TL4VGAH 2000DesignThe modular VGAH 2000 aluminum parapet consists of 4 horizontalrail sections located to supporting posts. The system is 54” high(1.370m) and is made from special grade aluminum to meetthe demands of the larger vehicle impacts.MaterialManufactured entirely of aluminum which has an excellent resistance to corrosion due to the thin layer of aluminum oxide that formson the surface of the aluminum when it is exposed to air. VGAH2000 is weather-proof, corrosion-resistant and immune to theharmful effects of UV rays, ensuring optimal lifetime performance.TL4 CRASH TESTPerformanceSpecificationsVGAH 2000 is strong at Low Temperatures as steel becomesbrittle at low temperatures, aluminum increases in tensile strengthand retains excellent toughness.Specifications Tested and NCHRP 350 TL-4 and MASH Compliant with AASHTO 17th Edition Tested on a 450mm concrete plinth Can accommodate vertical alignments of up to 2.5 degreesSPECIFICATIONSStandardContainment LevelAASHTO 17th EditionSystem HeightPost CenterPlinth HeightNCHRP 350TL4 / H2 W3MASH TL4 80kps54” (1.370m)8.202ft (2.5m)50mm minimum System weight per meter 32.56 lbs /ft.

VGAN 2000TL4The VGAH 2000 is a remarkable system that complies with MASHAASHTO 17th Edition and EN1317 Classification H2 W3.The VGAH 2000 was tested on a 450mm edge beam to demonstratethat the system performs on actual bridge dimensionsConstructed from aluminum the VGAH 2000 offers a high resistanceto corrosion. There is no maintenance required as with some othermaterials, offering a lower whole life cost, with an almost unlimited lifeexpectancyThe design is more aesthetically appealing over conventionalsystemsAASHTO 17th EditionThe AASHTO 17th Edition specification does not require parapets tobe dynamically tested; instead their performance is determined bycalculation.MDS BARRIERSBridge Rail SystemsPage 4
