Heavy Duty Vehicle Security Barriers

Roemac Metal Fabricating has invested years of research and development to build the finest security barriers in the world. The Mac-H Vehicle Security Barrier set the standard for today's state of the art security barriers.

The Mac-H Heavy Duty Barrier is a dependable security device designed to restrict access of unauthorized vehicles to sensitive areas. Combining proven technology with innovative design, the Mac-H Barrier System has demonstrated, by actual crash tests, its ability to stop a 10-ton truck traveling at 41 miles per hour without suffering hydraulic-system damage. The barrier is located underground and will allow authorized traffic to pass without obstruction. Upon the need to physically secure the facility, the barrier can be raised to its full 36-inch height in approximately one second to present a formidable obstacle to any approaching vehicle.

The barrier is constructed of heavy structural steel members covered with non-skid steel plate, and is designed to withstand normal accidental contact by vehicles when in the raised position without suffering structural damage. When a serious attempt occurs, the Mac-H will absorb and distribute the force of impact.

Standard Features on all Barriers:

  • Energy absorbing removable barrier drum with patented rotating feature
  • Heavy steel underground holding tank, complete with drain
  • Choice of integral hydraulic system with manual lifting mechanism or remote module located separate from barrier
  • Electrical panel and push button station ready for connection to your power source
  • Heavy duty high cycle hydraulic cylinders
  • Complete instruction manual including installation, operation and maintenance
