Maximum Security & Fire Protection for Detroit Facilities
Why Hollow Metal Outperforms Wood and Aluminum in Industrial Settings
Industrial facilities throughout Detroit, Warren, Sterling Heights, and Livonia require entry systems capable of resisting forced entry attempts, daily forklift corridor impacts, and harsh winter road salt:
A60 Galvannealed Rust Defense
Standard cold-rolled steel rusts through within 3 Michigan winters. Our A60 zinc-iron alloy coating chemically bonds paint and resists moisture corrosion permanently.
Heavy-Gauge Welded Frames
Knock-down frames fail under crowbar prying. We install factory-mitered, fully welded 14-gauge frames with heavy masonry strap anchors embedded into mortar joints.
Thermal & Acoustic Insulation
Foamed-in-place polyurethane or polystyrene core options achieve R-values up to 11.0, stopping heat loss in exterior warehouse walls and cutting heating utility bills.
Certified Fire-Rated Assemblies
Our 90-minute and 3-hour fire-rated steel doors feature mineral fiberboard cores and intumescent seals that expand under heat, fully compliant when paired with certified fire exit crash hardware and Grade 1 commercial closers.
Standard 3070 and 4070 16-gauge fire-rated steel slabs, welded masonry frames, and hardware prep ready for fast Metro Detroit delivery and installation.

16-Gauge vs. 18-Gauge vs. 14-Gauge Hollow Metal Doors
Steel thickness is the first decision on a hollow metal door. The Steel Door Institute groups doors into duty levels by face-sheet gauge. A lower gauge number means thicker steel.
| Face sheet | SDI duty level | Where it belongs | Trade-off |
|---|---|---|---|
| 18-gauge | Level 2, heavy duty | Interior offices, corridors, light commercial exits | Lowest cost; dents under cart and pallet-jack traffic |
| 16-gauge | Level 3, extra heavy duty | Exterior exits, warehouses, schools, stairwells | Our standard for exterior Detroit openings |
| 14-gauge | Level 4, maximum duty | Loading docks, detention, high-abuse industrial openings | Heaviest slab; needs heavy-weight hinges and a stronger closer |
What Is the Difference Between A60 Galvannealed and Cold-Rolled Steel Doors?
Cold-rolled steel is bare carbon steel with a factory primer on top. It is fine indoors, but once the primer is scratched on an exterior door, road salt and meltwater reach the steel and rust starts at the bottom edge and the hinge side.
A60 galvannealed steel is coated with a zinc-iron alloy before the door is formed. The coating is part of the sheet, so a scratch does not open a path to bare steel, and its matte surface holds paint well. For any exterior opening in Southeast Michigan, galvannealed is the specification that survives winter. Cold-rolled is reserved for dry interior openings where cost matters more than corrosion resistance.
How Long Does Hollow Metal Door Replacement Take?
A slab swap in a sound frame takes two to three hours on site once the door is in hand. Stock 3'-0" x 7'-0" and 4'-0" x 7'-0" doors are normally available within 24 to 48 hours. A full frame replacement in masonry is a scheduled job of two to four days because the old frame has to be cut out, the new frame anchored and grouted, and the opening secured overnight. Non-standard sizes, lite kits, and special fire ratings are built to order, and lead time is confirmed on the written quote.

For exterior security openings and industrial loading docks in Detroit, we recommend 16-gauge or 14-gauge A60 galvannealed steel. A60 zinc coating protects the steel from salt corrosion, moisture penetration, and severe mechanical abuse far better than lighter 18-gauge or 20-gauge cold-rolled doors.
Our hollow metal doors and welded steel frames carry UL 10B, UL 10C, and NFPA 252 certifications for 20-minute, 45-minute, 90-minute (1.5-hour), and 180-minute (3-hour) positive pressure fire ratings. Each assembly includes an embossed physical UL certification label.
