Secure the Perimeter. Automate the Flow.
Industrial-grade slide, swing, and barrier gates engineered for high-cycle reliability and uncompromising perimeter security.
Not ready for a full quote? Talk to an engineer first.
ZEI installs and services industrial-grade entry gates — slide, swing, barrier, and crash-rated — engineered for high-cycle reliability and integrated with access control, LPR, and intercoms. Every install is UL 325 compliant with photo-eyes, edge sensors, and proper safety loops.
Technology Partners
A representative environment where ZEI engineers, deploys, and supports entry gates.
Where current systems fall short.
- Gates that fail repeatedly on high-cycle commercial sites
- Unsafe gate operation creating injury and damage risk
- Disconnected gates that don't share access logs or events with the rest of the system
- Slow entry creating queues at peak times
- Perimeter weaknesses where vehicles can drive through low-rated gates
The Frictionless Entrance
Control vehicle access without creating bottlenecks or compromising safety.
High-Speed Barrier Arms
Rapid-opening barrier gates designed for high-volume parking garages and toll lanes.
Heavy-Duty Slide Gates
Crash-rated and cantilever slide gates for logistics hubs, data centers, and critical infrastructure.
UL 325 Certified Safety
All installations include photo-eyes, edge sensors, and loops to prevent entrapment and vehicle damage.
Access Integration
Tie your gates to long-range RFID readers, LPR cameras, or mobile credentials for seamless entry.
What gets installed.
A real deployment is more than the headline product. These are the components we typically specify and integrate.
Gate operators
Slide, swing, and barrier operators (HySecurity, FAAC, Magnetic, LiftMaster Commercial) sized to gate weight and duty cycle.
Crash-rated gates
ASTM F2656 / DOS K-rated gates for critical infrastructure and high-threat environments.
Loop detectors
Inductive loops at exit, safety, and free-exit positions, properly cut and protected.
Photo-eyes & edge sensors
UL 325-required entrapment protection on every commercial gate.
Reader / LPR integration
Long-range RFID, mobile credential readers, and LPR cameras tied into the access platform.
Power & UPS
Conditioned power and battery backup so gates fail safely during an outage.
Telephone entry / intercom
Cellular or IP intercoms at the gate for visitor access without a guard.
Connects to what you already run.
Our entry gates integrate with your existing identity, communication, and security systems for unified operations.
How it gets built.
Every project follows the same engineering-led sequence — designed, documented, and delivered with no surprises.
- 01
Site survey
Measure gate opening, slope, soil, traffic volume, and integration with existing access systems.
- 02
Engineering
Operator and gate sizing, footing design, loop layout, and safety device plan.
- 03
Civil work
Footings, sleeves, conduits, and loop cuts coordinated with the GC or site contractor.
- 04
Gate & operator install
Gate hung, operator mounted, balanced, and aligned for clean travel under load.
- 05
Safety & access integration
Loops, photo-eyes, edges installed and tested; readers / LPR integrated; programming complete.
- 06
UL 325 acceptance
Full safety test sequence documented; staff trained on manual operation and emergency release.
What our engineers look for.
- UL 325 compliance (photo-eyes, edge sensors, secondary entrapment protection) is mandatory and verified at acceptance.
- Gate operator is sized to actual gate weight, frequency of cycles, and wind load — not "good enough."
- Crash rating (K4 / K8 / K12) is chosen against an explicit threat model, not by vague preference.
- Free-egress logic ensures vehicles can always exit on power loss, even if entry is locked.
- Maintenance access (drive belts, motor, controller) is designed for safe service without lane closure.
After the install.
Service tiers built around what your facility actually needs — not a one-size-fits-all SLA.
Annual operator service: lubrication, belt / chain tension, safety device test, and adjustment.
Semi-annual service, priority response, and inventory of common wear parts on hand.
24/7 monitoring of gate health (cycle count, motor draw, errors), 4-hour critical response, and predictive replacement of wear parts.
Gate Mechanisms
Selecting the right gate operator for your site.
Slide & Swing Gates
Maximum security for full perimeter closures.
- High security deterrence
- Crash-rated options available
- Ideal for overnight lockdown
- Requires more physical space
Barrier Arms
High-speed traffic control.
- Rapid open/close cycles
- Prevents tailgating
- Ideal for parking garages
- Lower maintenance overhead
