If you were hurt at work while working, you have a workers comp case and you need to file a workers comp claim. If the angle iron was supplied by a third party and was somehow faulty causing its fall, then you are entitled to sue the third party. I would start off with the workers comp claim, hire a workers comp attorney who can better asses the 3rd party issue.
