Physical Security
Security Bollards, Gates & Vehicle Barriers
Langston Construction Company installs the security bollards, crash-rated vehicle barriers, and gates that lock down critical infrastructure. We set the foundations, hang the gates, place the bollards and barriers, and tie the entry point into the fence and perimeter around it.
Bollards, gates, and vehicle barriers we install
Langston handles access control installation, security gate installation, and bollard installation for utilities, data centers, and federal sites, tied into the fence and perimeter that protect critical infrastructure.
Security gates & operators
We hang swing, slide, and cantilever gates and set the operators and foundations that run them.
Bollards
We install fixed and retractable bollards that stop vehicles at entries and along the perimeter.
Crash-rated vehicle barriers
We install crash-rated barrier arms and wedge barriers rated to stop a vehicle at the M50 or M30 level, alongside crash-rated security walls built to ASTM F2656.
Guard booths & vestibules
We set guard booths, gatehouses, and access vestibules at the entry point.
Turnstiles & pedestrian gates
We install turnstiles, mantraps, and pedestrian gates that control foot traffic into secure areas.
Access-control rough-in
We set the foundations, conduit, and rough-in so the owner’s access-control hardware and readers drop straight in.
Where we stop: the card readers, credentials, and access-control software are the owner’s integrator’s scope. We build the gates, barriers, booths, and rough-in, and hold the single contract so the owner deals with one company.
Built to the crash rating and standard the job calls for
A federal entry and a substation gate are not the same. We build to the crash rating (ASTM F2656 M50 or M30), the NERC CIP-006 access requirements, and the site security plan, and we document it.

Common questions
Does Langston install the card readers and software?
No. We install the gates, barriers, booths, and rough-in. The owner’s integrator installs the readers, credentials, and access-control software.
Can you build to crash-rated M50 anti-ram?
Yes. We install crash-rated barriers and gates rated to ASTM F2656 M50 or M30, matched to the threat the security plan calls for.
Do you install bollards?
Yes. We install fixed and retractable bollards at entries and along the perimeter, on the foundations that hold them.
What is NERC CIP-006 about access?
It is the standard for controlling physical access to critical assets at a substation. We build the gates, barriers, and entry points that support it.
Where does Langston build?
From our South Carolina headquarters, for utilities, data centers, and federal and industrial sites.
