01

Design basis comes first

Intumescent thickness and cementitious build-up are derived from approved system data. Steel geometry, rating and critical temperature matter.

02

Environment changes the answer

Humidity, chemical exposure, impact, exterior conditions and maintenance access affect primers, topcoats, mesh, durability and repair strategy.

03

Compare installed systems

Material price alone ignores preparation, access, coats or build-up, cure time, protection, inspection, repair and architectural finish.

Practical checklist

What to verify

  • Fire rating and design fire
  • Steel section factor
  • Critical steel temperature
  • Existing primer
  • Exposure classification
  • Finish requirement
  • Application access
  • Inspection and maintenance route
Next action

Send the steel schedule, coating specification, primer data and fire-rating basis for a system comparison.
