About GDI

Engineering reliability in garage door and gate operator systems for over 20 years across North America.

Our Mission

To relentlessly engineer and deliver the most dependable, high-performance operator systems in the industry. We leverage decades of proprietary technology—including Algorithm™ Drive, Compact GearMotor™, NetworkPower™ communications, and SmartCharging™ battery backup—to ensure every door and gate operates with precision, safety, and efficiency.

Through collaborative development with installers, technicians, and facility managers, we tailor solutions that thrive in the harshest climates and highest-cycle environments. From concept to commissioning, GDI is committed to excellence in design, manufacturing, and service, delivering robust automation that keeps businesses running smoothly.

Our Vision

To lead the evolution of door and gate automation by setting the standard in reliability, intelligence, and sustainability. We envision a future where every facility—from warehouses and dealerships to hospitals and retail centers—benefits from real-time diagnostics, seamless connectivity, and energy-efficient operation.

As pioneers of smart automation, we aim to expand our global footprint, foster industry partnerships, and continuously innovate our integrated solutions to meet the challenges of tomorrow’s connected world.

Core Technologies & Advantages

Algorithm™ Drive

Proprietary motor-controller algorithms developed since 1993 deliver precise torque control, higher efficiencies, and more power in a compact package.

Compact GearMotor™

Lightweight, fast to install, servo-precision positioning—and high power density for tight spaces.

NetworkPower™

Integrated communications for remote monitoring, diagnostics, and can be controlled over Wi-Fi or Ethernet.

Obstruction Sensing

Fully electronic, current-based sensing detects any jam or obstruction—no mechanical adjustments required.

Battery Backup

SmartCharging™ control plus high-efficiency motors enable 50–200 uninterrupted cycles on battery power during outages.

Full Motion Control™

Profile-based soft-start/stop and field-adjustable acceleration/deceleration for smooth, repeatable door movement.

Proven Durability & Performance

Thousands of GDI operators perform millions of cycles in environments from –30 °C freezers to tropical humidity and corrosive washdown settings.

A longtime customer reported an operator exceeding 2 million cycles without unscheduled service—testament to our marine-grade aluminum housings, nitrided steel shafts, double planetary gears, and premium North American grease.

Our Operator Models

Our lineup of five specialized models meets every commercial and industrial door or gate requirement—simplifying selection, installation, and support.

JHMG

Our highest-cycle rated operator—engineered for 10,000+ cycles per day in the most demanding industrial settings. Ideal for cold storage, high-speed rollups, and vertical lift systems, it combines a compact GearMotor™ with planetary gears and advanced smart controls for unmatched endurance and reliability.

JDMG

The most versatile operator in our lineup, compatible with nearly every door type including low-headroom, rolling steel, and fabric roll-ups. Combines jackshaft and trolley configurations in one modular system with high-efficiency planetary gearing and watertight options.

HAML

Our most compact, sealed operator—HAML is a high-cycle, direct-drive GearMotor™ engineered for tight spaces and harsh conditions. With a fully enclosed, washdown-safe design, it excels in car washes, luxury showrooms, and high-particulate environments where other systems fail.

Gate Models

GLWD

High-speed barrier gate operators designed for parking lot entrances and traffic control. Features integrated crowd-management logic, emergency egress release, and rapid open/close cycles to keep vehicles moving smoothly.

SGWD

Robust sliding gate automation engineered for residential and commercial sliding gates. Offers precise drive control, heavy-duty drive assemblies, weather-tight housings, and safety features like obstruction sensing and auto-close timers.
