VGAN Bridge Barrier
VGAN 400 is a MASH TL4 compliant, modular barrier designed for installation along the edges of bridges and elevated concrete structures. Featuring a triple rail design, VGAN 400 is manufactured from lightweight, special grade aluminium providing safe containment and redirection of high-energy vehicle impacts. The modular design uses standard components facilitating rapid installation and ease of repair. The single-cast posts are secured to cast-in anchors for new bridge constructions or can be secured to existing decks with chemical anchors.

Frequently Asked Questions
What are the features of VGAN 400?
The VGAN 400 aluminium parapet is a modular, three-rail design supported by robust supporting posts at 1.83 m centres. The height of the system is 1200 mm.
What is the containment level of VGAN 400?
VGAN 400 has been crash tested in accordance with MASH Test Level 4 (TL4).
What is the MASH TL4 impact performance of VGAN 400?
The maximum dynamic deflection of VGAN 400 during MASH TL4 crash testing was 0.5 m. The working width of VGAN 400 during MASH TL3 crash testing was 1.16 m. These results were recorded during an impact with a 10,000 kg rigid truck travelling at 90 km/h and 15 degrees.
How are the VGAN posts manufactured?
The VGAN supporting posts are a single cast aluminium alloy.
What anchor fixing options are available?
The posts may be fixed using cast-in ferrules or drilled chemical anchors.
What are the durability benefits of aluminium?
Aluminium forms a thin, self-healing oxide layer that immediately reforms if scratched. This passive layer is chemically stable in most environments, including coastal and industrial atmospheres.
Can a cycle rail be used with VGAN 400?
Yes. Customised options are available.
What is the recommended minimum plinth dimensions?
The minimum sizing of the concrete plinth shall be 440 mm wide x 230mm high.
What is the recommended minimum installation length?
The minimum recommended length of VGAN 400 to achieve MASH TL4 containment is 30 m.
Can VGAN 400 connect to thrie-beam guardrail?
Yes. VGAN 400 can be fabricated with a connection plate for direct connection of the thrie-beam terminal connector. An appropriate transition should be installed when connecting to a guardrail barrier to gradually increase the stiffness of the system and reduce the potential for vehicle pocketing.
