We have a new range of Fire Doors! Have a read through this page to learn more about our new GRP (glass reinforced polyester) Hinged Fire Doors. Learn why they are better than any other fire door option in the New Zealand market (literally!).

Ulti Group’s latest door system added to our extensive range is the GRP Hinged Fire Doors. These meet over 90 independent tested specifications compliant with worldwide regulations, including being certified to New Zealand standards. Our fire rated door systems provide up to 240 minutes of fire resistance.

Unique to Ulti Group, a concealed intumescant strip is built into the door during the manufacturing process. This maintains a smooth, seamless profile ensuring that there are no seams or ledges where dirt and germs can gather. The intumescent strip is activated by the heat of a fire and expands to create a sealed fire door.

Completely smooth and seamless gelcoat finish which is non-porous and non-shedding. Free from organic materials, ledges, recesses or right angles, for flawless hygiene.

Designed, tested and certified to meet the most stringent fire certifications. Completely heat resistant and designed to withstand areas with high humidity and extreme temperatures.

Exceptionally strong, lightweight and impact resistant. These doors outperform wood and steel alternatives, bringing you a lifetime of durability and the ultimate cost-effective solution.

Inorganic closed cell core which does not corrode or absorb moisture. Remains unaffected from exposure to water, steam, disinfectants, chlorine and strong chemicals including H2O2; even after decades of use.

Proven to maximise efficiency, safety and hygiene in the most demanding environments. These doors will not rot, rust, swell, warp or corrode.
