Hollow Metal Doors and Frames- Fire Rated Doors and Frames`

At Detroit Door Company, we manufacture, supply, and install fire-rated hollow metal doors, frames, and hardware for commercial, industrial, and institutional buildings throughout Detroit and Southeast Michigan. Our custom-fabricated steel door systems are designed to meet the most demanding fire, security, and building code requirements, providing both strength and life-safety protection.

Every door and frame is built to fit each opening precisely — whether it’s a standard masonry jamb, drywall partition, or a custom retrofit in an existing structure. Detroit Door Company fabricates doors and frames in-house to ensure perfect alignment, smooth operation, and fast turnaround for contractors, property managers, and building owners.

Detroit Door Company manufactures UL and Warnock Hersey fire-rated steel doors and frames in 20-, 45-, 60-, 90-, and 180-minute ratings. Each assembly is fabricated to meet or exceed NFPA 80, NFPA 105, and Michigan Building Code standards.

We produce:

• Single and double hollow metal doors (flush, louvered, or vision-lite)
   
• Custom welded or knock-down frames for masonry, drywall, and metal stud walls
   
• Oversized and undersized doors to fit non-standard openings
   
• Transom, sidelite, and borrowed-lite frames for offices, corridors, and stairwells
   
• Fire-rated frames with reinforcements for closers, strikes, and hardware preps
   
• Factory primed or powder-coated finishes in multiple colors
   

Each door is engineered and manufactured to fit every opening with precision — eliminating field gaps and ensuring a clean, professional installation every time.

We stock and install a full range of commercial-grade door hardware to complete every hollow-metal assembly:

• UL-listed fire-rated hinges and continuous hinges
   
• Door closers (surface-mounted, concealed, and heavy-duty)
   
• Fire-rated locksets, levers, and mortise hardware
   
• Panic devices, vertical rods, and coordinators
   
• Electric strikes and magnetic locks for access control
   
• Smoke seals, gasketing, thresholds, and weatherstripping
   
• Vision lites with fire-rated glass and metal lite kits
   

Our hardware partners include HES, Securitron, DormaKaba, Schlage, LCN, Von Duprin, and Pemko — brands known for long-term reliability and code compliance.

Unlike big-box suppliers, Detroit Door Company manufactures steel doors and frames to fit every unique opening — no matter the size, wall type, or condition of the existing structure.

Whether you need:

• Replacement doors for schools, hospitals, and government facilities
   
• Custom jambs for concrete block, poured walls, or drywall partitions
   
• Retrofit frames for renovation or remodel projects
   
• Welded assemblies for new construction or secure areas
   

We measure, fabricate, and install each system to ensure a tight, secure, and code-compliant fit — saving you costly delays and rework.

Our fire-rated hollow metal doors and frames are ideal for:

• Commercial buildings and office complexes
   
• Industrial plants and manufacturing facilities
   
• Schools, universities, and hospitals
   
• Apartment and condominium corridors
   
• Stairwells, boiler rooms, and mechanical spaces
