Fire Rated Steel Doors For Landmark Public Buildings: Steelguard’s Work On NZICC And Horizon Hotel

Large public buildings need fire protection that is built into the project from the start. In places where thousands of people gather, move through, work, stay or attend events, fire rated steel doors and glazed systems play an important role in helping the building perform safely in an emergency.

The New Zealand International Convention Centre and Horizon Hotel are major additions to Auckland. With the NZICC now officially open, the project marks an important milestone for the city after a complex build, including the 2019 fire outbreak.

Steelguard’s work on the NZICC and Horizon Hotel included large 5m doors and fire-rated steel systems. For our team, this project reflects the level of coordination, fabrication knowledge and fire-rated system understanding needed on major public buildings where safety, scale and architectural intent all need to work together.

Why Fire Rated Steel Doors Matter In Public Buildings

Public buildings are not the same as standard commercial spaces. They often have larger footprints, higher occupancy, complex circulation routes and greater pressure on life safety systems.

Fire rated steel doors help separate areas of a building, protect escape routes, limit the spread of fire and smoke, and support the wider passive fire strategy. They are part of the protection built into the building before anyone uses it.

In a convention centre, hotel or large mixed-use facility, these doors also need to operate reliably every day. They may sit in public circulation areas, service routes, plant zones, back-of-house spaces or large openings where durability, fire rating and access requirements all need to be considered.

Our fire rated steel windows and doors are developed as complete systems. The steel frame, door leaf, glazing, seals, hardware, fixings and installation details all need to work together.

The Scale Of The NZICC And Horizon Hotel Project

Large 5m doors are not simple items. Their size affects weight, movement, tolerances, hardware, structural support, access and long-term operation. When fire rating is also required, the work becomes even more technical.

A large fire rated steel door needs to suit the opening, meet the required level of protection, operate safely, align with the building programme and integrate with surrounding construction. On a landmark public project, there is little room for assumption.

That is why early coordination matters. Before fabrication begins, the project team needs clear information on fire ratings, drawings, door sizes, hardware, access needs, wall details and installation sequencing.

Fire Rated Doors Are Complete Systems

A fire rated door is not simply a strong steel door.

For a fire rated system to perform as intended, every component matters. The frame, door leaf, hinges, closer, seals, glazing, lockset, fixings and surrounding wall connection all contribute to the finished system. If one component is unsuitable, performance can be affected.

This is especially important on large public buildings, where doors may need to handle heavy use, strict compliance requirements and challenging site conditions.

The required fire rating is confirmed by the project’s design professionals, fire engineer and building consent process. Our role is to help identify and manufacture steel systems that suit the rating and project specification once those requirements are known.

Fire Protection After A Major Fire Event

The 2019 fire outbreak became part of the NZICC story, and it reinforced how important fire protection is on major public projects.

Fire rated steel doors and fire-rated glazing are one part of a wider safety strategy. They can help compartmentalise areas, protect key openings and support safe movement through the building during an emergency.

In a building of this scale, fire protection needs to be carefully coordinated. Doors and screens cannot be treated as late fit-out items. They are safety critical building elements with specific performance requirements.

Balancing Safety With Architectural Requirements

Large public buildings need to feel open, legible and well resolved. Fire rated elements still need to support that experience.

Steel is useful because it combines strength with a refined architectural finish. It allows project teams to work with large glazed areas, slim profiles, durable frames and clear detailing where the building requires it.

Where fire-rated openings need to sit alongside non-rated areas, our architectural steel windows and doors can help create consistency across the wider building. This allows fire performance and design intent to be considered together from the start.

The Role Of Tested Steel And Glass Systems

On fire-rated projects, tested systems provide the foundation for safe design. Steel profiles, fire-resistant glass and specialist glazing systems need to be selected around the required rating and application.

Through our Jansen and Vetrotech steel systems, we support projects that require tested steel and glass solutions, detailed system knowledge and strong fire-rated performance.

For public buildings, this can include doors, screens, glazed partitions and large openings where visibility, movement and fire protection all need to be resolved.

Security, Durability And High-Use Performance

Landmark public buildings also need long-term durability. Doors in a convention centre or hotel may be used constantly by staff, contractors, guests, event crews and service teams. They need to remain reliable under repeated use.

Some areas may also require access control, security or reinforced detailing. Where fire performance and protective requirements overlap, early planning becomes even more important. Our security steel windows and doors support projects where strength, controlled access and resilience need to be considered alongside the wider building requirements.

What Project Teams Can Learn From NZICC And Horizon Hotel

The NZICC and Horizon Hotel project shows how fire rated steel doors can contribute to major public architecture when scale, safety and design are all part of the brief.

The key lessons are practical:

• Confirm the required fire rating early

• Treat fire rated doors as complete systems

• Coordinate hardware, access control and installation details

• Consider door size, weight and long-term operation

• Use tested systems where fire performance is required

• Involve steel fabrication specialists before site decisions become fixed

For a landmark building, these details matter. They help avoid rework, protect compliance and support a finished system that works in real conditions.

Fire Rated Steel Doors For Major New Zealand Projects

Fire rated steel doors are a vital part of large public, commercial and institutional buildings. They support the building’s fire strategy while allowing spaces to function as intended.

Our work on NZICC and Horizon Hotel reflects the technical steel fabrication and project coordination required for major developments in Auckland and across New Zealand.

If your project requires fire rated steel doors, large steel doors or fire-rated glazed systems, involve us early. Once the required rating has been confirmed by the project team, we can help identify the right system, manufacture to the specification and support a result built for safety, scale and long-term performance.
