The system is 1070mmhigh and is made from special grade aluminium to meet the demands of thelarger 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.
