Sliding and folding automatic doors move high volumes of people through an entrance smoothly, quietly, and hands-free, while making the most of the space you have. Piedmont Door Solutions designs, installs, services, and repairs commercial automatic sliding and folding doors across the Southeast, Southwest, and Mid-Atlantic. Because we represent many of the most iconic brands in the industry, we help you specify the right system for your traffic, your opening, and your budget, then keep it running with certified service. Our technicians are certified by the American Association of Automatic Door Manufacturers (AAADM) to install, service, and perform the code-compliance and life-safety inspections your facility relies on.

Automatic Sliding Doors

Automatic sliding doors are the workhorse of high-traffic commercial entrances. The panels slide horizontally out of the walking path, so they move steady two-way traffic quickly and seal tightly when closed for better energy efficiency. They come in single-slide, bi-parting, and telescoping configurations, plus all-glass options for a clean architectural look, and heavy-duty and hurricane-rated builds for demanding sites.

We install, service, and repair sliding operators and activation from:

  • Stanley Access Technologies (Dura-Glide 2000/3000, Dura-Storm hurricane-rated, Dura-Guard industrial)
  • Horton Automatics (2000 Linear Drive, 2000B Belt Drive)
  • NABCO / GyroTech (GT1175 Whisper Slider, GT8710)
  • ASSA ABLOY Entrance Systems / Besam (SL500 single, bi-parting, and telescopic)
  • dormakaba (ES200 / ES250)
  • RECORD and Hunter / Ditec Entrematic sliding operators
  • Activation and safety: BEA and Optex sensors, and integrated access control

Best for main building entrances, retail and grocery storefronts, hospital and clinic entrances, airports, and any high-traffic opening where fast, reliable, two-way flow matters.

Automatic Folding Doors

Automatic folding doors solve a specific problem: getting the widest possible clear opening in a space too narrow for a sliding or swing door. The panels fold to the side rather than sliding straight back, so you gain usable opening width without the wall pocket a slider needs. That makes them ideal for narrow vestibules, tight corridors, and retrofit openings where every inch counts, and they include emergency breakout for safe egress.

Folding systems are a specialized product, and we install, service, and repair the major brands:

  • Gildor (bi-folding automatic entrances)
  • Horton Automatics (FoldingAccess, fold-in and fold-out configurations for corridors and vestibules)
  • NABCO / GyroTech (GT1400 folding door)
  • Stanley Access Technologies folding door systems

Best for narrow vestibules, hospital and facility corridors, and any opening where you need maximum clear width in minimal space.

Where Sliding and Folding Doors Make Sense

We install and maintain automatic sliding and folding doors for facilities where smooth, accessible, hands-free entry is part of doing the job right:

  • Healthcare and medical facilities: clean, hands-free access at main entrances, vestibules, and corridors that supports a good patient and staff experience and keeps you survey-ready as a matter of good operations practice.
  • Retail and grocery: welcoming, high-throughput storefront entrances.
  • Airports and transit: fast, reliable flow for constant two-way traffic.
  • Offices and corporate campuses: lobby and vestibule entrances with a clean architectural look.
  • Schools and universities: accessible main entrances and high-traffic openings.
  • Senior living and assisted living: effortless, accessible access for residents and visitors.
  • Narrow or retrofit openings: folding systems where a slider or swing simply will not fit.

Automatic Sliding & Folding Door FAQs

What's the difference between an automatic sliding door and a folding door?
A sliding door's panels slide straight back along a track, which is ideal for high-traffic entrances with room for the panels to travel. A folding door's panels fold to the side, giving you the widest possible clear opening in a narrow space where a slider or swing door won't fit.
Which is better for a busy main entrance?
For steady two-way traffic, a sliding door is usually the best choice. Bi-parting sliders move the most people quickly and seal tightly when closed for better energy efficiency.
Can a folding door work where a sliding door won't fit?
Yes. That's exactly what folding doors are for. Because the panels fold rather than slide into a wall pocket, they deliver a wide clear opening in tight vestibules, corridors, and retrofit openings.
Which sliding and folding door brands do you service?
We install and service the major brands including Stanley, Horton, NABCO/GyroTech, RECORD, ASSA ABLOY/Besam, dormakaba, Hunter/Ditec, and Gildor for folding, plus BEA and Optex activation and sensors.
Do sliding and folding doors need annual inspections?
Yes. AAADM recommends an annual safety inspection, and our AAADM-certified technicians perform code-compliance and life-safety inspections on every major brand.
