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.
