KOROK® 78mm galv panels are precision rollformed from high-quality zinc-coated steel strips. The steel used for our shells meets the AS/NZS1397:2001 standard, ensuring consistent strength and durability. Each panel features a base metal thickness of 0.4 mm B.M.T. with a Z275 zinc coating, enclosing a lightweight aerated concrete core. This combination delivers a nominal weight of just 10.2 kg per lineal metre, making KOROK® panels easy to handle and install while maintaining exceptional structural performance.

Our panels are designed for versatility and high performance, offering superior fire and acoustic ratings for a wide range of applications. They provide fast, efficient installation with minimal on-site modifications, reducing labour costs and program delays. The lightweight nature of KOROK® panels also eases transport and handling, particularly on multi-storey construction projects.

Backed by over 20 years of experience, KOROK® panels are BRANZ-appraised, Kiwi-owned, and widely trusted across New Zealand for projects ranging from residential developments to complex commercial constructions. Our systems are designed to simplify installation, maximise safety, and deliver long-lasting performance, making KOROK® the preferred choice for builders, architects, and developers seeking reliable fire and acoustic wall solutions.

51mm KOROK® panels are rollformed from zinc coated steel strips. The steel from which the shells are manufactured conforms to AS/NZS1397:2001. Steel shells have a base metal thickness of 0.4mm B.M.T. with a Z275 zinc coating. These panels have an aerated concrete core and weigh nominally 10.2kg per lineal metre.

KOROK® produces 51mm panel. KOROK® 51mm panel provides a -/60/60 FRR and is perfectly suited for terraced house intertenancy walls and apartment intertenancy walls.  The narrower gauge allows you to keep more floor space as it isn’t taken up by walls.

Performance and Features

• Fire Rating: KOROK® 51mm panels provide a fire resistance rating of -/60/60 FRR, meeting stringent safety requirements for intertenancy walls in terraced houses and apartments.
• Acoustic Efficiency: Designed to reduce sound transmission, these panels ensure quieter living environments, making them an excellent choice for densely populated or high-traffic areas.
• Space-Saving Design: The 51mm thickness allows for slimmer walls, helping to maximize valuable floor space without compromising structural integrity or performance.

KOROK® 51mm Galv panels are used for:

• KOROK® Intertenancy Terraced Housing Wall Systems
• KOROK® Intertenancy Apartment Wall Systems

Applications and Systems
