More Information: Metal Roof Battens – A Lightweight, Long-Life Solution

Metal roof battens have become the preferred choice for roofing professionals and builders across Australia due to their long-lasting performance, ease of installation, and compatibility with a wide range of cladding profiles. Typically 40mm high, these battens are designed to store straight, resist warp, and outperform timber roof battens. This standard height contributes to their structural benefits, making them an economical alternative for both new builds and roof replacements.

Introduction to Roofing Systems

A well-designed roofing system is essential for any building, providing protection from the elements and ensuring the structural integrity of the structure. A crucial component of a roofing system is the roof batten, which plays a vital role in supporting various types of roofing materials, including metal and tile. Roof battens, such as timber roof battens and metal roof battens, are used to evenly distribute load stresses, including wind and weight, across the roof truss system. In this section, we will explore the importance of roof battens and their role in ensuring a strong and durable roofing system.

Why Choose Metal Over Timber Roof Battens?

Unlike timber battens that may rot, warp, or nest termites, TRUECORE® steel roof battens are built to withstand harsh Australian weather. They are lightweight, durable, and don’t absorb moisture—eliminating common timber concerns such as condensation issues and material instability. It is crucial to avoid contact between metal roof battens and certain materials, such as treated timber or copper, to prevent corrosion and ensure longevity.

These battens are compatible with metal roof systems, tiled roofs, and even wall cladding applications. Whether you’re working on carports, concrete slab homes, or truss roofing projects, switching from timber to steel battens improves performance, lifespan, and installation efficiency.

Batten Specifications & Materials

Each batten is manufactured from TRUECORE® steel and measures 40mm in height and 7.0m in length. They meet the standard roof batten spacing and strength requirements as outlined in the manufacturer’s specifications. Adhering to the manufacturer's specifications is crucial for ensuring proper installation and performance of the materials. TRUECORE® features a blue corrosion-resistant coating that makes them easy to identify and fast to install.

• Material: TRUECORE® steel

• Steel Thickness: .48 BMT

• Length: 7.0m

• Flange Design: Engineered for stability and rafter alignment

• Weight: Lightweight for faster installs and easier handling

It is recommended to use these battens in high wind areas due to their superior performance in resisting pull forces compared to softer woods.

Types of Roof Batten Systems

There are several types of roof batten systems available, each with its own unique characteristics and advantages. Timber roof battens are a traditional choice, offering a cost-effective and durable solution for many roofing applications. Metal roof battens, on the other hand, provide a strong and lightweight alternative, resistant to rot and insect damage. Other types of roof batten systems include LVL (Laminated Veneer Lumber) roof battens and steel roof battens, which offer high performance values and are suitable for various roofing applications. The choice of roof batten system depends on the specific roofing requirements, including the type of roofing material, wind loadings, and batten spacing.

Installation and Fasteners

For fixing these battens to a roof truss or rafter, we recommend using 12 x 40 screws or similar fasteners that meet the minimum fixing size standards. The required conditions and materials for installing the battens include ensuring additional fall protection and specific tie-downs, particularly in relation to structural integrity in various wind conditions. Always follow the building code and the roof manufacturer’s specifications to ensure safe and compliant installation.

Batten spacing should be calculated based on roof design and cladding type. This may vary by location, wind zone, and type of roof or cladding used.

Australian Standards and Specifications

In Australia, there are several standards and specifications that govern the manufacture and use of roof battens. These include AS 1684.2, AS 1684.3, and AS 1720.1, which provide guidelines for the design, manufacture, and installation of roof battens. Compliance with these standards is essential to ensure the structural integrity of the roof and to prevent roof failure. It is also important to consult the manufacturer’s specifications for the chosen roofing material and to review the building code requirements for the specific location, including the use of essential elements like box gutters.

Maintenance and Repair

Regular maintenance and repair are essential to ensure the longevity and performance of a roofing system. This includes inspecting the roof battens for signs of damage or deterioration, such as rot or insect damage, and replacing them as necessary. It is also important to ensure that the roof battens are properly installed, with the correct batten spacing and fastening size, to prevent roof failure. Additionally, the use of compatible materials, such as steel or timber, can help to prevent condensation and ensure a strong and durable roofing system.

Disadvantages and Limitations

While roof battens offer many advantages, there are also some disadvantages and limitations to consider. For example, timber roof battens can be prone to rot and insect damage, while metal roof battens can be noisy and may require additional insulation. Additionally, the use of roof battens can be limited by factors such as batten spacing, steel thickness, and minimum fixing size. However, with proper design, installation, and maintenance, these limitations can be overcome, and a strong and durable roofing system can be achieved. It is also worth noting that roof battens can be an economical alternative to other roofing solutions, offering a cost-effective and lightweight solution for many applications.
