Material Aluminium Containment Level TL3 and TL4 System Height 1.070mm Post Centres 3m The VGAN 300 aluminium parapet is a modular design, consisting of 3 horizontal rail sections located to supporting posts. The system is 1070mm high and is made from special grade aluminium to meet the demands of the larger vehicle.

This remarkable system complies with 2 standards, AASHTO 17th Edition and AASHTO LRFD. The

latter requires dynamic impact testing to NCHRP 350. The VGAN 300 was tested on a 450mm edge

beam to demonstrate that the system performs on actual bridge dimensions. Constructed from

aluminium the VGAN 300 offers a high resistance to corrosion. There is no maintenance required as

with some other materials, offering a lower whole life cost, with an almost unlimited life expectancy

The design is more aesthetically appealing over conventional systems.
