What Are Deflection Head Details?

Deflection head details are specialized components used in wall and partition systems to accommodate vertical or horizontal movement in a building’s structure. They are typically placed at the top of walls, allowing the structure to expand, contract, or shift without compromising the wall’s integrity or performance.

This movement can be caused by various factors, such as dead loads, live loads, thermal expansion, or seismic activity. At KOROK Building Systems, our deflection head solutions are designed to provide the flexibility and stability needed in high-performance wall systems.

KOROK deflection head details:

• Maintain Structural Integrity: Designed to allow movement in walls without damaging the structure, these details help prevent cracking or separation in response to building movement.
• Ensure Fire and Acoustic Performance: KOROK deflection heads are rigorously tested to retain fire resistance and acoustic ratings, even with movement, maintaining protection in all conditions.
• Seismic Readiness: In New Zealand, where seismic activity can impact building structures, our deflection head designs are engineered to absorb and adjust to seismic forces, supporting safe and resilient structures.

Dead and live loads can cause significant deflection in some structures. KOROK® can provide deflection C-track details where deflection loadings are considered.

Whether used in commercial or residential projects, KOROK’s deflection head details meet the highest industry standards, offering a reliable solution for builders, architects, and contractors who prioritize safety, performance, and durability.

At KOROK, we are committed to delivering the highest quality fire and acoustic rated wall systems, and today we are excited to introduce a major upgrade in our materials. We are transitioning to the new COLORSTEEL® MAXAM™, which will replace our previously used COLORSTEEL® ENDURA® and COLORSTEEL® MAXX® ranges. This change marks a significant advancement in the technology and performance of our wall systems.

What is COLORSTEEL® MAXAM™?

COLORSTEEL® MAXAM™ combines the renowned quality and consistency of COLORSTEEL® with innovative ACTIVATE™ technology. This new single substrate product solution is designed with corrosion resistance and longevity in mind, making it suitable for most of New Zealand’s environmental conditions.

The Benefits of ACTIVATE™ Technology

• Strategic Positioning: The aluminium/zinc/magnesium compounds in the coating are strategically positioned to activate at the start of weathering, providing sacrificial protection when it is most needed.
• Robust Barrier Formation: Magnesium compounds encourage the formation of a robust barrier at cuts and scratches, slowing the rate of subsequent corrosion.
• Long-Lasting Protection: The magnesium compounds ‘activate’ the metal coating, resulting in more effective, longer-lasting sacrificial protection.

Transitioning to the Future

The introduction of COLORSTEEL® MAXAM™ reflects our commitment to innovation and excellence. By integrating this advanced material into our KOROK wall systems, we are ensuring that our products not only meet but exceed the highest standards of performance and durability. For more information on COLORSTEEL® MAXAM™ and its benefits, please contact our customer service team.

High‑Performance Fire and Acoustic Wall Systems

KOROK® provides a full range of engineered fire and acoustic wall systems designed for New Zealand’s residential, commercial, and industrial buildings. Our systems are rigorously tested, easy to install, and built to meet the latest compliance requirements. Explore our solutions for intertenancy walls, external façades, cinemas, industrial spaces, lift shafts, risers, ducts, and scissor stair applications.

KOROK® has 2-way fire-rated wall systems for fire separation of Scissor Stairs or any Stairs.

KOROK® Scissor Stair Systems are proprietary, non-loadbearing, two-way fire-rated wall systems designed to provide fire and acoustic separation between independent stair flights within scissor stair configurations or other stair arrangements.

The system utilises 78mm thick interlocking KOROK® panels installed between two independent stair stringers to form a continuous fire-resisting barrier. Panels may be oriented vertically, horizontally, or in combination to suit stair geometry and construction sequencing requirements.

The system is BRANZ tested and Warringtonfire assessed, and is intended to meet or exceed the performance requirements of the New Zealand Building Code (NZBC) and NCC Australia within the defined scope.

How the System Works

KOROK® Scissor Stair Systems are constructed using 78mm thick panels comprising roll-formed galvanised or colour steel outer shells with an aerated concrete core and interlocking tongue-and-groove profiles, forming a continuous, tightly sealed wall plane that reduces the risk of acoustic leakage between stair flights. The system is non-combustible and provides two-way fire resistance when exposed from either side. In fire conditions:

• Horizontal fire resistance is achieved through a quadrilateral fire-resistant section formed between the two independent stairs
• Vertical fire resistance is achieved through the wall-to-stair stringer boundary condition

KOROK® Scissor Stair Systems provide independently tested Fire Resistance Ratings up to –/120/120 and –/60/60 depending on configuration, while the 78mm interlocking panels deliver acoustic performance up to STC 76, meeting or exceeding NZBC Clause G6 requirements through their aerated concrete core and tightly sealed joint geometry.
