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

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 bluntend 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!!
