Expanded Metal Fencing

Extreme Strength Deters Attack

Simply hold a piece of chain link fencing in one hand and expanded metal in the other. There is no comparison. The metal fence will not bend. This style of our high security fence is rigid and solid with no welds that will weaken or twists that can come undone.

Anti-Cut Fence Denies Access

Take a pair of bolt cutters to chain link fence wire, then try the same with expanded metal. The chain link fencing will cut easily and then begin to unravel. This high security fence option is resistant to being cut. It is likely the bolt cutters will not even grab enough metal to get through the expanded metal fence.

Anti-Climb Fence Panels Delay Intruders

The smaller mesh, or opening size of the diamonds, the more difficult a fence is to climb. Most standard chain link fence wire measures approximately 2" across. Compare that with a 1/2" or 3/4" measurement on expanded metal. These high security, no-climb fence panels provide no way to get a toehold for climbing or even a strong finger hold.

Complete the Expanded Metal Fencing with Super-C Framework

Gregory Fence's Super-C framework, as specified by ASTM F1043, provides greater strength than Sch. 40 pipe. It is coated with a minimum of 2 oz. of zinc per square foot (the heaviest coating on the market). This provides greater corrosion protection than any tubular pipe. All at a lower cost!

Expanded Metal vs. Chain Link

Expanded mesh provides a high-security fence alternative to chain link thanks to its tight mesh construction, making it ideal for applications that require the strongest perimeter protection.

C-Post Framework for High Security Fence Systems

Expanded metal fence systems are widely specified for greater strength and corrosion protection. Gregory expanded metal fence panels are supported by the Gregory C-Post steel framework, which provides greater structural strength and corrosion resistance than traditional pipe post systems.

Stronger Expanded Metal Fence Systems with C-Post

The Gregory C channel fence post is stronger, quicker to install and more resistant to corrosion over time. This fence framework depends on the more effective C-shape metal fence posts, which offer greater bending strength perpendicular to the fence line. Gregory C-Post fence benefits include:

• Can be mechanically driven without the use of concrete
• Heaviest amount of continuously coated zinc available on any framework on the market
• Open-channel design eliminates condensation buildup inside, reducing maintenance
• Drives quicker, easier and self-anchors more effectively than tubular posts
• Available in any length

When combined with expanded metal fence panels, the C-Post framework creates a durable high-security fencing system designed for critical infrastructure and perimeter protection.

FAQ

Below are some of the most frequently asked questions about Gregory Expanded Metal Fence panels.

What is expanded metal fencing?

Expanded metal fencing is a high security barrier system that utilizes perforated and formed steel panels instead of chain link or other panel types.

Is expanded metal fencing stronger than chain link?

Yes. Compared to chain link or welded wire fence systems, expanded metal fencing contains no welds and offers a continuous barrier that significantly deters intruders.

Why are expanded metal fence panels used for high-security fencing?

Expanded metal fence panels provide superior protection in high-security applications because their rigid steel mesh construction offers greater strength than chain link or wire welds and resists cutting, climbing or deformation.  

Where is expanded metal fencing typically used?

Expanded metal fence systems are ideal for applications that require increased perimeter security, such as airports, correctional facilities, utilities, and critical infrastructure.

Can expanded metal fence panels be installed on chain link fence framework?

For the greatest security, install expanded metal fence panels on Gregory C-Post framework. C-Post offers superior strength and corrosion resistance compared to standard pipe posts.
