Methods of Fire-Proofing Steel
Methods of Fire-Proofing Steel
(OP)
Hi guys
This is probably a question that I can post in the Steel or Structures Other Topics forum but I have been getting such a great response in this forum I will try here first, particularly now that the Australian participants on this site are increasing.
How do I go about achieving fire-rating for bare steel and will bare steel (SHS/HSS column) be able to achieve any fire-resistance on it's own?
I have read many methods to fire-proof steel include encase 50mm of concrete to each side, drywall boxing the section with a fire-rated product, coating the section with intumescent paint, coating or spraying the section with fire-proofing material and boxing the section out with unrated drywall.
How much fire-resistance is achievable with each method and what codes/reference material should I be looking at to find out this information?
Can I also be directed to some good manufacture's of any fire-rating materials that anyone should know of.
Any help will be appreciated.

RE: Methods of Fire-Proofing Steel
Fire rating for bare steel is determined in accordance with AS4100 ch12. My experience is that you get very little fire resistance out of untreated steel. I have always achieved fire rating by boxing out with Fyrchek - CSR product. Download the CSR 'red book' - has plenty of info. If your columns are large enough concrete filling may also be an option.
Cheers

For less generic advice refer to the manufacturer.
Intumescent paint should be an option, but last time I tried in Melbourne it was knocked back by the building surveyor. This was 6 or 7 years ago, acceptability has probably improved by now.

They ASI gives this out for free, thought you may be intrested in reading it.
