What is Temporary Steel Barrier?
Typically:• Rugged• Lightweight (When compared to
concrete or water-filled barrier)• Galvanized Steel• Easy to move• Flexible applications
Examples
• Vulcan• Zoneguard• ArmorGuard• BarrierGuard 800
Physical Characteristics
• Galvanized Steel• Typically 32” Tall• Multiple Lengths – 13.5’ to 50’• Weight typically 60-70 lbs./foot• Various Connections (Pins, Bolts, Interlocking)• Very Durable• 15-20 Year Useful Life
Standards
• NCHRP 350 – TL-3 (62mph)– TL-4 (large truck)
• MASH– TL-3 (62mph)– TL-4 (large truck)
Why use Temporary Steel Barrier?
• Safety– Steel Barrier offers positive protection
• Reduce Congestion– Steel Barrier allows for dynamic lane closures – Steel Barrier allows for rapid repositioning
• Lower transport costs– 600-750 linear feet/truckload vs 120 linear feet of concrete barrier
• Speed– Deployment speeds of up 1000’/hour
• Ease of movement in the workzone• Durability
– 15-20 year useful life vs. 5-10 with concrete
Unique Features
• Wheeled Barrier– Allows for positioning
and movement by hand– Allows for towing
laterally down the work zone.
Unique Features
• Gates - Easily create openings in medians or runs of temporary barrier
Unique Features
• Movable Barrier
Applications
• Highway and road construction zones– Fixed– Changing/Moving– Short Term or Off-Peak Traffic
• Bridge Repair– Decks– Piers
• Sign – Roadside structure repair• Median or Barrier Gate Openings• Emergency Crossovers

Considerations
• Deflection– Steel barrier has less mass than concrete–Vendors have different anchoring
requirements for various workzone configurations–Deflections range from 1” to 13’.
Considerations
• End Treatments– End treatments are required where a blunt-
end hazard exists
Steel Barrier Summary
• Provides Safety for Workers• Mitigates congestion• Lightweight• Easy to move to and within the workzone• Can put 6 times as much on a truckload
compared to concrete• Saves on costs!!
