Directly applied fire protection materials for steel structures

摘要

On March 15, 2012, the Canadian Institute of Steel Construction (CISC) held its 14th Associate Professional & Technical Members Meeting in Toronto. I was privileged to be part of a three-person panel presenting on the topic of "Fire Protection of Steel Structures." This article provides additional information about directly applied sprayed fire resistive materials, based on questions asked during and after the presentation. Topics include an introduction to fire-resistance rated structural steel; primers and existing coatings; specification considerations for thin-film intumescent fire-resistive materials; and standards for testing and inspection, application and quality assurance.
