  • bedframe angle iron what is it ?

    hi,i'm new to welding, had my mig about 5-6yrs now. i'd describe my welding efforts as more of sticking metal together then true welds,but i got the hankering to stick with it ,and to practice more, now comes the question is bedframe angle good for or rather, does it have structural quality?because it's free i always keep plenty in my shed on hand so far i have only used it for making shelves and adapting implements to my tractor.it also saved the thirty nine dollars spent on the thin as paper mig cart i bought from harbor frieght [reinforce all the weak points it's great now i can carry the big tank of argon]but to my current project i want to use it for long trailing arms to support a snow blade on a gt to the rear axle maybe weld it to black pipe[ also free] to form arigid beam to transfer load to rear,have you gotten idea i don't want to buy steel if i can help it .thanks for any insight on matter dave don.

    Its just light duty HR steel, perfect for light jobs and the angle is usually FREE...Bob

        Hot Rolled is the steel with the scale on it, Cold Rolled CR is smooth...Bob

          The bed frame that I have worked with is much harder and brittle than plain old HR steel. I have read that bed frame can be made from recycled steel so it can have impurities and contents that make it harder. I ruined a standard ( not bi-metallic ) bandsaw blade on that stuff and wound up cutting my project with a 4.5" cutoff wheel on an angle grinder. It seems to weld OK.

            steelshot,
            I used bedframe for making part of the new base for my 4x6 bandsaw. Bedframe is good for that kid of stuff. If you are making or modifying your welding cart, then its OK for that kind of stuff. For something more structural, I'd use steel with a known composition.

              That stuff is harder than woodpecker lips! Ever tried to drill a hole in it? YIKES!

                hot roll cold roll

                i gather heat is used for forming hr and that and pot steel is why it is harder ,cold roll is fomed cold and is a rated hardness??

                  Steelshot,

                  Ahhh, Mystery Metal! Fun stuff! Most bed frames made toaday are made from what Bob said - light gauge HR steel, and they weld, cut, and drill fine. Good for non-structural stuff. BUT if you get hold of an older frame that has some weight to it and has angle that you can't twist a lttle bit in your hands, it's a way different story. That's the Mystery Metal stuff - and it is HARD! I don't use it for anything at all.

                    I've found used rebar that was too hard to bandsaw cut. One local used steel yard will not cut any rebar-they don't have a cutoff wheel setup.

                      Some bed frame steel is made from old railroad rails which is high carbon steel.

                        I’m nearly done building a tire rack in my garage and I used some scrap bed frame material. Overall it’s very low grade steel, it does TIG weld just fine…but you notice how weak it is when you try to bend it. I made some brackets out of the angle iron bed frame and when I bent it, the metal cracked/tore a bit. Not a big deal in my case as I just TIG welded the crack and ground it smooth. I wouldn’t trust a bed frame material on anything that would see vibration or any large amounts of loading, so it’s ideal for static applications…ie: bed frames.

                              Cold rolled steel is hot rolled that has been further processed by cleaning and sending it through rollers (hence the name) that squeeze it to a very uniform size and thickness. Because of this, it should be somewhat harder than the same steel that is not rolled. It can be Annealed however, making it soft again and equal in hardness to the HR stuff.
