International Door

What International Door does

International Door, Inc., founded in 1936 and headquartered at 8001 Ronda Drive, Canton, Michigan, designs, manufactures, installs, and services large-scale industrial door systems for aerospace, automotive manufacturing, military, mining, and other heavy-industrial end markets. Its customer base includes Boeing (777 facility in Everett, WA; paint booth in St. Louis), NASA, Ford, General Motors, Chrysler, the U.S. Army National Guard (F.E. Warren AFB and Fort Drum aviation support facilities), Detroit Metropolitan/Wayne County International Airport, and the Collahuasi Mine in Chile. The company operates a sub-brand, the Byrne Hangar Door Division, which preserves a hangar-door specialty identity originally associated with the Byrne Door Company.

The product platform centers on motorized bottom-rolling hangar doors (including the IDI Parthenon Door, marketed as the only hoist-up fabric door 100% Made in America), vertical lift and dock doors (the flagship line, with operating speeds up to 3.5 ft/sec), canopy, crane, turnover, four-fold, sliding, blast resistant (≥100 PSF), UL-listed fire rated (up to 3 hours), and acoustical (up to STC 55) doors, plus safety edges and UL approved NEMA-rated electrical control panels (file E-145876). Supporting capabilities include a captive machine shop for custom and replacement parts across all makes and models, and factory-trained service and installation technicians with M.U.S.T. OSHA 10/30 certifications operating their own fully equipped service vehicles. Certifications include UL listings, UKAS Quality Management, and ANAB accreditation.

The business model is direct-to-customer B2B project work plus recurring maintenance: quote-based hardware sales for engineered-to-order door systems, professional installation with in-house technicians, and nationwide preventive maintenance programs and parts. The company sells exclusively through its own field sales and service organization, with no distributors or e-commerce channel, and markets through industry trade publications. The 1936 founding date and the company's stated claim that its first installed door is still operating illustrate the long product lifecycle and referenceable installed base.
