Panel Handling

Panel Handling

Panel Handling

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.

Panel Handling

Forklift unloading – 150mm between pack and mast.

Panel Handling

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.

Panel Handling

Do not loop the sling around itself with only one end connected to the hook. This may damage the panels when lifted.

Panel Handling

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).

Deflection Head Details

Deflection Head Details

Deflection Head Details

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.

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

 

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.
Deflection Head Details

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.

Sustainability

At KOROK, we aim to balance industry and nature. We’re committed to providing high-performance products with a minimised environmental impact.

Our Commitment to Waste Reduction

At KOROK, we focus on reducing waste and being environmentally responsible. Our efficient manufacturing processes and thoughtful product designs help us provide reliable, high-performance solutions.

KOROK’s Sustainability Journey

Reducing Waste

Made to Order

Our panels are manufactured to order, ensuring minimal waste. This custom approach means minimal off-cuts and no unnecessary waste, as each panel is designed to fit specific job requirements perfectly.

Fully Reusable

KOROK panels are designed for reuse. They can be taken down and reassembled multiple times, making them ideal for reconfiguring warehouse or retail spaces. This reusability significantly enhances their ecological friendliness, reducing the need for new materials and minimising waste.

Fully Recyclable

When a KOROK panel reaches the end of its life cycle, it doesn’t need to end up in a landfill. The panels can be disassembled for recycling: the concrete core is crushed and repurposed, and the steel casing is recycled. This closed-loop process ensures that our products contribute to a sustainable future.

Environmental Product Declarations (EPDs)

We are proud to announce the completion of our Environmental Product Declarations (EPDs), a testament to our commitment to transparency and sustainability. One for our Galv panel and one for our Colour panel.

What is an EPD?

An Environmental Product Declaration (EPD) is a certified, independently verified summary of a product’s environmental impact over its entire life cycle. It evaluates:

  • The materials extracted from the earth.
  • Energy used in the production, transportation and installation.
  • The environmental impacts of using, disposing, or recycling the product.

The EPD covers a range of environmental indicators, including the potential for carbon emissions, air and water pollution, and depletion of natural resources. Based on international standards (ISO 14025 and EN 15804 for building materials), our EPD is independently verified, making it a trusted and reputable source of information. It is recognized by industries, companies, and governments, and is often specified in tender documents and contracts.

KOROK’s Sustainability Journey

Officially Recognised

A DECLARE LABEL ANSWERS THREE QUESTIONS:

  1. Where does a product come from?
  2. What is it made of?
  3. Where does it go at the end of its life?

Declare is a transparency platform and product database that is changing the materials marketplace.
