A Legacy of Innovation in Fire Safety & Security

Since 1962, Won-Door has set the standard for fire-rated horizontal sliding door systems. From pioneering the world's most durable acoustically-rated folding partitions to launching the first accordion-type, fire-rated horizontal sliding door in 1977, they have consistently advanced both fire protection and modern access control. Won-Door technologies are evaluated by ICC-ES (ESR-1394), comply with the NFPA 80 standard and NFPA 101 Life Safety Code, meet International Building Code requirements, and are trusted by organizations focused on life safety and threat management worldwide.


Comprehensive Fire Door Solutions

We offer a wide range of fire and security products and services:

  • Accordion fire doors
  • Commercial fire doors
  • Fire door swing operators
  • Corridor doors and smoke door assemblies

Every fire door assembly is engineered to meet stringent fire resistance requirements and pass rigorous hose stream and forced-entry tests, ensuring your occupants are prepared for fire emergencies and security threats alike. Won-Door fire rated doors can also reduce fire sprinkler system requirements in atriums and elevator lobbies — lowering overall project cost while maintaining full opening protective compliance.


The Dual Promise: Security & Fire Protection

Won-Door's SteelGuard® sets a new standard by combining robust security with proven fire safety performance. You don't need to choose between protecting against intrusion and meeting fire code. SteelGuard® delivers both.

Engineered to deter forced entry and respond to threats without slowing daily operations. The rugged steel construction and flexible deployment options make it an ideal choice for facilities where security matters as much as safety. Compartmentalize and harden a building in seconds — at the push of a button — while still meeting ADA requirements and allowing safe egress for all occupants.

Reliable Fire & Smoke Containment

SteelGuard® doors provide code-compliant barriers that meet strict fire and life safety requirements, automatically compartmentalizing smoke and fire in emergencies to buy critical time for evacuation and response. Fire resistance ratings up to 3 hours, tested to UL 10B standard.

Where You Need It: Applications

Won-Door solutions are built for today's commercial properties, adapting to a wide range of operational demands.

You'll find Won-Door protecting:

  • Commercial Offices: Secure lobbies, corridors, and restricted areas while maintaining open aesthetics and easy access for staff and visitors. Amazon HQ, Comcast Headquarters, and Chevron use Won-Door throughout their campuses.
  • Education: Compartmentalize classrooms, hallways, and entry points to improve both daily security and emergency response. Won-Door is installed in over 1,600 universities and tens of thousands of K-12 facilities — including schools that use push-button lockdown to protect students.
  • Healthcare Facilities: Manage sensitive areas and patient flow, all while supporting strict fire safety, infection control, and security protocols. Johns Hopkins, Mayo Clinic, and the Children's Hospital of Philadelphia all rely on Won-Door.
  • Government & Public Spaces: Maintain reliability and flexibility in courthouses, civic centers, and transit hubs. The Pentagon currently operates over 150 Won-Doors following their proven performance on September 11, 2001.
  • Retail & Mixed-Use: Protect storefronts, service corridors, and staff-only zones without disrupting business or design.
  • Stadiums & Large Venues: Mercedes-Benz Stadium, Globe Life Field, and Boston Garden all use Won-Door systems — with openings large enough for trucks and equipment to pass through.

Won-Door systems integrate with your fire and security infrastructure, so you can compartmentalize, lock down, or open up as needed — keeping people safe and operations running smoothly.


How It Works: Simple, Reliable Integration

Won-Door systems are designed for straightforward operation and dependable performance. Each door can be configured to work with your existing security and fire alarm systems, allowing for coordinated responses to any situation — a routine closing, an emergency lockdown, or a fire event.

Daily use is easy for your staff: Won-Door products move smoothly and require regular maintenance to ensure proper operation and code compliance. For facility managers and building owners, that means scheduled fire door inspection visits, closing mechanism checks, and clear documentation — not emergency calls at the wrong moment. When it matters most, automatic deployment secures and compartmentalizes areas quickly — buying time and protecting people.

Ongoing support is always available from , so your doors keep working just as intended. Whether it's regular inspection, fire door repair, or answering your team's questions, you have a partner invested in your building's safety and compliance.



Frequently Asked Questions

FireGuard™ is a horizontally sliding fire door assembly, not a swinging door. It's the only horizontal sliding opening protective approved for use in a means of egress with no occupant load restrictions — meaning it can replace banks of swinging doors in corridors, stairwells, and large openings while maintaining full NFPA 80 compliance. It also spans openings that swinging doors can't, from standard corridor widths to custom configurations over 200 feet long.

Won-Door FireGuard™ systems carry fire protection ratings up to 3 hours, tested to UL 10B standard — a fire test that includes both flame exposure and hose stream requirements. Won-Door also manufactures the only Movable Fire Wall tested to the ASTM E119 standard. All fire rated door assemblies are evaluated by ICC-ES (ESR-1394) and compliant with NFPA 80 requirements for fire resistance, smoke and draft control, and access control.

Yes. Won-Door systems connect to new or existing credentialed devices and monitoring systems — keypads, card readers, fingerprint scanners, and building security controls. SteelGuard® and FireGuard™ can be configured to compartmentalize a building in seconds at the push of a button, prohibiting entry while still allowing emergency egress.

Both. Won-Door is regularly specified for retrofits — replacing aging or inadequate fire door systems in existing buildings. Door Services Corporation can assess your existing openings and specify the right Won-Door product for the application.

Door Services Corporation provides ongoing fire door maintenance, inspection, repair, and compliance documentation for all Won-Door systems we install — and for existing installations that need a service partner. After installation, we commission every door to verify proper operation before it goes into service. Our AAADM-certified fire door inspectors check door hardware, smoke seals, closing mechanisms, and compliance against current fire safety regulations. We're available 24/7 for emergencies and can set up a Preventive Maintenance Agreement (PMA) to keep your system inspection-ready year round.
