Security Walls for Utilities

Power and Transmission Utility Site Upgrades Security with Precast Concrete Fencing

Two years ago, the Metcalf substation in the Bay Area of Northern California was subject to a sniper attack that caused over 15 million dollars of damage to the infrastructure. The FBI, Homeland Security and Pacific Gas and Electric investigated the security breach of the substation and it was determined to use the StoneTree® system as their preferred choice for the security wall. This year, work was completed on a 16ft high StoneTree security wall amidst other security enhancements to provide added protection to the site.

AFTEC’s StoneTree® Wall System is the only vertically cast concrete wall where the column and panel is manufactured as single wall sections and are installed using steel supports which insert into a groove in each column. This provides for a fast and safe installation process which supports and aligns each wall unit as they are being placed in the fence line. The walls are available in a variety of textured finishes which are formed on both sides.

StoneTree® Security Walls have been used on many power and transmission utility projects all around the U.S.A.

AFTEC provides turnkey service to specify, furnish and install the StoneTree® Security Wall System directly or through one of our licensed producers.

If you have a site in planning or in the process of being upgraded, contact AFTEC to determine how StoneTree® Walls can provide the security and protection to your project.
