Notes

straightening steel tube with heat
To reshape t clamp , the metal must be rendered malleable through heating. To do this, a torch must be carefully employed to ensure the metal does not get too hot - or else it may become brittle. Once the desired temperature has been reached, the steel tube can be bent into the desired form and allowed to cool, thus upholding its restructured state.

To ensure it serves its intended structural purpose, a steel tube must be heated until an even temperature extends throughout its entirety. octagonal pipe of uneven heating, clamping it to a flat surface when hot will allow the tube to cool and remain perfectly straight.

Decorative railings made from steel tubes don't require the same even heating of the entire length. In fact, the process may be simplified by heating only sections of the tube to make it pliable enough to be bent into the desired shape. Afterward, once cooled, the changed form is preserved.
