i need to bend some aluminum ramps to a more friendly angle for loading and was wondering how best to do it. in the attached photo i need to flatten out the flanges that lay on the trailer that as you can see are about 3/8" thick. can this be heated with a torch to soften the material enough to flatten in a press or by other form of force application? heated steel many times and when it's red it's soft, whats the case with aluminum? can i heat it uniformly and apply force until it moves or will i fracture the material or melt it? i am not going to heat it until it drips, but am i going to damage it, or create some type of blast if heated too much? metal men?
any recommendations are appreciated. TIA
