Are you looking for a reliable automatic sliding door supplier that won’t leave you hanging? I once managed a hotel project where the door arrived late, and no one could get a straight answer from the vendor.
That delay caused real problems, and it taught me what to avoid.
Since then, I’ve worked with engineers, project managers, and suppliers across multiple job sites. I’ve compared quotes, followed up on delays, handled returns, and tracked how each company performed during and after the sale. This list comes from those real project outcomes.
In this article, I’ll show you 8 automatic sliding door manufacturers that actually meet business needs. From quality to service, you’ll get real-world insight to help you choose smarter.
Your project deserves fewer surprises.

1. ASSA ABLOY Entrance Systems
When I first worked with ASSA ABLOY, what struck me most was how polished their process felt. From the first call to post-install checks, everything had structure. That matters when you’re under pressure to finish strong.
ASSA ABLOY Entrance Systems was established in 2006 as a division of the larger ASSA ABLOY Group, which is headquartered in Stockholm, Sweden. The group itself was formed in 1994 and has grown to operate in over 70 countries with more than 52,000 employees.
They also meet several international standards, including ISO 9001 for quality management and ISO 14001 for environmental practices. Their North American operations use AAADM-certified technicians, which keeps things code-compliant and safe. That’s a big deal when your install needs to pass inspection fast.
Popular Products

- Strong After-Sales Support Network: ASSA ABLOY offers long-term service agreements and maintenance plans through local partners.
- Smart System Compatibility: Their doors pair with digital access and security systems. You can integrate them into wider building automation with less hassle.
Final Thoughts
ASSA ABLOY Entrance Systems is best for businesses that want consistent service, global support, and a wide selection of automated entry options. But if your project is small or time-sensitive, the company’s size and longer lead times for custom requests might not work in your favor.
2. dormakaba
One of the engineers I worked with once told me, “If you want fewer headaches, choose suppliers that do more than just doors.” That stuck with me, and dormakaba is exactly that kind of company. They don’t just supply automatic doors; they build systems that combine entry, security, and control in one clean setup.
The company was formed in 2015 through the merger of two well-established names, DORMA (founded in 1908, Germany) and Kaba (founded in 1862, Switzerland). Today, dormakaba operates in over 130 countries with more than 15,000 employees worldwide.
Their headquarters is in Rümlang, Switzerland, and they hold certifications like ISO 9001, ISO 14001, and OHSAS 18001. If your business is juggling both access control and door automation, dormakaba gives you a unified solution under one supplier.
Popular Products
- Automatic Telescopic Doors: These doors offer a wider opening in compact wall spaces. They’re great for hotel lobbies or retail shops with heavy foot traffic.
- Sliding Fire Doors: Designed for emergency fire resistance, these help protect exit paths without disrupting daily use.
- Sliding Glass Partition Systems: Perfect for dividing open spaces with clear visibility. I’ve seen these used in conference rooms, restaurants, and lobbies.
- Sensor Sliding Doors: These doors use motion sensors to allow smooth entry, often used at main entrances for accessibility.
- Curved Sliding Doors: A sleek, eye-catching option often used in high-end hotels or public buildings where design matters.
Manufacturing Strength
- Integrated Access + Door Systems: dormakaba is one of the few companies offering access control, hardware, and door automation in one package. This makes integration smoother across all entry points.
- Global Engineering Teams: Their distributed R&D centers focus on region-specific compliance and innovation. This means products are tested for local building codes and user needs.
- Energy-Efficient Designs: Many of their doors meet EN16005 safety and energy use standards, helping reduce HVAC loss in busy buildings.
- High-Cycle Performance Testing: Products are tested for repeated open/close cycles, which makes them reliable in spaces with nonstop traffic like airports or hospitals.
- Strong Distributor Partnerships: Instead of doing everything in-house, they rely on trusted regional installers. That gives your team local support with global product consistency.
Final Thoughts
dormakaba is best for businesses looking to combine access control and automatic doors under one roof for a cleaner, more unified system. But if your project only needs simple sliding doors without advanced integrations, their broader focus might offer more than you really need.
3. Vallisco
Believe me when I say finding a door and window supplier that combines product variety, factory control, and project-level support isn’t easy. But Vallisco made it feel simple.
Vallisco began independent operations in 2024 under Qeeka Home, a company founded in 2007 and now based in Shanghai, China. With over 13 years of manufacturing experience behind them, Vallisco delivers commercial-grade aluminum doors and windows with a focus on quality and customization. I
I’ve noticed clients appreciate their factory-direct approach that avoids middlemen and keeps communication clear. You’ll receive technical drawings, sample confirmations, and routine delivery updates. With that kind of clarity, your project can stay on schedule and on spec.
Popular Products
- Aluminum Sliding Doors: These offer smooth glide, strong frames, and clear sightlines. Ideal for hotel lobbies, retail fronts, and villa terraces.
- Tilt‑and‑Turn Window‑Door Systems: A modern option that combines window and entry use in one unit. Great when ventilation and access need to work together.
- Sectional Garage Doors: Built for commercial bays and industrial access. Durable panels and insulation help with energy and security.
- Swing Commercial Doors: Reliable for staff entrances or smaller retail entries. They support weather sealing and low-energy operation.
- Customized Hotel Entry Sets: These doors integrate RFID access, acoustic insulation, and custom finishes to match brand standards. I’ve seen them used in boutique hotel suites and serviced apartments.
Manufacturing Strength
- Factory‑Owned Production: They manage all manufacturing in-house at their Shanghai facility. This reduces lead time and ensures consistent quality control.
- Flexible OEM/ODM Service: Vallisco accepts custom branding, finishes, hardware choices, and dimensional changes. Perfect for developers, distributors, or branded residential builds.
- Transparent Project Workflow: They offer detailed steps from consultation to sample approval to delivery. You know what’s happening at each stage.
- Strong Export Experience: With projects in Germany, Indonesia, Singapore, and Vietnam, they understand international shipping, packaging, and compliance requirements.
- Wide Product Matching to International Standards: Their doors meet CE and many European thermal, structural, and safety codes. That helps reduce compliance risk in export markets.
Final Thoughts
Vallisco is best for businesses and developers who want factory-direct delivery, flexible customization, and reliable export procedures. But if you’re looking for single-piece orders or products meant for individual home use, they focus strictly on bulk commercial supply.
4. GEZE GmbH
GEZE GmbH was founded in 1863 and is based in Leonberg, Germany. The company employs over 3,000 people and serves clients in more than 30 countries. They are certified under ISO 9001 and ISO 14001, and they’ve built a strong name in safety, automation, and intelligent building control.
I’ve found their product mix especially useful for commercial spaces that require smooth coordination between doors, ventilation, and emergency systems.
Some companies focus on just moving doors. GEZE looks at how those doors interact with air, safety, and the rest of the building. That approach matters when you’re planning spaces that do more than open and close.
Popular Products
- Sliding Glass Wall Systems: These help divide open spaces without blocking light. They’re often used in restaurants, lounges, and showrooms.
- Automatic Ventilation Windows: A smart option for natural airflow. These pair well with automatic doors in climate-controlled spaces.
- Barrier-Free Sliding Doors: Designed for accessible entries in buildings that must meet ADA or EN 16005 standards.
- Sensor-Controlled Emergency Exit Doors: These doors combine motion sensors with panic escape features. They’re commonly installed in hospitals and educational buildings.
- Integrated Door Closers with Automation: Great for areas where both manual and automatic access are needed. These are used in interior doors within office or mixed-use buildings.
Manufacturing Strength
- Vertically Integrated Production: GEZE handles everything from design to assembly in-house. This keeps their quality consistent and gives them more flexibility on custom specs.
- Modular System Design: Their doors and controls are built to work together. That makes it easier to upgrade or expand without swapping full systems.
- Building Automation Integration: GEZE systems connect to building management software using open protocols. This helps improve energy use, monitoring, and safety.
- Fire Safety Compliance: Many of their products meet fire resistance standards and are used in controlled evacuation systems.
- Training-Focused Culture: They support hands-on installer training, which improves real-world results and reduces service issues later on.
Final Thoughts
GEZE is best for commercial buildings where airflow, safety, and automation need to work as one system. But if your project is focused on a quick, standalone door install, their layered features might be more than you really need.
5. Stanley Access Technologies
If you’ve worked on projects in North America, you’ve probably come across Stanley doors. I’ve seen them installed in airports, schools, and medical centers, and they’ve always held up well under pressure. Their name carries weight when you need something tested, reliable, and code-compliant.
Stanley Access Technologies was founded in 1931 and is now part of Allegion, a global safety and access control company. Their U.S. headquarters is in Farmington, Connecticut, and they employ over 1,000 people in their door division alone. With a long history in automatic doors, they’ve built a reputation for durability, especially in high-traffic environments.
Popular Products
- Transit and Platform Doors: Used in metro stations and transit hubs, these are built to handle large crowds and constant use.
- Touchless Sliding Doors: These motion-activated doors improve hygiene and accessibility in public restrooms, hospitals, and labs.
- Healthcare Door Systems: Designed specifically for patient rooms and ICU settings, offering quiet operation and safety features.
- Manual ICU Sliding Doors: These doors provide a clear opening and optional breakout panels for emergency access.
- Retail Entrance Doors: Built with strong framing and glass options to handle storefront visibility and daily traffic demands.
Manufacturing Strength
- North American Focus: Most products are built and supported in the U.S., which means shorter lead times and fast local service.
- Legacy Parts Availability: Even older door models can still be serviced with compatible parts. That’s helpful when you’re maintaining aging facilities.
- Certified Safety Systems: They manufacture with UL-listed components and build to meet ANSI A156.10 and A156.19 standards.
- On-Site Tech Support: Their network of factory-trained field techs can troubleshoot and repair quickly, reducing downtime.
- Custom Finish Options: They offer a variety of finish and glazing combinations, which helps you match aesthetics without sacrificing performance.
Final Thoughts
Stanley Access Technologies is best for facilities that need long-term reliability, strong local support, and proven compliance with North American building codes. But if your project is international or requires highly customized smart integrations, their focus on regional markets may limit your options.
6. TORMAX
TORMAX is part of the Landert Group, a Swiss company founded in 1951. The company now operates in over 50 countries and employs more than 500 people globally. Their U.S. division is based in Texas and serves North America through a wide network of certified dealers.
When you’re working on projects that need a clean, modern look but also need parts and service to be accessible, TORMAX often checks those boxes. I’ve come across their systems in boutique hotels and office buildings, and they’ve always blended well without standing out too much.
Popular Products
- Automatic Linear Sliding Doors: These work well for commercial buildings with clean facades and straightforward access needs.
- All-Glass Sliding Doors: Designed for open views and minimalist spaces, common in showrooms and upscale retail.

- Local Dealer Model: They rely on certified regional dealers for installs and service, so your support stays close to the project.
- Quiet Operation Focus: Their systems are designed with low-noise motors, a feature appreciated in hotels, offices, and healthcare settings.
- Compact Automation Systems: Their drive units are small and discreet, making them ideal for glass-heavy or modern designs.
- Continuous Product Testing: TORMAX performs life-cycle tests under simulated real-use conditions to measure wear over time.
Final Thoughts
TORMAX is best for businesses that value design flexibility, quiet operation, and close support from trained local dealers. But if you’re handling a large multi-region project that needs centralized service and stock, their distributed model may require more coordination on your end.
7. NABCO Entrances
NABCO Entrances was founded in 1956 and is now part of NABTESCO Corporation, a global automation group based in Japan. Their U.S. operations are headquartered in Muskego, Wisconsin, and they have regional offices and authorized distributors throughout the country.
What I like about NABCO is that they don’t overcomplicate the process. They stick to what they do best, automatic pedestrian doors, and back it with standards like ISO 9001, ANSI A156.10, and AAADM-certified service. If your project values consistency and easy servicing, they’re an option that keeps things simple and solid.
Popular Products
- Sliding ICU Doors: These are used in hospitals for smooth access and patient privacy. Some models feature full breakout for emergencies.
- Low Energy Swing Doors: These provide ADA compliance without full automation, ideal for clinics, restrooms, and staff entrances.

Manufacturing Strength
- U.S.-Based Assembly: Their products are built and tested domestically, which helps shorten lead times and makes parts easier to source.
- Focus on Pedestrian Doors: Unlike some competitors with broader catalogs, NABCO concentrates its resources on refining sliding and swing door performance.
- Code-Centered Design: Many of their doors are built with ADA, NFPA, and IBC code requirements in mind, so fewer surprises come up during inspection.
- Product Line Consistency: Their long-standing models rarely change drastically, which simplifies maintenance and retrofits across properties.
- On-Demand Customization: They can adjust dimensions, glazing, and operation types within set product lines, offering flexibility without overcomplicating the order.
Final Thoughts
NABCO Entrances is best for facility managers and businesses that want no-fuss reliability, U.S.-based service, and proven performance in high-traffic zones. But if your project calls for high-end design features or global logistics, their product scope might feel a bit too focused.
8. Grupsa (GEPLAST)
Grupsa, based in Spain, has been innovating in automatic entrance systems for over 50 years. They manufacture everything in-house, which gives them tight control over quality and delivery. While they’re strong in hospital and transport projects, I’ve found them useful even in custom commercial spaces where clean design and functionality need to meet.
They’re certified under ISO 9001 and ISO 14001 and work closely with architects and engineers to meet strict hygiene and safety codes.
Popular Products
- Hermetic Sliding Doors: Commonly used in operating rooms and cleanrooms where air control is critical to performance.
- Platform Screen Doors: Designed for metro and train stations, helping improve safety and passenger flow.
- Fire-Rated Automatic Doors: These combine automation with fire protection, making them useful in healthcare and public corridors.

- Flexible Production Batches: They can handle lower-volume custom orders, which helps if your project isn’t large but still needs exact specs.
Final Thoughts
Grupsa is best for businesses handling technical spaces like hospitals, labs, or rail platforms where hygiene, safety, or controlled access is non-negotiable. But if you’re just sourcing basic commercial doors, their catalog may feel too specialized for general-purpose needs.
