Dear guys: I'm not experience in bending Square Hollow Section beams. Currently I'm using a 100mmx50mmx5mm Steel beam, but planning to make a bend. Any Rules of thumbs for cold bending? I could be bending on the 50mm side and/or 100mm side. Any articles that one can find for the heat to use for bending? In addition, and the resulting strength that I can achieve if I'm putting a minor load onto the bended beam?
