TL4VGAN 300Engineered AestheticsThe VGAN 300 series aluminum parapet is an aesthetically designed and appealing bridge barrier system tested and accepted to NCHRP350 TL-3 and TL-4. Once erected it requires very little maintenance, providing lower whole life costs with an almost unlimited life expectancyFeatures Modular system with 3 extruded aluminum railsTransitions Transition to TL-4 Thrie-beam Cast aluminum single piece supporting posts Transition to standard 12g W-Beam Low maintenance with long life expectancy Custom transitions available Quick and easy to install 66% lighter then steel Weather-proof, corrosion-resistant & immune to UV raysMDS BARRIERSBridge Rail SystemsOptions Mesh infill optionPage 2
TL4VGAN 300DesignThe modular VGAN 300 aluminum parapet consists of 3 horizontalrail sections located to supporting posts. The system is 42” high(1070mm) 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 thatforms on the surface of the aluminum when it is exposed to air.VGAN 300 is weather-proof, corrosion-resistant and immune to theharmful effects of UV rays, ensuring optimal lifetime performance.PerformanceVGAN 300 is strong at Low Temperatures as steel becomesbrittle at low temperatures, aluminum increases in tensile strengthand retains excellent toughness.Specifications Tested and accepted to NCHRP 350 TL-3 and TL-4 Compliant with AASHTO 17th 11ContainmentLevelTestTL4 Tested on a 450mm concrete plinth Maximum system deflection is 300mm (8 Tonne Truck, impactangle of 15deg at 80km/h) Can accommodate vertical alignments of up to 2.5 degrees System weight per meter 28.10kgMDS BARRIERSBridge Rail SystemsSPECIFICATIONSStandardContainment LevelSystem HeightPost CenterPlinth AngleVehicleCarPickup TruckVehicleCarPickup TruckSingle unitVan TruckNCHRP 350TL3 and TL442” (1070mm)94.5” (2.4m)50mm minimum10-30mmPage 3
VGAN 300TL4The VGAN 300 is a remarkable system that complies with 2 standards,AASHTO 17th Edition and AASHTO LRFD. The latter requires dynamicimpact testing to NCHRP 350.The VGAN 300 was tested on a 450mm edge beam to demonstratethat the system performs on actual bridge dimensionsConstructed from aluminum the VGAN 300 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
