What Crown Doors does
Crown Doors, LLC is a US-based custom manufacturer of patented hydraulic and electrically actuated architectural door and window systems, founded in 1997 and operating from a single headquarters and production facility at 135 McLeod Avenue South in Plato, Minnesota. The company's product line consists of six core systems—SST-II Hydraulic Bi-Fold, Electric Bi-Fold, Hydraulic Single Swing, Electric Single Swing, Hydraulic 50/50, and Hydraulic Vertical Lift—built entirely from steel with in-house powder coat finishing. Its underlying technology replaces the cables, straps, pulleys, springs, and locking mechanisms used by conventional automated doors with hydraulic cylinders (delivering 1,000+ lbs. of closing force) or self-contained electric actuators, enabling floor-free openings, vertically folding or lifting panels, and perimeter seals without auxiliary motors or power units. Two US patents (8,714,229 and 9,567,789) protect the core actuation architecture across the bi-fold and 50/50 platforms.
The company sells directly to end customers via phone (320-238-2616) and email ([email protected]), targeting architects and designers (who receive BIM Revit families and CAD details), specialty contractors working on luxury residential and commercial projects, and homeowners. Pricing is quote-based and project-specific, with each system manufactured to custom dimensions, finishes (including full RAL color catalogue), glazing, and cladding specifications such as clear-anodized aluminum curtain wall, wood, bar grate, and raw steel natural patina. Revenue is generated through one-time custom system sales with no disclosed recurring service, subscription, or licensing component.
Customer concentration is dispersed across more than 30 named enterprise, government, and education installations, including Target Field (Minnesota Twins), Allianz Soccer Field, Sierra Nevada Brewery, BMW/Rolls Royce Irvine, Mercedes-Benz of Sacramento, Gensler Offices, Sonos HQ, Atlanta United training ground, Yeti Austin, Mystic Lake Casino Hotel, Ford Calumet Environmental Center, and Butler County Community College. Hufcor Minnesota serves as an installation partner for stadium projects. The company is privately held with no parent, no external funding rounds, no subsidiaries, and no disclosed management team beyond a general contact channel.

The company sells directly to architects, contractors, and end owners across commercial and luxury residential applications, and operates an in-house powder coat finishing service to support customization. Each system is custom-engineered with all-steel construction and perimeter sealing, and is delivered pre-hung for simplified installation.

Crown Doors offers a portfolio of patented, hydraulically and electrically actuated architectural automated door and window systems. The product line consists of six core systems: the SST-II Hydraulic Bi-Fold System and Electric Bi-Fold System (vertically folding doors), the Hydraulic Single Swing System and Electric Single Swing System (outward swinging panels), the Hydraulic 50/50 System (combining bi-fold and single swing features), and the Hydraulic Vertical Lift System (straight-up elevation).

Products and services
- SST-II Hydraulic Bi-Fold System Patented hydraulically operated bi-folding door and window system that opens vertically, allowing smooth, quiet access between environments. Uses hydraulic cylinders in place of cables, straps, locking mechanisms, pulleys, and springs, with 1,000+ lbs. of closing force creating a tight perimeter seal. Targets commercial and luxury residential projects that need large operable openings.
- Electric Bi-Fold System Patented electrically actuated bi-fold system suited for openings up to 8' x 6' high. Uses self-contained electric actuators, requires no auxiliary motor or power unit, and offers a more affordable option for smaller openings. Targets the same architect/contractor/homeowner segments as the hydraulic bi-fold line.
- Hydraulic Single Swing System Hydraulically operated single-piece door/window system offering the largest range of available sizes and largest clear-opening height in the product line with quicker operation speeds. Features a remotely mounted power unit for quieter operation and a no-floor-track design. Targets commercial and luxury residential installations needing large single-leaf openings.
- Electric Single Swing System Electrically actuated single-swing system covering openings ranging from 12' x 5'-6\" to 10' x 7' high. Uses self-contained electric actuators, offers greater headroom and more overhead protection than bi-fold systems, and is suited to hospitality counter-top and pass-through applications.
- Hydraulic 50/50 System Patented hydraulically operated system (Patent 9,567,789) combining bi-fold and single-swing features. Hydraulic cylinders are hidden vertically within jamb housings; design is maintenance-free with no hinges or rollers, and provides a clean opening with minimal exterior space required when open.
- Hydraulic Vertical Lift System Hydraulically actuated system that opens straight up within the incorporated mounting frame and projects neither to exterior nor interior, eliminating conflicts with awnings, furniture, HVAC, lighting, or fire suppression. Available from counter-top size to two-story atriums.
- Powder Coat Finish Service In-house factory powder coating service offering standard, non-standard, and custom color options including full RAL catalogue access. Applied in a controlled, high-performance process for durability, scratch/chip/corrosion resistance, and quick turnaround. Sold as an add-on to Crown Doors systems rather than as a standalone retail offering.

Crown Doors competitors and assessment
Company assessmentEmerging players
- Win-Dor Systems: Win-Dor Systems manufactures custom aluminum sliding and folding door systems for residential and light commercial applications. Comparable as a smaller specialty manufacturer focused on premium custom architectural openings, though more aluminum-frame and residential-leaning.
- Hufcor: Hufcor manufactures operable partition walls and movable wall systems. Hufcor Minnesota is documented as an installation partner of Crown Doors at Target Field and Allianz Stadium, indicating close ecosystem adjacency rather than direct head-to-head competition on door products.
Direct peers
- CornellCookson: CornellCookson manufactures commercial overhead doors, fire doors, and rolling/sectional steel doors for commercial and industrial applications. Comparable US manufacturer of large-format commercial steel door systems, though more focused on overhead/sectional formats than vertical-lift or swing.
- NanaWall Systems: NanaWall is a leading manufacturer of operable glass wall systems, including folding, sliding, and pivot doors for residential and commercial indoor-outdoor applications. Comparable premium architectural category with similar architect-driven, custom-configured sales motion.
- Schweiss Doors: Schweiss Doors is one of the most direct competitors, manufacturing hydraulic and strap-driven bifold doors for commercial, agricultural, and aviation applications. Highly comparable as a US-based specialty manufacturer of large-format hydraulic/bi-fold door systems targeting similar end uses (hangars, commercial openings).
- PowerLift Hydraulic Doors: PowerLift Hydraulic Doors manufactures hydraulic and bifold specialty doors, including one-piece hydraulic lift doors for residential and commercial applications. Direct overlap with Crown Doors' hydraulic single swing and bi-fold product lines.
- LaCantina Doors: LaCantina Doors designs and manufactures large-format folding, sliding, and swing door systems for indoor-outdoor residential and commercial architecture. Comparable as a premium architectural opening specialist serving architects and custom builders, though more focused on glass-paneled folding/sliding systems.
Broad incumbents
- Clopay Corporation: Clopay is one of the largest US manufacturers of residential and commercial garage doors, including insulated sectional doors. Broad incumbent serving similar building opening categories with much larger scale and dealer network — a potential disruptor in the premium segment.
- Overhead Door Corporation: Overhead Door is a major incumbent manufacturer of commercial and residential garage doors, rolling/sectional doors, and operators with national distribution. Adjacent rather than direct competitor, but represents the scaled incumbent Crown Doors could face if premium architectural openings commoditize.
- ASSA ABLOY Entrance Systems: ASSA ABLOY Entrance Systems is the global leader in automated entrance solutions, including sliding, swing, and revolving doors for commercial buildings. Large incumbent with the engineering, capital, and distribution to acquire or replicate specialty door manufacturers at scale.
