KOROK manufactures lightweight wall panels consisting of galvanised or colour steel shells filled with aerated concrete.
Generally, KOROK products are delivered to your building or other site on long trailers and articulated trucks.
Our products are packed with reasonable protection against damage during delivery, however care must be exercised during unloading.
Forklift, Hiab or crane unload is required.
GUIDELINES
Ensure packs are lifted slowly, avoiding jerking where possible.
Forklift unloading – 150mm between pack and mast.
Ensure soft slings are neatly running on the inside of the two most inner timber collars of the pack.
Ensure soft slings are running continuously from the hooks to underneath the pack and back up to the hook.
Do not loop the sling around itself with only one end connected to the hook. This may damage the panels when lifted.
Ensure you lift only one or two packs at a time.
PACK SIZES
The panels are packed in timber pallets, measuring 1200mm wide by 300mm high.
There will be 2, 4 or 6 timber pallets for each pack (depending on length), nominally spaced 1200mm apart, middled from pack centre.
Packs can be stacked up to 6 packs high and must be placed side by side or end on end, on the truck / trailer tray.
When stacking back-to-back, timber collars must butt up against each other.
The length of the pack will vary according to the length of the panel required by the customer, commonly between 2.0 and 7.0 metres in length (can be up to 9.0m).
COMMON PACK WEIGHTS
Standard 3 metre pack = 390 – 470kg (nominal); Standard 6 metre pack = 780 – 936kg (nominal).
STRAPPING DOWN PACKS
Loads must be strapped down and secured by appropriate means. Load strops are most highly recommended, allowing 12 to 16 strops for a full semi load, more for B-Train transport.
Packs are to always be strapped over timber collars. No belly straps done with plastic angles at any time.
When stacking higher than 4 packs, a second set of straps must be placed after the third pack over timber collars only, before adding further packs.
ACCESSORIES
At times, a bundle of steel C-track or Angle strips may be placed on top of the load. These may measure up to 6.0 metres in length and weigh from 10kg to 500kg depending on the quantity.
IN TRANSIT
Where possible, avoid sudden braking and jolts during transit to reduce impacts on the product.
Re-tension strops every two hours at a minimum.
UNLOADING
Forklift, Hiab or crane unload is required.
Use soft slings or forks only, no chains to be used on product.
All lifting to only be done under middle crate, closest to the bearers to take the weight.
Forklift unloading – 150mm between pack and mast.
Care must be taken on unload and storage of product, avoiding bumps and scratching.
Guidelines must be carefully followed (turn over page).
Introducing COLORSTEEL® MAXAM™: The Next Generation of Steel Solutions
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.

KOROK Panels at Work in Raglan: Quieting the Glass Recycling Hub
We’ve just wrapped up a project at the Xtreme Zero Waste recycling center in Raglan, where we installed a “box” using our fire and acoustic panels around their glass recycling facility. The goal? To keep the noise down from the glass recycling process. The crew at Xtreme Zero Waste couldn’t be happier, saying, “The box looks awesome and works well.” It’s great to see our panels doing their job, making the space quieter and more comfortable for everyone involved. We’re stoked to have been part of this project and to see our panels making a difference right here in Raglan.
In factories, warehouses and bulk retail environments, KOROK® provides strong, solid separation walls that are secure and fire compliant with high noise insulating properties.
KOROK is proud to have supplied the critical fire and acoustic wall systems for the Auckland Film Studio and Sound Stage project. Designed by Ignite Architects and built by Haydn & Rollett Construction, this facility sets a new standard in the New Zealand cinema industry.
Our 78mm KOROK panels Gen 2 were chosen for their superior fire and sound-rated properties, achieving a Noise Criterion rating below NC-20. This was crucial in ensuring optimal recording conditions, despite the studios’ proximity to urban noise sources like Auckland’s western rail line.
Sustainable Design and Construction
The project has been awarded a 4 Green Star As-Built rating, recognizing its sustainable design and construction practices.
KOROK is honoured to contribute to a project that not only pushes the boundaries of film studio design but also promotes sustainability and economic growth in Auckland. We look forward to seeing the long-term benefits this project will bring to the local community and the entertainment industry.

High-Performing and Lightweight Panels for Superior Building Solutions
The 78mm KOROK® panels are engineered to provide exceptional performance in both fire and acoustic applications. These panels are roll-formed from high-quality COLORSTEEL® steel strips, with the steel conforming to the rigorous AS/NZS1397:2001 standard.
The combination of steel shells and an aerated concrete core ensures outstanding durability and functionality. Weighing approximately 10.2kg per lineal metre, these panels offer a lightweight solution that does not compromise on strength or safety.
Key Benefits of KOROK® Panels
Fire Resistance: High fire ratings, ensuring safety and compliance with building standards.
In our commitment to innovation and sustainability, we are transitioning to the advanced COLORSTEEL® MAXAM™, replacing the previous COLORSTEEL® ENDURA® and COLORSTEEL® MAXX® ranges. This transition represents a significant technological advancement, enhancing the performance and longevity of our wall systems. COLORSTEEL® MAXAM™ is designed to offer superior resistance to New Zealand’s diverse environmental conditions, making it an ideal choice for a wide range of applications.
