Commercial Hollow Metal Double Doors
Hollow Metal Double DoorsCommercial Steel Pairs
Heavy-duty steel door pairs for commercial, industrial and institutional openings — built and prepped by Universal Fireproof Door. Equal or unequal pairs up to 8'0" wide, fire-rated pairs available, with the astragals, flush bolts and exit hardware to match.
Wide openings, built to take abuse
A double door gives you a wide, clear opening for equipment, carts and crowds while each leaf stays a manageable size. Hollow metal pairs are the standard for schools, hospitals, offices, warehouses, mechanical rooms and building entrances — durable, secure and available with fire ratings.
Wide clear opening
Pairs up to 8'0" wide move equipment, deliveries and foot traffic without oversized single leaves.

How do you want the pair to work?
Pick the setup that fits your opening — we prep both leaves to match.
Lock + flush bolts
Active leaf with a cylindrical or mortise lock; inactive leaf held by top and bottom flush bolts with a lock strike.
Rim exit device + flush bolts
Active leaf with a rim panic device; inactive leaf with flush bolts and an overlapping strike.
Push / pull, both active
Both leaves swing freely with push plates and pulls — common for corridors and service areas.
Rim devices + removable mullion
Both leaves active with rim exit devices closing against a removable center mullion.
Surface vertical rods
Both leaves active with surface vertical rod exit devices, with or without the bottom rod.
Concealed vertical rods
Both leaves active with concealed vertical rod devices for a clean, tamper-resistant face.
Astragals, bolts & coordinators
The parts that make a pair close, latch and seal correctly — quoted with your doors.
Flat astragal
Mounted on the active leaf of out-swinging pairs to cover the meeting edge and stop light, drafts and prying.
Z / wrap-around astragal
Mounted on the inactive leaf of in-swinging pairs, with cutouts for flush bolts and strike.
Flush bolts
Manual or automatic top and bottom bolts that hold the inactive leaf closed, with a dustproof floor strike.
Coordinator
Makes the inactive leaf close first so the astragal seals — required on rated pairs with fire exit hardware.

Double door questions
What comes with a hollow metal double door?
The pair of leaves, primed and prepped for the hardware you specify, with hinge and closer reinforcements built in. Frames, exit devices, flush bolts, astragals, coordinators, glass and louvers are quoted as add-ons, so you only pay for what the opening needs.
Are your double doors fire rated?
Yes — pairs can be built and labeled for fire-rated openings, including 20-, 45-, 60-, 90-minute and 3-hour applications. Rated pairs need the correct astragal, flush bolts or rated exit devices, and a coordinator where required. Tell us the rating on your plans and we will match the components.
Do I need an astragal?
Usually, on single-swing pairs. Rated pairs typically need a steel overlapping astragal, though some double-egress pairs and lower ratings may not — always confirm against the label requirements. Astragals are not used with open-back strikes or with pairs using double vertical rods.
What finish do the doors come in?
Doors ship with a factory-applied, rust-inhibiting gray primer. Primer is not a finish coat, so plan to paint the doors after installation.
Can you build unequal pairs or odd sizes?
Yes. We fabricate equal and unequal pairs and custom widths and heights in our Brooklyn shop. Send the overall opening size and the leaf split you want.
