Next Door Company

What Next Door Company does

Next Door Company, founded in 1993 and headquartered in Hialeah, Florida, is a specialty manufacturer of stainless steel and hollow metal doors and frames serving commercial and institutional construction markets in the U.S. and internationally. The company operates a 60,000 sq ft LEAN manufacturing facility equipped with CNC-controlled bending, forming, shearing, and assembly equipment, alongside TIG welding capabilities for stainless steel fabrication. It was the first manufacturer in North America to exclusively produce stainless steel doors and frames and is now in its fourth generation of family ownership, operating as a subsidiary of Allegion.

The company's two core product lines are Stainless Steel Doors and Frames (manufactured from Type 304 and Type 316 alloys) and Hollow Metal Doors and Frames (manufactured from galvannealed steel), both offered in standard and custom non-standard configurations that typical hollow metal manufacturers decline to produce. Specialty variants include fire-rated assemblies (up to 3 hours, Warnock Hersey labeled), sound-rated assemblies (up to STC 51), hurricane-rated assemblies for High Velocity Hurricane Zones (up to +/-90 PSF, Miami-Dade NOA and Florida Building Code approved), and stainless steel elevations, vision kits, louvers, and hospital stops for healthcare and pharmaceutical environments. Differentiating technical features include 100% stainless steel interior components and anchors to prevent galvanic corrosion, hidden channel weld construction to preserve surface finish, and TIG welding to avoid heat tinting.

Next Door sells exclusively through qualified door and hardware distributors in the U.S. and internationally, with quote-based pricing, a 1-2 business day typical quote turnaround, and supplementary direct enterprise field sales for large institutional projects. Customer segments span airports and transportation, healthcare, food and beverage processing, pharmaceutical manufacturing, luxury hospitality, government and cultural institutions, public housing, water treatment, and industrial manufacturing, with named installations including Newark Liberty International Airport, JFK, Reagan National, Pfizer, Merck, Coca-Cola Enterprises, Nestle Purina, Cleveland Clinic, MIT, NYC Housing Authority, and Boeing. Geographic reach includes the U.S., Canada, UAE, Qatar, Puerto Rico, Dominican Republic, Guam, Marshall Islands, and Palau.

Direct peers

• Steelcraft: Allegion's flagship hollow metal door and frame brand, making Steelcraft a direct in-house sibling competitor within the same parent company and overlapping product categories (commercial hollow metal doors, frames, and architectural openings).
• Ceco Door: Assa Abloy's hollow metal door and frame brand serving commercial and institutional construction; directly comparable product portfolio (standard and specialty hollow metal doors/frames) and end markets.
• Curries: Assa Abloy hollow metal door and frame brand specializing in standard and custom configurations for commercial, healthcare, and educational buildings — overlapping both product line and customer base with Next Door.
• Republic Doors & Frames: Independent hollow metal door and frame manufacturer offering standard and custom commercial door assemblies; competes for the same non-residential specification-driven bids as Next Door.
• Deansteel Manufacturing: Custom and standard hollow metal door and frame manufacturer serving commercial and institutional projects, including hurricane and fire-rated assemblies — directly comparable to Next Door's specialty product positioning.
• Mesker Door: Hollow metal door and frame manufacturer producing fire-rated, hurricane-rated, and security door assemblies for commercial construction; comparable in product breadth and end-market focus.
• Amweld International: Specialty commercial hollow metal door and frame manufacturer with focus on custom configurations and rated assemblies — directly comparable to Next Door's special-purpose positioning.
• Windsor Republic Doors: Hollow metal door manufacturer serving commercial and institutional construction with standard and custom hollow metal products; competes in the same specification-driven bid environment.

Emerging players

• Steel Shield Security: Smaller specialty door manufacturer focused on security and blast-resistant commercial door assemblies; overlaps with Next Door's higher-performance-rated niche (hurricane, security, fire) but narrower product line.

Regional players

• HMF Express: Hollow metal frame and door supplier focused on the U.S. Southeast and Texas markets; competes with Next Door in regional commercial construction bids with a more limited geographic footprint.
