Intumescent steel protection

Architectural fire protection for exposed structural steel in interior and exterior applications

Modern design practice has increasingly incorporated architecturally exposed structural steel, or AESS. Originally used by structural engineers as a highly elaborate exoskeleton, AESS has evolved into an outlet for both engineers and architects to integrate components of their work into the visibly finished structure. If these exposed design elements are also part of the primary structural components of the building, the integrity of the structural steel must be protected with an intumescent fire protection coating.

Hilti's Intumescent Steel Protection portfolio has expanded to now offer solutions for both water-based and solvent-based fire proofing. Also known as IFRM, these products are optimized for architecturally exposed structural steel in interior and exterior applications with approved top coats.
