Safety Xpress offers premium quality W-Beam guard rails designed to provide driver safety, vehicle containment and asset protection. Our w-beam guardrail system is manufactured from high-grade steel and hot dip galvanised for the ultimate in strength and durability.

Available in a plain steel finish or in high-visibility yellow, they are suitable for indoor and outdoor, on-road and off-road applications including road verges and medians, bridges and culverts, factory and warehouses and other industrial and commercial applications.

They can be used to create a safety barrier system in shared areas to ensure pedestrian safety by creating clear separation of pedestrian and vehicle spaces. They are also ideal for asset protection in spaces where machinery or infrastructure requires protection from vehicles.

The safety guard rail system is fully compliant with relevant Australian Standards and VicRoads guidelines (when properly installed) and is manufactured to quality standards on par with other industry leading brands like Armco barriers.

For the ultimate safety guard rail system, you can’t beat Safety Xpress. Besides the guard rails themselves, we can also supply all posts and base plates, end pieces, end caps, bolts and additional components that your system requires.

To find out more about the Safety Xpress guard rail system or to get help putting your order together, simply give us a call on 1300 049 246 or contact us online. One of our friendly team members will be happy to help prepare your order with everything you need to create a safe, durable and long-lasting guard rail system.

All products are available for sale online or from our physical stores in Melbourne, Sydney and the Gold Coast. We also offer fast and affordable shipping Australia wide.

FAQs

What Australian Standard governs W-Beam guard rails for road safety?

In Australia, W-Beam guard rails used in road safety applications must comply with AS/NZS 3845.1:2015, or Road Safety Barrier Systems. This standard outlines how roadside barriers should perform under impact, along with the testing, installation and manufacturing requirements that ensure consistent safety outcomes across Australian roads.

Compliance with AS/NZS 3845.1 is mandatory for public-road installations and strongly recommended for private or commercial sites looking to achieve similar levels of protection. When you buy guard rail systems for industrial or traffic use, choosing products aligned with this standard helps ensure reliable containment performance and long-term durability.

Where must W-Beam guard rails be installed according to Australian safety guidelines?

Australian road authorities, including Transport for NSW, VicRoads, Main Roads WA and Transport and Main Roads Queensland, specify when and where W-Beam guard rails are required. Common instances requiring installation include road verges, medians, bridge approaches, culverts, embankments and sharp curves where run-off-road crashes are likely.

Guard rails may also be needed where roadside hazards such as poles, drainage structures or drop-offs pose a serious risk. Outside the public-road network, guard rails are widely used in warehouses, factories, car parks and logistic yards to protect pedestrians, equipment and infrastructure.

What are the required minimum and maximum post spacing specifications for W-Beam guard rails?

Standard Australian W-Beam guard rail installations use two-metre post spacing, while one-metre spacing is common in high-impact or high-risk areas. Reduced spacing increases containment strength but may also affect dynamic deflection. Always refer to the project’s engineering specifications or state road authority guidelines before installation.

What is dynamic deflection, and why is it important when selecting a guard rail system?

Dynamic deflection refers to the horizontal movement a barrier undergoes when struck by a vehicle. Understanding this measurement is crucial because it determines how much space is required behind the rail for safe performance. If a barrier deflects into obstacles such as bridge rails, services, pedestrian paths or steep drop-offs, it could fail to protect occupants or infrastructure.

Selecting a guard rail with an appropriate deflection rating ensures the system performs correctly within the available space. In industrial environments, reduced-deflection or closer post-spacing options may be required to protect racking, machinery or walls.

What is the functional difference between galvanised and powder-coated guard rails?

Galvanised guard rails are hot-dip coated to provide exceptional corrosion resistance, making them ideal for outdoor roadsides, coastal regions and exposed industrial sites. They offer long service life with minimal maintenance. Powder-coated guard rails, commonly finished in safety yellow, are popular in warehouses, car parks and factories because they enhance visibility and help designate vehicle and pedestrian zones.

While both finishes provide strength and durability, galvanised rails excel in harsh outdoor environments, while powder-coated rails offer strong visual cues within controlled indoor settings. When comparing guard rails for sale, considering environmental exposure will help you select the most cost-effective finish.

Are crash terminals and end treatments mandatory for guard rail installations in Australia?

Yes, crash-tested terminals and compliant end treatments are mandatory for public-road installations under AS/NZS 3845.1. These components protect road users by absorbing or redirecting energy at the beginning and end of the barrier, preventing vehicle spearing or underrunning.

Common approved systems include energy-absorbing terminals, flared terminals and gating terminals, each designed to perform under specific conditions. In off-road or industrial settings, non-crash-rated end caps may be acceptable, but choosing compliant components is still recommended to maximise safety.
