BARREL VAULTS

Elevate your outdoor space with natural light and iconic curves

Barrel vaults are one of the most widely used permanent outdoor fabric structures. Their half-cylindrical form creates a smooth, curved canopy that performs well and looks refined. The design delivers strong visual appeal along with practical versatility, making it suitable for a wide range of commercial applications.

    What is a barrel vault tensile membrane structure?

    A barrel vault tensile membrane structure pairs the curved, tunnel-like form of a barrel vault with the efficiency of a tensioned fabric system. The arched geometry and lightweight membrane work together to create a durable canopy that can span large areas without internal supports.

    This open, airy design makes barrel vaults well suited to walkways, courts, courtyards, and other commercial spaces that benefit from clear, unobstructed coverage.

    Greenline is a trusted leader in the design and installation of barrel vaults. Over the last 20 years, we’ve covered more outdoor spaces than anyone else in Australia.

    Key benefits

    Barrel vaults enhance the aesthetic appeal of your space while ensuring reliable scheduling. Host events 365 days a year, rain or shine, with complete peace of mind.

    Applications in commercial projects

    The versatility of barrel vault tensile structures makes them suitable for various commercial applications. Here are some of the most common uses.

    Design and material considerations

    When designing a barrel vault structure, several factors must be considered to ensure the final product meets all project requirements. The choice of materials, for example, will impact the structure’s durability, appearance, and performance. Some options include the following.

    Barrel Vaults
    HDPE FABRIC

    Ideal for shade structures, HDPE fabric offers excellent UV protection and durability.

    PVC FABRIC

    This material blocks 100% UV rays and is completely waterproof, making it perfect for all-weather protection.

    PTFE FABRIC

    Another excellent option is PTFE fabric, which is known for its durability and resistance to environmental factors.

    Steel COLA
    AUSTRALIAN-MADE STEEL

    Australian-made steel is known for its strength and design flexibility. All our structural steel comes standard with a raw galvanised finish. For added durability and aesthetic appeal, you can opt for a powder-coated finish in custom or standard colours.

    TIMBER

    Timber is becoming increasingly popular as a design material in tensile membrane structures. It offers an alternative aesthetic for your barrel vault structure.

    Cost-effective solutions built for long-term use

    We seamlessly deliver best-in-class barrel vaults using our signature
    Consult. Design. Construct. method:

    step-1
    CONSULT

    First we start by understanding your vision and specific requirements for your Barrel Vault project. We then develop initial concepts tailored to your needs. From there, we present our recommendations, including design concepts, materials, and timelines, ensuring alignment with your goals.

    step-2
    DESIGN

    Next, we conduct site surveys and assessments to ensure feasibility. Our team creates detailed plans and 3D models, refining them with your feedback. Once finialised, we seek your approval with comprehensive documentation and cost estimates.

    step-3
    CONSTRUCT

    In the Construct phase, we finalise logistical details and coordinate with all stakeholders. Our construction team brings your Barrel Vault project to life, ensuring quality and adherence to timelines and budgets.

    Integrations to enhance functionality and user experience

    Embrace the possibilities and elevate your next commercial project to new heights. Learn more about our customisation options below.

    Lighting-Lt
    ARTIFICIAL LIGHTING

    The tensile membrane allows natural light through the day, reducing reliance on artificial lighting and keeping the space bright and comfortable.

    For evening use, we can integrate a lighting layout that suits the activity and size of the area. Our team designs systems that provide consistent, safe illumination.

    Installation-Lt
    POST PADS

    Post pads improve safety by adding a protective layer around columns. They are available in various colours to match the structure’s aesthetic.

    Each pad is custom-sized for a secure fit and a neat finish. This simple addition enhances comfort, supports compliance needs, and creates a more user-friendly space.

    Rainwater-Lt
    INTEGRATED PLUMBING

    We can incorporate eaves, gutters, and downpipes into the roof design so the structure handles water efficiently and looks visually cohesive onsite.

    Our team connects these systems to existing stormwater networks where possible. This reduces surface runoff, protects surrounding areas, and supports long-term durability.

    SportsAndRec-Lt
    SPORTING EQUIPMENT/ACCESSORIES

    We can integrate sports equipment such as basketball or netball hoops directly into the structure, eliminating unnecessary posts onsite.

    Retractable systems are available for multi-purpose areas. This keeps the space adaptable, reduces clutter, and provides safe, uninterrupted zones during non-sport use.

    AudioVisual-Lt
    PA AND AV SYSTEM

    A PA or AV system can be incorporated to support events, announcements, and presentations within your covered area throughout the year.

    Wiring and components are neatly integrated into the steelwork to keep them protected and out of sight. This creates a safer, cleaner, and more professional installation.

    GeneralPower-Lt
    GPOs

    Power outlets can be integrated into the steelwork to support equipment, events, and day-to-day use without visible cabling or potential trip hazards.

    This addition increases flexibility and convenience for users, enabling broader functionality and making the covered area more practical for a range of activities.
