obtaining this material. Which will cause all sorts of problems. Does anyone know of any alternatives to 1 inch square telspar steel tubing? This could be a place that still has the material available, or an alternate material that can be used in its place.
Thanks
Thanks

Load, temperature, corrosion duty, vibration, etc?

Note the spelling; perhaps you are just asking for the wrong stuff.

You might check out other Telespar distributors for stock if you are willing to pay freight from out of your region.

As for duty cycle, the material would be used in mobiilty equipment (power scooters and wheelchairs). You can imagine, overall, a fairly lax duty cycle accordingly. Mostly indoor usage and little exposure to any corrosive elements. Granted it would still need to function in cold weather and could not be ruined by an unexpected rain shower.
MikeMech- That explains alot...that has been the impression we have gotten. The fab shop we get most of our steel parts from has not been able to get this material in like they used to be able to. Since it is very critical to what we make, we are just stepping in to try to find alternatives.
Thanks again.

Mcmaster is quoting a 2 week lead time.

I strongly suspect that "overuse" (over-stress or severe loads) are going to actually be more common in this application than you'd (logically) expect.
People will beat up (mis-use) the things closest at hand and most frequently used. Not just falls or heavy loads or two people sitting in the chair at the same time, but stupid things like a 16 year old jumping on the wheelchair and rolling down the driveway playing with "with friends" - Getting the chair stuck in an elevator and having the door squish it - and, of course, the safety interlock will fail at the exact wrong moment, Murphy's Law being what it is.
I'd plan on loads being two or three times what you's "expect" to have. Just because you plan on reasonable behavior by sensible people doesn't mean some lazy nitwit is going to try to hang three weeks worth of filled grocery bags on the handle and try to steer their way out of WalMart.
