Commercial Workhorses

Durability, Security & Fire Protection

Hollow metal steel doors and frames are the industry standard for commercial exterior entries, stairwell egress routes, and rated mechanical rooms.

Over time, heavy forklift traffic, frame rust, or sagging hinges cause steel leaves to bind against frames or fail positive latching tests. We diagnose the entire opening—adjusting continuous hinges, realigning strikes, or replacing rusted frames with fully code-compliant UL-labeled steel assemblies.

Hollow Metal Applications

  • Exterior Egress Doors: Insulated steel doors with panic bars and weather seals.
  • Stairwell Fire Doors: UL-labeled 90-minute and 3-hour fire separation doors.
  • Mechanical & Storage Rooms: Heavy-gauge steel leaves with Grade 1 lever locks.
  • Industrial & Warehouse: Impact-resistant steel doors with kick plates and armor protection.
Common Failure Modes

Steel Door & Frame Faults We Correct

Common issues encountered by property and facility managers in commercial buildings.

Frame Sag & Latch Misalignment

Security & Fire Risk

Settling walls or worn hinges cause steel leaves to drop, stopping latch bolts from entering strike plates. Corrected via hinge shimming, continuous hinge retrofits, or strike realignments.

Rust & Moisture Deterioration

Structural Decay

Moisture and salt cause steel frame jambs to rust out at the floor anchors. We weld patch frame anchors or replace damaged frames with zinc-coated steel assemblies.

Equipment & Traffic Impact

Impact Damage

Forklifts, carts, or hand-trucks denting steel skins and twisting frame headers. Resolved with heavy-gauge armor plates or leaf replacements.

Unapproved Modifications

NFPA 80 Violation

Field-drilled holes or kick-down doorstops installed on fire-rated steel doors. We perform code-compliant repairs or supply properly labeled replacement leaves.

Frequently Asked Questions

Hollow Metal Door FAQ

Can rusted steel frames be repaired, or must they be replaced?
Minor surface rust can be sanded and sealed. If the floor anchors or lower jambs are rusted through, replacing the frame section or full frame is required for structural security.
Are hollow metal doors automatically fire-rated?
Not always. While most commercial steel doors can carry a fire rating, it must feature a legibly attached UL or Intertek certification label on the leaf edge and frame header.
How quickly can replacement hollow metal doors be installed?
Standard commercial sizes (3060, 3070, 4070) are stocked locally for fast replacement. Custom size frames or special hardware cutouts require factory lead times.
