K series LH series and DLH series open web steel joists and joist girders (this is a technical difference between S, J, and H series joists more than anything, the difference to the owner is non-existent, it makes a difference to the engineer) Old - (and pretty much gone) Guidance Information - Bulletin No. 1002 Painted Steel Joists In dry interior-use conditions, fireproofing can be applied directly to primed/painted joists without use of metal lath. No bond testing is required. Painted Structural Steel Spray Applied Fire Resistive Materials are almost always fire tested on unprimed/unpainted struc-tural steel.
Intumescent coatings, often referred to as intumescent paint, are used in buildings as a passive fire resistance measure. They can be applied to structural members as an aesthetically pleasing fireproofing product. Another type of intumescent product is a firestopping pillow or putty that is used to protect openings from fire. Looks like an intumescent paint as suggested by Mark. From a fire-protection perspective it makes little sense to coat the sides of the members and not the bottom, plus that engineered limber (or solid lumber) will last longer in a fire than steel bar joists, which tend to twist and sag when they get hot.
