Almost every pull up bar out there, but may not perform as well on speal bars/zinc coated. It's mixed reviews but generally speaking cleaned down bare steel bars as a whole are okay. That being said when we say not as well, we mean how they would be on other bars. They may still perform better than you current grips. But we would still recommend our Elite Lites for chalk free steel bar work or Fibres/Base for chalked steel bars.Do not use with taped bars, doing so will void your warranty
