Achieve easy building compliance with certified intumescent coatings for steel

  • Protect your structural steel with high-performance passive fire protection that meets strict New Zealand building codes.
  • Avoid costly project delays by working directly with an owner-operator who personally manages your site application from start to finish.
  • Get rapid council sign-off with precise dry-film thickness testing and official PS3 certification provided upon completion.
Our specialist team applies intumescent coatings to steel in Christchurch, Canterbury and across the South Island

On-site application for your intumescent coatings for steel project

Dedicated on-site spraying for large-scale South Island projects
Your structural steel gets high-volume protection applied directly at your construction site. Experienced applicators travel straight to your location with heavy-duty mobile spray equipment to coat universal beams, columns, and portals. This gives you full coverage that fits perfectly around your busy building schedule.
On-site application only due to steel size and weight
You get peace of mind knowing your steel is managed directly on-site to maintain absolute safety. Because structural steel is incredibly heavy and large, and because of workshop space limits, off-site coating is strictly unavailable for steel. Every beam is prepped, primed, and sprayed right where it stands, preventing transport damage or logistical headaches.

Premium fire-resistant paint for steel finishes tailored to your engineering design

Industrial matte white and tinted topcoats for exposed steelwork
Your building design can proudly display its structural elements with clean, modern matte finishes. These systems provide a sleek look for visible internal steel structures, columns, and stairwells while delivering required Fire Resistance Ratings (FRR) from 30 to 120 minutes.
Heavy-duty protective primers and durable fire-retardant layers
Your steel stays protected against corrosion and moisture as well as fire. Specialised priming systems ensure the fire protection bonds perfectly to raw or pre-primed steel, giving you long-term durability in high-humidity or exposed architectural designs.

Complete intumescent paint for steel coverage across the South Island

Your structural project gets reliable local expertise and fast turnaround times, no matter where you are building. Straight Cut Intumescent provides complete compliance coverage to protect your steelwork across all major southern towns.

Frequently asked questions about steel coatings

Intumescent coatings for steel are specialised fire-retardant coatings that react when exposed to extreme heat. Steel does not burn, but it loses its structural strength quickly in a fire. This paint grows into a thick, protective layer of carbon foam (char) that insulates the steel. This keeps the steel cool and stops it from buckling, buying critical time for people to get out safely.

No. While smaller timber jobs can be treated offsite, all structural steel coating must be completed directly on-site. The extreme weight and size of heavy steel beams, combined with workshop space limitations, mean on-site spraying is the safest and most efficient way to protect your steel without risking transport damage to the fire-retardant layer.

You receive a comprehensive compliance package required for local council sign-off. This includes accurate dry-film thickness (DFT) readings measured with specialised electronic gauges, alongside a signed PS3 (Producer Statement) certificate. This proves the correct product volume was applied to meet the specific Fire Resistance Rating (FRR) in your engineering design.
