Thickness for Passive Fire Protective Coatings

Bob Glendenning from Sherwin-Williams talks to Structure Magazine about the safest way to determine fire protection thickness for steel structures.

For structural steel fire-resistance ratings, Underwriters Laboratories (UL) has stated it is not safe to make assumptions about intumescent coating thickness for steel components using extrapolation data. Bob Glendenning, Global Fire Engineering Manager at Sherwin-Williams, relays why this could be potentially hazardous and why it doesn’t work. Discover how important it is for structural steel engineers to work directly with a credible coatings supplier to define safe alternatives.
