VGAN 400
Providing safe containment and redirection of high-energy vehicle impacts.
VGAN 400 Bridge Barrier
MASH TL4 Modular 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.
