Passive fire protection for structural steel and timber. Engineered coatings that protect your building, your people, and your compliance.
Intumescent coatings are a specialised form of passive fire protection. Applied like paint, they remain thin and unobtrusive under normal conditions. When exposed to extreme heat, the coating expands up to 50 times its original thickness, forming an insulating char layer that shields structural steel and timber from fire.
This buys the most valuable thing in a fire: time. Time for occupants to evacuate, time for emergency services to respond, and time before structural elements lose their load-bearing capacity.
At ST Coatings, we supply and apply certified intumescent coating systems for commercial, industrial, and multi-unit residential projects across Auckland and the wider region.
Structural steel must achieve specified Fire Resistance Ratings (FRR) under the Building Code. Intumescent coatings are a proven, certifiable way to meet 30, 60, 90, and 120 minute ratings.
Unlike board systems or sprayed fireproofing, intumescent coatings add only millimetres to the steel profile. Architectural steelwork stays visible and clean.
Intumescent systems can be top-coated in a wide range of colours, so fire protection doubles as your decorative finish.
We apply both thin-film systems for internal steel and durable systems rated for exposed or semi-exposed environments.
Tell us about your commercial painting project and we’ll provide expert advice and a detailed quote tailored to your requirements.
We review your fire engineering requirements, steel sections, and required FRR, then specify the right coating system and dry film thickness.
Correct preparation and priming is critical to performance. We prepare all substrates to the coating manufacturer's specification.
Our applicators apply the system to the specified thickness, with wet and dry film measurements taken throughout.
We provide full documentation of film thickness readings and product batch records to support your producer statements and council sign-off.
Experienced, trained applicators. Certified coating systems from leading manufacturers. Full QA documentation for compliance. One contractor for your protective and decorative coating needs.
