Double Commercial Doors Built for Wide Openings
Steel double leaf commercial doors built for wide-opening applications — lobbies, loading corridors, institutional entrances, and high-traffic commercial builds.
Every pair ships with matched leaves, pre-hung frame options, and hardware pre-fitted to your spec — so your installation crew isn't improvising on site.
What Makes a Double Leaf Commercial Door Different from a Single
Double commercial doors — two independently hung leaves sharing a common frame — solve a specific problem: openings too wide for a single leaf to span without excessive weight and sag. The standard single commercial door tops out around 1,200mm leaf width before the door starts pulling at the hinges and the frame-to-leaf gap opens up over time.
A double leaf commercial door splits that load across two leaves, each running 700–1,000mm wide, so the structural math works and the door operates cleanly for years.
That's the mechanical reason. The commercial reason is different: wide openings move more people, more equipment, and more product per minute. Lobbies, hospital corridors, school main entrances, warehouse access points — these are all locations where a single door creates a bottleneck that costs your downstream customer real money in operational friction.
When you're sourcing for a contractor or stocking for a distributor, the double leaf configuration opens up a segment of projects that a single door simply can't serve.
We've been manufacturing double leaf commercial doors since 2008. The coordination challenge — getting two leaves to hang plumb, seal consistently at the meeting stile, and operate without binding — is where most of the production difficulty lives.
Load Distribution
Two leaves share the structural load — no hinge pull, no frame gap over time.
Wide Clear Opening
1,400–2,400mm combined width — spans what a single leaf structurally cannot.
Throughput
Moves more people, equipment, and product per minute — eliminates operational bottlenecks.

The Meeting Stile: Where Double Doors Either Work or Don't
Most buyers focus on the leaf specs — steel gauge, finish, hardware. The meeting stile is where the real quality difference shows up in the field, and it's the detail that separates a door that looks fine in the showroom from one that still seals properly after two years of daily use.
The meeting stile is the vertical edge where the two leaves come together at the center of the opening. On a poorly made double door, this joint is the first place you see problems: light gaps, air infiltration, the passive leaf dropping and dragging on the floor, the active leaf not latching cleanly because the passive leaf has shifted. These aren't cosmetic issues — they're warranty claims and callbacks for your customer.
We started specifying neoprene on the meeting stile after a Gulf distributor came back to us with a batch of doors that had lost their seal in under a year — the foam tape couldn't handle the temperature cycling between air-conditioned interiors and 45°C exteriors. The neoprene spec has been standard on all our double doors since 2019.
The result: your downstream customer gets a door pair that operates and seals consistently for the life of the building, not just through the warranty period. For a distributor, that means zero callbacks on this joint. For a contractor, it means the door passes the building inspector's air infiltration check the first time.
Welded Astragal, Not Screwed
The T-profile astragal is roll-formed from 1.5mm steel and welded to the active leaf. Screwed astragals back out under repeated impact; welded ones don't.
Mortised Strike Plate
The passive leaf gets a recessed strike plate mortised into the stile edge — not surface-mounted — so latch engagement depth stays consistent regardless of how many times the door is slammed.
8mm Neoprene Compression Seal
Continuous neoprene seal runs the full height of the meeting stile. Foam tape compresses permanently within 18 months in high-traffic environments. Neoprene doesn't.
Roll-formed and welded — not screwed — to the active leaf on a dedicated CNC profile line.
Continuous compression seal along the full stile height. Standard on all double doors since 2019.
Welded astragal and mortised strike plate eliminate the two most common meeting stile failure modes.
Matched Set Shipping
Each pair of leaves is cut, formed, and finished together, then tagged to their frame. The frame and leaves ship in the same container, labeled with the same order reference.
Your installer pulls the set, hangs it, and moves on — no sorting through a mixed pallet trying to find which leaf goes with which frame.
Pre-Hung Option for Large Projects
For orders of 100 pairs or more, we can pre-hang the leaves in the frame at the factory, wrap the assembly, and ship as a complete pre-hung unit. This adds freight volume but eliminates on-site hanging time entirely — which matters when your contractor is working against a project schedule.
Frame-to-Leaf Fit: The Tolerance That Determines Installation Speed
A double door frame has four critical dimensions: two leaf reveals (left and right), the head clearance, and the center gap between leaves. All four need to land within ±1.5mm of spec for the door to hang plumb and operate without adjustment.
We hold ±1.0mm on frame fabrication and ±0.8mm on leaf width — tighter than the industry standard — because we've learned that loose tolerances don't show up as a problem until the installer is on site trying to make a door work in a frame that was built to a different dimension.
We've had buyers come to us specifically because their previous supplier was shipping frames and leaves as separate line items from different production runs. The dimensional variation between batches was enough to cause fit problems on a meaningful percentage of openings.

Market Segments Where Double Commercial Doors Move Volume
Double commercial doors are a recurring line item across five distinct construction and facility segments. Understanding where volume concentrates helps you position supply relationships and forecast reorder cycles.
Institutional — Schools, Hospitals, Government
Main entrances, corridor intersections, and emergency egress points. A typical mid-size school project runs 20–60 pairs. Districts and government agencies procure on annual or multi-year contracts — a contractor who wins one project often has a repeatable supply relationship for 3–5 years.
Commercial Office & Mixed-Use Development
Lobby entrances, elevator lobbies, and conference suite entries are standard double door locations. Developers are price-sensitive on commodity specs but will pay for consistent quality and reliable lead times — a delayed door shipment holds up a certificate of occupancy, which costs the developer real money.
Hospitality — Hotels, Resorts, Convention Centers
Hotel main entrances and ballroom dividers are high-visibility applications where finish quality and hardware specification matter. Projects often require custom sizes and specific hardware packages — panic hardware, electromagnetic hold-opens, card access prep. MOQs per project are lower (10–30 pairs) but margin per unit is higher.
Industrial & Warehouse Access
Personnel access doors in warehouse and manufacturing facilities are often double leaf to accommodate equipment movement. These applications prioritize durability over aesthetics — 1.2mm steel, heavy-duty hinges, simple hardware. Order volumes per facility run 10–50 pairs, and facility managers reorder when they expand or renovate.
Retail & Storefront
Chain retailers and shopping center developers standardize their door specifications across locations. A distributor who gets approved as a supplier for a retail chain can see consistent reorder volume across dozens or hundreds of locations. Double doors at main retail entrances are a standard spec for stores above a certain footprint.
Customization Parameters and What They Mean for Your Order
Double commercial doors have more customization variables than single doors — two leaves, a shared frame, and coordinated hardware all need to be specified together. Here's what we can configure and where the practical limits are.
Opening Dimensions
Leaf widths from 700mm to 1,200mm per leaf, heights from 2,000mm to 3,000mm. Non-standard sizes are available on runs of 50+ pairs — below that, the tooling changeover cost doesn't make sense for either side.
Practical Note
If your project has an unusual opening size, send us the rough opening dimensions and we'll confirm the leaf and frame spec.
Steel Gauge
Standard is 1.0mm face sheet on 1.5mm frame. For high-abuse environments — loading docks, institutional corridors with cart traffic — we recommend 1.2mm face sheet.
Weight Impact
The weight increase is roughly 8–10% per leaf at 1.2mm. Factor that into your hardware spec — heavier leaves need heavier hinges and a stronger closer.
Core Fill
Honeycomb paper is standard and sufficient for most commercial applications. Mineral wool core is available for projects requiring acoustic performance or thermal insulation.
Honeycomb Paper
Standard. Sufficient for most commercial applications. Shorter lead time.
Mineral Wool
STC 32–38 acoustic. Thermal insulation. Adds cost and lead time — specify at order.
Surface Finish
Automated powder coat in any RAL color, 60–80μm DFT, 500-hour salt spray tested. Primer-only finish is available if your customer wants to paint on site, though we don't recommend it for exterior applications.
Factory vs Field
The factory powder coat is more durable than field-applied paint in every environment we've tested. For exterior applications, factory finish is the right call.
Hardware Packages
We can pre-fit locksets, door closers, panic hardware, floor bolts, and electromagnetic hold-opens at the factory. Pre-fitted hardware reduces installation labor cost and eliminates the risk of field-fitted hardware that doesn't match the door prep.
Ordering Note
Specify your hardware package at order. We'll confirm compatibility with the leaf weight and configuration before production.
Fire Rating
30-minute and 60-minute fire-rated configurations are available. Fire-rated double doors require intumescent seals at the meeting stile and perimeter, a coordinated frame with intumescent seal groove, and certified hardware.
Specify Upfront
Fire rating affects the frame design, not just the leaf. If your project requires fire rating, this must be specified at order — it cannot be added after production begins.
OEM & Private Label Programs
We support full OEM programs — your brand, your packaging, your documentation. Minimum 100 pairs for OEM runs. Free 3D rendering and design consultation included.
Container Loading and Landed Cost Planning
Double commercial doors ship knocked down (KD) — leaves and frame as separate flat-pack components — unless you've specified pre-hung assemblies. KD packing is the right choice for most import orders: it maximizes container utilization and reduces the risk of damage to pre-hung assemblies during port handling.
Typical Container Loading (KD Double Door Sets)
Standard 2,100 × 1,800mm opening. Figures vary with leaf size and packaging configuration.
| Container Type | Approximate Loading |
|---|---|
| 20GP | 80–100 pairs |
| 40HQ Recommended | 180–220 pairs |
For landed cost calculation, use 40HQ as the baseline — the per-unit freight cost difference between 20GP and 40HQ is significant enough that most buyers consolidate to 40HQ once they're past the trial order stage.
Face-to-Face Packing
Leaves packed face-to-face with foam interleaving between each pair, banded to a pallet. Frames bundled separately. Corner protectors on all edges.
Under 0.5% Damage Rate
This packing spec has been tested through multiple shipments to North America, the Middle East, and Australia. Port handling damage rate on properly packed KD sets is under 0.5%.
2% Spare Frame Components
The frame is the component most likely to arrive with minor transit damage (corner dents from forklift handling). Orders over 50 pairs include 2% spare frame components as standard practice.
Frame Transit Note for New Importers
For buyers new to importing double doors: the frame is the component most likely to arrive with minor transit damage. We pack frames with additional corner protection and include 2% spare frame components on orders over 50 pairs as standard practice.

Sourcing Double Commercial Doors: Common Questions
What is the minimum order quantity for double commercial doors?
50 pairs for standard configurations (standard sizes, standard RAL colors, standard hardware). Custom sizes or non-standard configurations start at 100 pairs. If you're evaluating the product before committing to a full order, we can arrange a sample pair — contact us to discuss.
What is the standard lead time for a production order?
15–25 days for standard configurations after order confirmation and deposit. Custom configurations (non-standard sizes, special hardware, fire-rated) run 25–35 days. These are production lead times; add your freight transit time for landed delivery planning.
Double leaf commercial door vs. single door with sidelight: which is better for wide openings?
It depends on the application. A single door with fixed sidelights gives you a wider visual opening but only one operable leaf — fine for lobbies where you want the look of a wide entrance but don't need to move large equipment or high pedestrian volumes simultaneously. A double leaf commercial door gives you the full opening width as operable clearance, which matters for ADA compliance on wide openings, emergency egress, and any application where equipment or carts need to pass through. For institutional and commercial builds where the full opening needs to be operable, double leaf is the correct specification.
What steel gauge should I specify for a high-traffic institutional application?
For standard office and retail traffic, 1.0mm face sheet is sufficient. For institutional corridors with cart traffic, loading dock personnel doors, or any application where the door takes regular impact from equipment, specify 1.2mm face sheet with heavy-duty 4-hinge configuration per leaf. The 1.2mm spec adds roughly 10% to the unit cost but eliminates the denting and deformation that generates warranty claims in abuse environments.
Can double commercial doors be supplied with panic hardware for egress compliance?
Yes. We pre-fit panic hardware (push bar / cross bar style) at the factory. For double doors, the active leaf gets the panic device and the passive leaf gets a coordinated flush bolt or automatic flush bolt. Specify the egress hardware requirement at order — it affects the door prep and frame strike configuration.
What happens if one leaf arrives damaged?
We include 2% spare components on orders over 50 pairs. For individual damaged leaves on smaller orders, we can supply replacement leaves as a separate shipment — because we tag matched sets, we have the exact dimensions on file and can reproduce a replacement leaf to the original spec.
