Reply:FYI You would be hard pressed to find any Hollow Section Steel (HSS) that is not A500
Reply:Anybody know the difference between A500 and A513 ?P.S. Anybody who answers "13" gets
Reply:Its not the A500 its the -C that is uncommonThe common sq tubing at the steel yards is A500-BA500-C has a higher tensile strengthJust wasn't sure if it needed preheating or a harder wireCody WernerFABCONwww.fabconwelds.com
