    Google intumescent paint. When you buy it make sure you get a certificate with it and make sure you get a product data sheet and instructions. It is only paint but the instruction is required to tell you how many coats you need to reach the required standard.

    Agree with everything said here. I'd try the likes of MRCB or Igoe international.

    Hmm...this sounds like it's the sort of question that might need off-boards help.

    Do you mean fire-proof as in a coating that expands to protect the steel from fire, or just a paint that doesn't burn?

    If the wall that's been removed was fire-resisting, for how long was it fire-resisting (e.g. 60 minutes, 120 minutes etc?) and was it protecting an escape route?

    To provide protection, the right amount - not too much, not too little - must be applied in the right layers, and you must be sure you've specified the right level of protection.

    There's a bit to think about (and consequences if you get it bad) so I'd advise getting professional advice (did you have an architect/engineer size the RSJ? S/he might be of help) to ensure that the home/building you're talking about is as safe as it needs to be under the Building Regs.
