Intumescent coatings protect structural steelwork by expanding when exposed to fire, forming an insulating char that delays the steel reaching its critical failure temperature. We apply thin-film waterborne and solvent-based systems to columns, beams and bracing, calculated to the section's Hp/A factor and the specified period of fire resistance — typically 30, 60, 90 or 120 minutes.
Steel-framed commercial, industrial, healthcare and residential projects where exposed or concealed steel forms part of the load-bearing structure.
Specification driven by Approved Document B fire resistance periods and the structural fire engineering strategy. Application is recorded against BS EN 13381-8 tested data and manufacturer scope.
- Section-by-section loading schedule and DFT calculations
- Surface preparation and primer compatibility check
- Airless spray or brush application of certified intumescent system
- Wet and dry film thickness records per element
- Topcoat for aesthetic or environmental durability where specified
Confirm the compartment line, service routes, substrate condition and fire strategy requirement before work starts.
Match each detail to a tested system scope, product data sheet and installation sequence.
Deliver the works with qualified operatives, staged inspection and coordination around other trades.
Issue photographs, locations, product records and certificates in a format the client can retain and audit.
