Curve Tube
Posted on Tuesday, August 9th, 2011 at 7:36 amIron Gate Driveway: square tube 2 "by 2" folding vs. train?
An iron gate (18ft. long by about 6.5 7ft. High) is made for my driveway. The top tube design requires 2 "by 2" square tube to be curved / spiral to the extremities. I was told by the guys that design is that instead of bending a tube directly into a curved design / he would cut two spiral designs and join in plates. So basically, it would form the 2 "by 2" section of curved tube by welding together four plates. I was wondering if the strength of a tube is formed is the same as a tube that was once right and it was bent or how to compare the strength? THANK YOU!
Once a tube is folded it has the strength it had before being folded. If you add plates by welding, then you add more strength than you you started with. Do not worry about it. It seems that you are in good hands. Good luck Richard
