Thunderbolt®PRO - Galvanised Rod Hangers: Designed to Meet AS 2419.1:2021 Fire Hydrant Installation Standards.

Fire hydrant systems demand performance under pressure, literally and figuratively. ICCONS® is proud to introduce Thunderbolt®PRO - Galvanised Rod Hangers, Australia’s first and only single-piece galvanised, Fire-Tested, C2 Seismic Assessed rod hanger Screw-bolt, a market-first solution engineered to meet the most stringent fire, seismic, and corrosion protection standards as set out in AS 2419.1:2021: Fire Hydrant Installations.

This market-first solution eliminates the compromises traditionally associated with rod hanger compliance and delivers a fully tested, off-the-shelf fixing system.

Explore ICCONS’ full range of Fire-Tested, C2 Seismic Assessed Rod Hangers for Australian construction standards.

Why Compliance matters in Safety-Critical Environments

Under AS 2419.1:2021 Fire Hydrant Installations, pipe supports and associated fixings must meet strict performance requirements, including:

Until now, no rod hanger Screw-bolt available in Australia met all three requirements simultaneously for C2 seismic environments, particularly in a galvanised finish commonly specified for fire hydrant pipework. ICCONS’ Thunderbolt®PRO - Rod Hanger with it’s Galvanised, C2 Seismic Assessed, Fire-Tested, rod hanger closes this long-standing compliance gap.

Why Thunderbolt®PRO – Galvanised Rod Hangers

✔ C2 Seismic Assessed:  Suitable for the highest seismic performance category defined in AS 5216 “C2”
✔ Fire Tested: Independently assessed for performance in fire-rated environments
✔ Mechanically Galvanised: Corrosion protection` ideal for hydrant system applications

Together, these features support compliance with AS 2419.1:2021 Fire Hydrant Installations, and provide confidence for engineers, hydraulic consultants, and fire services contractors. 

Key Performance Features of Thunderbolt®PRO – Galvanised Rod Hangers

  • National Code compliance
  • ETA assessment
  • C1 and C2 seismic assessment
  • Fire-rated performance
  • Compatibility with ICCONS® DesignPRO anchor design software
  • Straightforward installation using the Thunderbolt®PRO Rod Hanger system
  • This makes specification simpler and reduces compliance risk during design, installation, and inspection.

Applications and Uses of Thunderbolt®PRO – Galvanised Rod Hangers

The Galvanised, Fire-Tested, C2 Seismic Assessed  rod hangers are suitable for:

  • Fire hydrant pipe supports
  • Seismic bracing for suspended MEP services
  • Essential services in Importance Level 3 and 4 buildings
  • Retrofit and upgrade works in high-risk zones

Designed for Fire Hydrant and Safety-Critical Applications 

Fire hydrant pipework is often installed in basements, plant rooms, riser shafts, and other exposed service zones. Fixings in these locations must continue to perform under seismic loading, resist corrosion over time, and maintain structural integrity under fire conditions.

ICCONS® developed this product specifically to provide engineers, hydraulic consultants, and fire-systems contractors with a one-product-fits-all solution. This eliminates the need to piece together multiple compliance pathways or settle for lower performance fasteners.

Designed by Demand

Recent correspondence from leading fire service contractors highlights a critical lack of compliant rod hanger options for fire hydrant installations. This product directly responds to those needs. With no other Galvanised, C2 Seismic Assessed, Fire-Tested rod hanger available in Australia, ICCONS’ innovation sets a new benchmark for safety, compliance, and engineering certainty.

Leading the Way in Compliance and Confidence

As safety and design standards continue to evolve, particularly for seismic and fire-rated applications, ICCONS® remains committed to innovation and technical leadership. Our new galvanised Fire-tested, C2 Seismic Assessed rod hanger isn’t just the first of its kind, it’s also a powerful example of how thoughtful engineering can simplify compliance while improving project outcomes.

Key Takeaways and Benefits

ICCONS’ fire-rated C2 seismic assessed anchor delivers a fully compliant rod hanger solution for safety-critical installations. Independently fire tested, C2 seismic assessed to AS 5216, and finished with mechanical galvanisation for corrosion resistance, it meets the key fixing requirements for fire hydrant systems under AS 2419.1:2021. The single-piece design simplifies specification and installation while providing long-term performance and compliance certainty in exposed and high-risk environments.

Frequently Asked Questions - Galvanised C2 Seismic Rod Hangers

1. What is a C2 Seismic Assessed rod hanger under AS 5216?

A C2 Seismic Assessed rod hanger is a fixing that has been assessed to AS 5216 for the highest seismic performance category (C2). C2-rated anchors are suitable for critical services where continued performance is required during and after a seismic event, including fire hydrant and essential services installations.


2. Why must fire hydrant rod hangers be fire tested?

Fire hydrant systems are life-safety infrastructure and must remain operational during a fire. AS 2419.1:2021 requires pipe supports and associated fixings to be fire tested to ensure they maintain structural integrity under elevated temperatures and fire exposure.

3. Why is galvanisation important for fire hydrant rod hangers?

Fire hydrant pipework is commonly installed in exposed environments such as basements, riser shafts, and plant rooms. A mechanically galvanised rod hanger provides long-term corrosion resistance, helping ensure durability, reliability, and ongoing compliance throughout the service life of the system.


4. Is this rod hanger compliant with AS 2419.1:2021?

Yes. The ICCONS® Thunderbolt®PRO - Galvanised Rod Hanger has been engineered to meet the Fire-Testing, Seismic Assessment, and Corrosion resistance requirements outlined in AS 2419.1:2021 – Fire Hydrant Installations, including suitability for C2 seismic environments 


5. How is this different from a standard rod hanger anchor?

Most standard rod hanger anchors are not fire tested, not C2 seismic assessed, or not available in a galvanised finish. ICCONS’ solution is Australia’s first single-piece rod hanger that combines:

All in one off-the-shelf product.


6. Can this C2 seismic rod hanger be used for other services?

Yes. In addition to fire hydrant systems, this rod hanger is suitable for:

  • Seismic bracing of suspended MEP services
  • Essential services in Importance Level 3 and 4 buildings
  • Retrofit and upgrade projects requiring higher compliance levels

7. Is the rod hanger compatible with ICCONS® DesignPRO?

Yes. The Thunderbolt®PRO – Galvanised Rod Hangers, is fully compatible with ICCONS DesignPRO, enabling fast and accurate anchor design and verification to AS 5216.


8. Where can I download technical data and compliance documentation?

Technical Data Sheets (TDS), fire test reports, and seismic assessment documentation are available on request. Contact an ICCONS® engineer at [email protected] for the latest information.
