Concrete Median Road Barriers (Jersey / J-Hook / K-Rails)

Often referred to in the industry as Jersey barriers, J-Hook barriers, or K-rails, concrete median barriers offer a versatile, high-strength solution for traffic control, perimeter security, and site safety. Whether you need to channel highway traffic for a temporary construction phase or establish a permanent dividing wall, these heavy-duty precast barriers are engineered to withstand severe impacts and provide reliable protection.

Flexible, Easy-to-Deploy Design

Despite their immense weight and structural integrity, these barriers are designed with logistics in mind. They are exceptionally easy to move, place, and reposition as your project’s footprint evolves. Featuring strategic lifting points and secure interlocking systems—like the popular J-Hook connection—road crews can quickly align them to create a continuous, impenetrable wall and just as easily relocate them when the job is done.

Configured to Your Exact Specifications

Because traffic control and security needs vary drastically by location, our concrete median barriers are manufactured in a wide variety of dimensions.

• Multiple Heights: Choose from low-profile barriers for parking lots and low-speed zones, up to tall, heavy-duty Jersey profiles for maximum highway protection.

• Variable Lengths: Available in multiple lengths to efficiently cover long highway stretches or navigate tight, angled perimeters.

• Extreme Durability: Poured with high-strength concrete and reinforced to resist cracking, spalling, and environmental wear over decades of use.

Versatile Applications

Because they seamlessly transition between temporary and permanent installations, these barriers are the go-to choice for a massive range of applications:

• Temporary Work Zones: Protecting road crews and equipment during active highway construction.

• Permanent Highway Dividers: Preventing head-on collisions and dividing opposing lanes of traffic.

• Facility Security: Creating anti-ram perimeters for government buildings, military bases, and commercial facilities.

• Traffic Channeling: Managing vehicle flow in large parking lots, event spaces, and toll plazas.
