Custom Double Exterior Front Doors Factory Direct | Jusen

11 min read

The last time we shipped a double exterior front door to a coastal project in Florida, the buyer had one concern that outweighed everything else: hurricane-rated wind load. Not the wood grain. Not the handle finish. Wind pressure.

That is the reality of selling large-format doors. When the opening is twice the width of a standard entry, every engineering decision matters more. The frame has to be stiffer. The glazing has to be thicker. The hardware has to carry more weight. And if the factory cuts corners on any of those, the door fails on site — not in the showroom.

We build double exterior front doors from our factory in China, and we have spent the last decade learning exactly where those corners get cut. This article walks through what we do differently, what you should ask any supplier before committing, and how to get a double door that actually performs.

Why Choose a Double Exterior Front Door for Your Project?

A double door changes the psychology of an entrance. It signals scale. For luxury villas, boutique hotels, and high-end commercial storefronts, that visual weight is often the entire point of the design.

But the aesthetic benefit comes with an engineering cost. A double exterior front door has twice the perimeter of a single door — which means twice the opportunity for air leakage and water infiltration. The astragal (the vertical seam where the two doors meet) is the weakest point on any double door system. If the profiles do not have a proper interlock or weatherstripping setup, that seam becomes a draft channel in winter and a leak path in rain.

We manufacture both solid wood and thermal-break aluminum double doors in our factory. The choice between them depends on your project’s climate and architectural style. For modern builds, our aluminum doors with polyamide thermal break strips deliver the slim sightlines architects want without sacrificing insulation values. For traditional or heritage-style projects, our solid wood doors can be crafted in oak, mahogany, or teak with matching sidelites.

One imperfect insight worth stating plainly: wood doors are not always the right answer. In high-humidity coastal regions or buildings near salt water, wood expands, warps, and requires constant maintenance. Aluminum with proper thermal break handles those environments far better. We have told buyers this even when it meant losing the wood door order. A door that fails in year three damages your reputation, not just the building.

Thermal Performance and Insulation

The thermal break is not a marketing term. It is a physical barrier — typically polyamide strips — that separates the interior and exterior aluminum profiles so heat does not conduct directly through the frame. On a double door with a 72-inch opening, that separation can reduce heat transfer through the frame by as much as 70% compared to non-thermal-break profiles.

We adjust the width of the thermal break and the glazing configuration based on your target market’s building codes. For projects in northern Europe or Canada, that might mean a 34mm thermal break with triple glazing. For projects in Singapore or Dubai, a 24mm break with double Low-E glass is usually sufficient. Our engineering team reviews your local energy codes before we finalize the profile drawings — we do not assume one spec fits all regions.

Security and Durability

Large door panels are heavy. A double door with two active panels can weigh 80 to 120 kilograms per leaf depending on height, glass thickness, and frame material. Standard hinges will sag within months under that load.

We use heavy-duty stainless steel hinges rated for 150kg per pair, and we offer multi-point locking systems with 5 to 7 locking points per door leaf. For commercial projects, we can fit panic bars or emergency egress hardware that complies with local fire safety regulations. The hardware accessories are fully customizable — you specify the brand, the finish, and the locking mechanism, and we source or fabricate accordingly.

Customization Options for Your Double Door Specifications

Every project has unique dimensions. That sounds obvious, but many suppliers still push standard sizes because it simplifies their production line. We do not do that. Our factory is set up for custom fabrication — we cut, mill, and assemble profiles to your exact opening dimensions.

If you need a 60-inch wide opening, we build to 60 inches. If you need 72 inches with a transom above, we build to that spec. We have produced double doors as wide as 96 inches for commercial storefronts, and as narrow as 48 inches for residential side entrances. The tooling adjusts, not the other way around.

Size, Configuration, and Glass Selection

Double doors come in two primary configurations. An “active/inactive” pair has one fixed leaf and one operating leaf — useful when you want the grand appearance but only need daily access through one side. A “French” double door has both leaves operable, which maximizes the opening width for moving furniture or for crowd flow in commercial settings.

We manufacture both configurations. The choice affects hardware, weatherstripping, and the astragal design — an active/inactive door needs a flush bolt on the inactive leaf, while a French door needs a coordinated locking system on both leaves. We will walk you through the options and recommend the configuration based on traffic flow and egress requirements.

For glass, we offer clear, frosted, Low-E, laminated, and insulated glazing units. For double doors facing west or south, Low-E glass with a low solar heat gain coefficient reduces cooling loads significantly. For privacy applications, we can use frosted or patterned glass.

Color and Hardware Finishes

Aluminum frames can be powder coated in virtually any RAL color. We also offer anodized finishes in silver, bronze, and black. For wood doors, we offer a range of stains — from natural clear coats to deep walnut or ebony finishes.

The hardware finish matters more than most buyers expect. A brushed nickel handle on a black aluminum frame looks intentional. A polished chrome handle on the same frame looks like a mistake. We keep samples of our standard hardware finishes in our showroom, and for bulk orders we can produce custom-matched finishes to align with your architectural hardware schedule.

OEM/ODM and Private Label Services

This is where we differ from most trading companies. We are the factory, so we can produce double exterior front doors under your brand name. We handle everything — profile design, tooling, production, and packaging — so you get a branded product without owning a manufacturing facility.

For ODM projects, we work with your design team to create unique profiles or incorporate specific features like hidden hinges, integrated LED lighting, or custom astragal designs. For OEM projects, you provide the drawings or samples, and we reverse-engineer and produce to match. We have done both for clients across North America, Europe, Australia, and the Middle East. [1]

The Jusen Manufacturing Process: Precision and Quality Control

Our factory operates as an integrated production line. We do not outsource critical steps. The aluminum profiles are cut and milled in-house. The glass units are assembled in our clean room. The hardware is fitted and adjusted before the door leaves the floor.

Why does that matter to you? Because vertical integration means accountability. When something goes wrong, we do not blame a subcontractor. We fix it in our own facility, before the door is crated.

The production process for a double exterior front door typically takes 15 to 30 working days depending on complexity. The sequence is:

• Profile cutting and machining
• Corner crimping and frame assembly
• Thermal break insertion and rolling
• Glass unit fabrication and sealing
• Hardware installation and adjustment
• Weatherstripping and astragal fitting
• Final quality inspection

Each step has a checklist. The frame is checked for squareness within 1mm tolerance. The door leaf is checked for flatness and twist. The hardware is cycled 50 times to verify smooth operation.

Rigorous Performance Testing

The tests that matter for double doors are air-tightness, water-tightness, and wind resistance. These are not optional checks for us — they are part of our standard pre-shipment inspection protocol.

We test air-tightness by pressurizing the door assembly and measuring air leakage through the frame and astragal. Water-tightness involves spraying the door with a controlled water flow at increasing pressure levels to simulate rain and wind. Wind resistance tests apply static pressure to the door surface to check for deflection and structural integrity.

For double doors, these tests are especially critical because the large surface area and center seam create more failure points than single doors. We have seen doors from other suppliers pass a single-door test but fail when scaled up to double-door dimensions. That is why we insist on testing the actual double door assembly, not just a single leaf.

Packaging for Export

A double exterior front door is large, heavy, and expensive. If it arrives damaged, the project stops. That is why our export packaging is designed for the realities of container shipping, not the showroom floor.

We use heavy-duty plywood crates with internal bracing that prevents the door from shifting during transit. Each door is wrapped in a protective film that guards against scratches and moisture. For LCL shipments where the crate may be handled multiple times, we add additional corner protection and reinforcement.

We have shipped double doors to more than 30 countries. The packaging protocol is refined based on feedback from freight forwarders and installers about what works and what does not.

Logistics and Supply: How We Support Your Construction Timeline

Construction schedules are unforgiving. A door that arrives late delays the entire fit-out. A door that arrives damaged triggers a replacement process that can take weeks.

We treat logistics as part of the product. When you place an order, we confirm the production timeline and the shipping schedule before we start cutting profiles. We do not quote a lead time we cannot meet.

Flexible Shipping

We ship both FCL (full container load) and LCL (less than container load). For developers ordering dozens of doors for a multi-unit project, FCL is usually the most cost-effective option. For contractors or importers who need just a few units, LCL lets you order smaller quantities without paying for a full container.

Direct delivery from our China factory to your port of entry is standard. We have worked with freight forwarders across all major shipping lanes, and we can recommend a logistics partner if you do not have one.

Export Documentation and Compliance

Foreign trade paperwork can derail a project if it is incorrect. We provide a complete set of customs documents with every order — packing list, proforma invoice, commercial invoice, and bill of lading. Our export team has handled shipments to North America, Europe, Australia, the Middle East, and Southeast Asia. [2]

We also understand that building codes vary. Our adjustable profile structure and fittings are designed to comply with international standards, and we can adapt the thermal break width, glass thickness, and hardware configuration to meet local regulations in your target market.

What is the typical lead time for a bulk order of double exterior front doors? Lead time varies based on quantity and customization, but usually ranges from 15 to 30 days after sample approval. We work with you to schedule production around your construction deadlines. For urgent projects, we have expedited production in as little as 10 working days — but that requires that the specifications are finalized and the materials are in stock.

Can you manufacture double doors to match specific local building codes? Yes. Our adjustable profile structure and fittings are designed to meet international standards. We adapt the thermal break width and glass thickness to comply with energy codes in your country or state. For example, projects in the EU often require specific U-values that differ from US requirements. We review the code before production, not after.

What is the MOQ for a custom project? We do not impose a rigid MOQ for our standard custom sizes. We handle both large-scale project bulk supply and smaller LCL shipments. That said, for fully bespoke ODM designs that require new tooling, the tooling cost is amortized across the order quantity. Contact us with your specifications, and we will provide a clear quote that includes any tooling costs.

Do you offer spare parts or hardware replacements? Yes. We stock the hardware accessories we use in our production line. We provide spare locks, hinges, handles, and weatherstripping with bulk orders, and we can ship replacements separately if needed. This is important for projects that need on-site installation spares or future maintenance.

Can you produce a “double door” that acts as a single swing unit? Yes. We manufacture both active/inactive double doors where one side is fixed and French double doors where both sides swing. The configuration affects hardware, astragal design, and weatherstripping. We help you select the right setup for traffic flow and egress requirements.

Decision Guide

Choose an active/inactive double door if:

• You want the grand appearance but only need daily access through one leaf
• You have limited interior floor space for door swing
• You need a wider fixed glass panel for natural light

Choose a French double door if:

• You need the full opening width for moving furniture or equipment
• You are designing for commercial crowd flow
• You want symmetrical design with both handles visible

Choose aluminum with thermal break if:

• Your project is in a coastal or high-humidity environment
• You need slim profiles for a modern aesthetic
• Your local energy codes require specific U-values

Choose solid wood if:

• Your project is a heritage or traditional building
• The interior and exterior design calls for natural wood grain
• You accept the maintenance requirements of wood in your climate
