Precast Concrete Panels

If you're a construction project manager or contractor in need of precast concrete panels to expedite your construction work, contact Sheds And Barns Ltd. We can safely deliver these panels to your site and also lift them into place on site via our heavy-duty cranes.

Precast Concrete Panels

Concrete Panels Building

Precast concrete panels are prefabricated concrete slabs known for their efficiency, cost-effectiveness, and high-quality construction. They are a reliable alternative to traditional timber and steel. Available in various shapes, sizes, and finishes, these panels can be used for walls, floors, roofs, and other structural components of buildings. Due to their ability to span long distances, they are ideal for manufacturing and storage structures.

We offer a variety of prestressed concrete products that builders use for projects that have a shorter completion time. These include:


  • Pre-cast Concrete Walls - These versatile panels and walls used in both residential and commercial constructions. They come in various sizes and can be tailored to match the specific needs of any project. These walls, reinforced for strength, serve multiple purposes including retaining walls and creating septic tanks as needed.
  • Precast Concrete Slabs - These multipurpose slabs are ideal for constructing elements like stairs and ceilings. The dimensions, including thickness, can be customised according to the project manager's or builder's requirements.
  • Precast Columns - The precast concrete industry offers ready-made columns to streamline the construction process. Opting for precast columns is a more convenient and efficient alternative compared to on-site concrete casting, especially for elevation requirements.

Benefits of Using Precast Concrete Slabs

Constructing with precast concrete panels offers a myriad of benefits for modern construction projects - whether you’re building barns and sheds NZ or any residential or commercial building. Known for their durability and strength, concrete panels ensure the structural integrity of buildings, offering protection against harsh weather conditions and wear. Whether used for walls, floors, or other structural elements, these panels offer superior stability and can be customised to fit specific design requirements.


These concrete slabs are made using high-quality concrete mixes for high strength and waterproofing. When curing concrete on-site, obtaining many of these materials can be challenging and they might be neglected. Hence, precast concrete exhibits considerably greater strength compared to regular concrete surfaces.

Prepared In Controlled Environment

Precast concrete is produced in controlled environments where the curing process takes place under careful supervision. In contrast, on construction sites, environmental factors such as rain, humidity, and heat cannot be controlled during the curing of concrete.

Construction Speed

One of the key advantages of precast concrete is its ability to significantly expedite the construction process for any project. Traditionally, builders had to pour concrete on-site and endure days or even weeks of waiting for it to cure.

However, with precast concrete, builders can easily order pre-made products tailored to their specifications and install them immediately. There's no waiting period required. Many reputable construction companies in New Zealand have a ready inventory of precast concrete structures to ensure a seamless and swift construction process.

Cost Saving

If you are a construction project manager or contractor, you know that time efficiency is crucial in the construction industry. Delays can lead to increased labour costs and wastage of resources. By expediting the process with precast concrete, you can significantly reduce labour costs and other expenses.

Design Flexibility

Precast concrete panels come in diverse shapes, sizes, colours, textures, and finishes to create structures with intricate decorative elements. They can also be moulded and shaped to match nearly any design or form desired. Whether you want to build large-scale industrial storage sheds or multiple storeys buildings, precast concrete panels can be your best bet.

In terms of surface treatments, various options are available:

  • Rebating and grooving
  • Surface coatings
  • Cement-based renders

For more intricate finishes, advanced techniques such as form liners, oxide colouring, and applied finishes like etching, grit-blasting, honing, polishing, and exposed aggregate can be employed.

Panel Sizes

When working with concrete panels, it's essential to optimise the panel area whenever feasible, aiming for dimensions of 20m² or larger. As a general guideline, flat lift-out beds should not exceed a total weight of 10 tonnes. The actual weight and size permissible depend on the crane's capacity and the on-site space available.

For panels transported vertically using 'A' frames, the maximum height typically ranges between 4.0m and 4.5m. The length is determined by trailer configurations and is usually capped at 12m. It's important to note that transportation restrictions are governed by state road authorities and may vary between states.

Frequently Asked Questions

How are precast concrete panels delivered to the site?

Precast concrete panels are typically delivered to the site using specialised transportation vehicles equipped with cranes. These panels are carefully loaded, transported, and unloaded using the crane equipment to ensure safe delivery.

How are precast concrete panels secured in place once they are lifted?

Precast concrete panels are secured in place using appropriate anchoring and fastening methods. These methods ensure the panels are stable, aligned correctly, and can withstand various environmental conditions.

Can precast concrete panels be customised for specific design requirements?

Yes, precast concrete panels can be customised to meet specific design requirements. This customization includes variations in surface finishes, textures, colours, and even embedded elements, allowing for a wide range of design possibilities.

Is there a limit to the height to which precast concrete panels can be installed?

The height to which precast concrete panels can be installed depends on factors such as thickness and design specifications of precast panels, and local building codes. Engineers assess these factors to determine the safe height for concrete panel installation.
