Double Front Door Factory Direct | Custom Sizes & Materials | Jusen

12 min read

A double front door arrived at a job site in New Jersey last spring with a cracked transom frame. The distributor had ordered from a trading company, not a factory. Three weeks of back-and-forth later, the project stalled. That is the difference between buying from a middleman and buying from the people who actually cut, weld, and assemble the product.

We are Jusen Door and Windows Manufacturing Co., Ltd. For over a decade, we have manufactured double front doors and window systems from our factory floor in China, shipping directly to contractors, developers, and importers across North America, Europe, and Australia. This guide covers what we have learned about double front doors — materials, customization, testing, and logistics — from the perspective of the people who build them.

Why Choose a Double Front Door? Design Trends and Functional Benefits

The double front door trend is not fading. Walk through any high-end residential development or commercial entrance project, and you will see why. A double door changes the scale of an entryway. It makes a statement that a single door simply cannot.

Architectural Curb Appeal and Property Value

Real estate studies consistently show that entryway upgrades return between 75% and 100% of their cost at resale [1]. For developers, that means the front door is not an expense — it is an investment in the property’s perceived value.

Double doors work particularly well for custom villa doors and windows projects. The wider opening allows for more glass, more light, and a more dramatic entrance sequence. Our team regularly produces aluminum alloy entrance doors that span 1,800 mm to 2,400 mm in width. When you order from us, you are not limited to stock sizes. We offer full customization on size, color, and glass — so if your architectural drawings call for a 2,100 mm double door with a specific sidelight configuration, that is exactly what we build.

Improved Flow and Accessibility

There is a practical side to double front doors that architects appreciate. Moving furniture in and out becomes significantly easier with a 1,600 mm or wider opening. For commercial spaces — restaurants, clinics, boutique hotels — double doors accommodate higher foot traffic and wheelchair access without the bottleneck of a single door.

The engineering challenge here is weight. A double door panel in solid wood can easily weigh 80 to 100 kilograms. Standard hinges will fail within months. Our factory uses heavy-duty bearing hinges and adjustable profile structures specifically designed for large-format doors. We have spent years refining the hardware specifications so that a 2,000 mm tall door opens and closes smoothly, year after year.

Enhanced Natural Light and Ventilation

Double doors with full-glass panels transform a dark entryway. But glass is also the weakest point for thermal performance. This is where our thermal-break aluminum doors and windows expertise matters. We use multi-chamber profiles with polyamide thermal breaks, allowing us to fit large glass panels without compromising insulation values. For projects in colder climates, we can supply double or triple-glazed units with low-E coatings.

> Imperfect insight: Double doors are not always the best choice for every facade. On narrow lots or buildings with limited wall space, the extra width can eat into usable interior floor area. And in high-humidity coastal regions, solid wood double doors require more maintenance than aluminum — buyers should weigh aesthetics against long-term durability before committing.

Double Front Door Materials: Solid Wood vs. Thermal-Break Aluminum

The material decision is the first major fork in the road. We manufacture both solid wood and thermal-break aluminum double doors, so we can give you an honest comparison rather than pushing one product line.

The Timeless Appeal of Solid Wood Double Doors

Solid wood double doors carry a warmth that no other material replicates. The grain, the texture, the weight — these are qualities that resonate with buyers of traditional and rustic architecture.

Our solid wood doors go through a controlled kiln-drying process to bring moisture content down to 8–12%. This matters enormously for large-format double doors. If the wood is not properly stabilized, the panels will warp, cup, or crack within the first year — especially in climates with dramatic seasonal humidity swings.

We offer a range of species including oak, mahogany, walnut, and sapele. Each board is finger-jointed or edge-glued to minimize movement, and we apply a multi-coat finish that resists UV fading and moisture penetration. For projects that require fire ratings, we can engineer the core construction to meet specific standards while maintaining the wood veneer appearance.

The Performance of Thermal-Break Aluminum Double Doors

For modern architecture, thermal-break aluminum is often the better choice. The slim sightlines allow for larger expanses of glass, and the structural rigidity means the door will not sag or rack over time.

Our thermal-break aluminum double doors use polyamide strips to separate the interior and exterior aluminum profiles. This creates a thermal barrier that significantly reduces heat transfer. In our factory, we test every batch for air-tightness, water-tightness, and wind resistance. These are not optional checks — they are part of our pre-shipment inspection protocol. A double door that leaks air or water will fail inspection on site, and that costs everyone time and money.

Aluminum also offers superior corrosion resistance for coastal projects. Salt air will pit and corrode untreated steel or poorly finished wood. Our powder-coated aluminum finishes are designed to withstand UV exposure and salt spray for decades.

Hardware and Glass Integration

Hardware is where double doors often fail. A single door has one locking point. A double door requires an astragal (the vertical meeting stile), flush bolts, and a multi-point locking system that engages at multiple points along the frame.

We offer full customization on hardware accessories. This includes:

• Multi-point locks with anti-pick cylinders
• Heavy-duty hinges rated for 100 kg+ per leaf
• Concealed or surface-mounted closers
• Floor springs for commercial applications

For glass, we can supply tempered, laminated, or low-E units, pre-installed in the factory. Laminated glass is particularly important for double doors near entry points — it holds together when shattered, providing both safety and security.

The Customization Process: Designing Double Front Doors for Your Project

Every project has unique requirements. We have built our entire business model around accommodating those requirements rather than forcing buyers into standard sizes.

Navigating Custom Sizes and Configurations

Double front doors come in several configurations:

• French double doors: both leaves operable, opening inward or outward
• Double in-swing: both leaves open into the building
• Double out-swing: both leaves open to the exterior — common for commercial and hurricane-prone areas
• One fixed, one operable: one leaf fixed, the other opens — a practical option for high-traffic commercial entries

We offer OEM and ODM services. If you have a specific profile design, we can create custom dies for extrusion. If you have a performance specification, our engineers can calculate the required profile thickness and reinforcement. This level of flexibility is rare among manufacturers, because it requires a factory that controls the entire production process — from raw material to finished product.

Color and Finish Matching

Color matching is a detail that can delay a project by weeks if handled poorly. We maintain a library of standard RAL and wood grain finishes, but we also do custom color matching for large construction projects. Send us a sample, and our finishing team will match it within a reasonable tolerance.

For aluminum doors, we use powder coating with a two-layer application process. For wood doors, we offer a range of stains and clear finishes. We can also do aluminum-clad wood — a wood interior with an aluminum exterior — which combines aesthetics with durability.

Meeting Local Building Codes

This is one of the most critical aspects of sourcing double front doors internationally. Building codes vary dramatically between markets. A door that passes inspection in Texas may not meet the wind load requirements in Miami-Dade County. A door that is code-compliant in Germany may not satisfy the energy rating requirements in Canada.

Our team has extensive experience with international building standards. We adjust the profile structure and fittings to match local building codes of target markets. This includes:

• Wind load calculations based on regional wind speed maps
• Energy performance ratings (U-values, SHGC)
• Safety glass requirements for doors near floors
• Fire rating specifications
• Accessibility standards for commercial buildings

When you send us your project location and local code requirements, our engineers factor those into the design from the start. This reduces the risk of failed inspections on site.

Ensuring Quality and Durability: Our Factory Inspection Process

Quality control is not a single checkpoint — it is a system that runs through the entire production cycle.

Pre-Shipment Testing for Performance

Double doors are particularly prone to air and water leakage if the frame geometry is not precise. The meeting stile between the two leaves is a natural weak point. If the tolerances are off by even 2 millimeters, the door will whistle in the wind and leak in heavy rain.

Our strict pre-shipment inspection includes:

• Air-tightness testing: we pressurize the door assembly and measure air leakage rates per square meter
• Water-tightness testing: we simulate heavy rain conditions and check for water penetration
• Wind resistance testing: we apply static and cyclic pressure loads to verify structural integrity

Every production batch goes through these tests before we issue the packing list. We do not ship products that fail any of these tests.

Material Selection and Craftsmanship

Quality begins with raw materials. For aluminum doors, we use 6063-T5 or 6063-T6 alloy — the same grades used in premium curtain wall systems. For wood doors, we select boards with consistent grain and moisture content.

The craftsmanship details matter too:

• Mortise and tenon joints for wood doors, reinforced with waterproof adhesive
• CNC-machined profile corners for aluminum doors, ensuring precise 45-degree joints
• Welded or mechanical corner joints, depending on the profile design
• Gaskets and seals installed at the factory, not left for site installation

Packaging for International Shipping

A double front door is a large, heavy, and fragile product. Packaging is not an afterthought — it is a critical part of the manufacturing process.

We use reinforced wooden crates with internal bracing to prevent movement during transit. Glass panels are separated with foam and corner protectors. Hardware is packed separately in labeled boxes. Each crate includes a detailed packing list that corresponds to our customs documentation.

We have shipped thousands of doors across oceans. We know what happens to cargo in a container during a rough sea crossing. Our packaging is designed to survive that journey.

Logistics and Supply: Why a Factory Direct Partner Matters

The commercial side of sourcing double front doors is where many buyers get burned. Understanding the logistics and cost structure prevents unpleasant surprises.

Competitive Pricing Without Middlemen

When you buy from a trading company, you are paying for their margin on top of the factory price. That margin can be 15% to 30% or more. When you buy directly from our factory, you eliminate that markup.

We regularly quote projects where our factory-direct price is 20% to 40% lower than what the buyer was quoted through a trading intermediary. The savings can be reinvested in better hardware, upgraded glass, or simply improving the project’s bottom line.

Flexible Shipping: FCL and LCL

We handle both full container loads (FCL) and less-than-container loads (LCL). This flexibility matters for different buyer profiles:

• Importers and distributors ordering large volumes typically prefer FCL — 40-foot or 20-foot containers
• Contractors ordering for a single project may prefer LCL — we can consolidate multiple orders to fill a container
• Developers with phased construction schedules can split orders across multiple shipments

We manage the entire shipping process, from booking the container to delivering to your port of entry. Direct delivery from our China factory means no unnecessary warehousing or handling.

Documentation and Customs Support

International trade runs on paperwork. Missing or incorrect documents can delay a shipment at customs for weeks, incurring storage fees and missed deadlines.

Our foreign trade team provides complete documentation for every order:

• Commercial invoice
• Packing list with detailed weights and dimensions
• Bill of lading
• Certificate of origin
• Any additional certificates required by your destination country

We have experience with markets across the globe, and we understand the specific documentation requirements for each region. This is not our first container — we know what customs officials in your country expect to see.

Frequently Asked Questions

Can you manufacture double front doors with different materials for the interior and exterior?

Yes. Aluminum-clad wood is one of our most requested configurations. The interior face is solid wood veneer for a warm, natural look, while the exterior face is powder-coated aluminum for weather resistance and minimal maintenance. This hybrid approach gives you the best of both materials. We also offer different glass specifications for each leaf if the project requires it.

What is the typical lead time for a bulk order of double front doors?

Lead times depend on the complexity of the order. Standard sizes in aluminum can ship in 25–35 days from order confirmation. Custom solid wood doors typically take 35–50 days because of the drying and finishing processes. For large construction projects, we can prioritize production to meet aggressive schedules. Contact our team with your volume and specification, and we will give you a concrete timeline.

Do you assist with hardware installation, or just supply the door?

We supply doors with all hardware pre-drilled and pre-mounted where possible. This includes hinges, locks, and flush bolts. For commercial projects, we can supply floor springs and automatic opening systems. Each order includes installation guidelines. We also offer technical support via video call if your installation team has questions during the fitting process.

Are your double front doors suitable for hurricane-prone areas?

Yes. Our thermal-break aluminum double doors can be engineered to withstand high wind loads. We perform wind resistance tests on every batch and can adjust the profile structure and glass thickness to meet Miami-Dade County or similar high-velocity hurricane zone requirements. If your project is in a hurricane zone, let us know during the quoting stage so our engineers can factor in the required wind load calculations.

Can I get a sample unit before placing a large order?

Absolutely. We can produce a single sample unit for your approval before mass production. This is common for first-time buyers. We can also arrange a video walkthrough of our production line so you can see the manufacturing process in real time. This verification step protects both sides.
