Factory-Direct Double Door Entry Doors | Custom Sizes & OEM | Jusen

11 min read

When an overseas buyer places their first container order for double door entry doors, the question they ask is rarely about price. It is about whether the factory can replicate the sample quality at scale. That concern is valid. A double door has twice the moving parts, twice the sealing surface, and twice the potential for failure compared to a single leaf.

We have spent over a decade answering that question from our factory floor in China. This guide covers what we have learned about double door entry doors — the engineering, the materials, the customization options, and the procurement process — written for architects, contractors, and distributors who need reliable supply.

Why Double Door Entry Doors Demand More Engineering Than Single Doors

A double door entry door is not just two single doors placed side by side. The center meeting stile, the astragal, the multi-point locking system, and the header support all interact differently under load. When one leaf is active and the other is passive, the passive leaf must absorb wind load and transfer it to the frame without sagging over time.

Aesthetic Impact vs. Structural Integrity

The visual appeal of a grand entrance is obvious. But the structural reality is less glamorous. Double leaves mean a wider unsupported span at the header. If the frame is not reinforced or the profile structure is not designed for it, the doors will begin to droop within a few years. We see this frequently in imported doors that were not engineered for the door’s width-to-height ratio.

Our approach involves an adjustable profile structure. This means the hinges, the frame anchoring, and the meeting stile can be fine-tuned during installation. An adjustable structure allows us to compensate for minor site variations in the rough opening. It also lets us adapt the door’s core to local wind load requirements without redesigning the entire system. For a double door that will see daily use, this adjustability is not a luxury — it is a necessity.

Thermal Performance and Air-Tightness

Here is the imperfect insight: double doors are inherently weaker at thermal performance than single doors. The center seal is a continuous potential leak point. The threshold must bridge two leaves. The hardware penetrations are doubled. No manufacturer can eliminate this entirely. What we can do is minimize it.

We use thermal-break aluminum profiles with polyamide strips. These strips separate the interior and exterior aluminum sections, reducing thermal bridging. The air-tightness of the final product depends on the gasket design and the compression of the multi-point lock. This is why our pre-shipment inspection includes an air-tightness test. We also conduct water-tightness and wind resistance tests on every batch before packing. If a door fails the test, it does not ship.

The B2B Sourcing Challenge

Large door units are awkward to ship. They take up container space, they are heavy, and they are prone to damage if packed improperly. Finding a supplier who understands export logistics is as important as finding one who can weld a good frame. Our foreign trade team has handled FCL and LCL shipments for years. We know how to brace doors inside a container to prevent shifting. We also provide the full customs documentation — packing lists, proforma invoices, and certificates of origin — so your clearance process does not stall.

Core Materials We Manufacture for Double Door Entry Doors

The material choice dictates the door’s lifespan, maintenance needs, and aesthetic direction. We produce three primary types of double door entry doors in our factory.

Thermal-Break Aluminum Double Doors

This is our most requested product line for exterior applications. Thermal-break aluminum offers a strength-to-weight ratio that solid wood cannot match. The polyamide strips reduce condensation on the interior frame surface in cold climates. The aluminum surface accepts powder coating in any RAL color. We also apply wood-grain transfer for projects that want the look of timber without the maintenance.

The profile thickness we use varies from 1.4mm to 2.0mm depending on the door’s size and the local wind load requirements. For a double door that is 1800mm wide and 2400mm tall, we typically use a reinforced profile with a steel core insert in the active leaf. This prevents torsion when the door is opened and closed repeatedly.

Solid Wood and Engineered Wood Options

Solid wood double doors remain the choice for high-end villa projects and heritage-style buildings. We work with oak, mahogany, walnut, and engineered wood composites. The trade-off with solid wood is clear: it requires ongoing maintenance. It expands and contracts with humidity. For interior applications or protected exterior entries, it is unmatched in appearance.

Our OEM and ODM services apply here as well. You specify the wood species, the veneer cut, the carving details, and the finish. We produce to your drawings. We have done doors with hand-carved panels for Middle East palaces and minimalist flush-oak doors for Scandinavian-style villas. The same factory line handles both.

Aluminum Alloy Entrance Doors (Hybrid Solutions)

Some projects need the best of both worlds. An aluminum alloy entrance door with a timber interior face or an aluminum-clad wood door offers the durability of metal outside and the warmth of wood inside. These hybrid systems are more expensive to produce, but they eliminate the maintenance cycle of exterior wood. We recommend them for coastal environments where salt air corrodes standard hardware and finishes.

Customization Capabilities for Double Door Entry Doors

B2B buyers do not need standard products. They need products that fit the drawings. Our entire production process is built around customization.

Size and Configuration Flexibility

Double doors can be configured in several ways. Equal panels — both leaves the same width — are the most common. But we also produce a one-and-a-half configuration where one leaf is fixed and the other is active. This is useful for entryways where the opening width is tight or where you want a wider passive panel for natural light.

We build to your exact dimensions. There is no standard size we force you into. Send us your rough opening measurements, and we will design the frame and leaves to fit. This is particularly important for renovation projects where the existing opening is not square.

Glass, Color, and Hardware Options

The glass specification is a critical decision. We offer Low-E insulated glass for energy efficiency, tempered safety glass for code compliance, and laminated glass for security. Decorative grids, frosted patterns, and custom muntin bars are available. We also handle curved or arched glass for special entryways.

Color matching is done via powder coating or anodizing. We can match RAL, Pantone, or a physical sample you send us. Wood-grain foil can be applied to aluminum profiles to match adjacent timber elements. Hardware is fully customizable as well — multipoint locks, concealed hinges, floor springs, and smart locks from brands like Hoppe, VBH, or Chinese equivalents with equivalent quality standards.

OEM and Private Label Manufacturing

Many of our clients are distributors who sell under their own brand. Our private label service handles this cleanly. We apply your logo to the hardware, the glass, and the packaging. We do not compete with you in your market. Our role is to manufacture, test, and ship. You brand, market, and sell. This arrangement has built long-term relationships with distributors across Europe, North America, and the Middle East.

Engineering Support and Compliance

Architects and contractors need technical documentation. We provide it.

Meeting International Building Codes

Building codes vary significantly by region. Wind load requirements in Florida are different from those in Germany. Safety glass regulations differ. Our adjustable profile structure and fittings allow us to modify the door’s core structure to meet your local codes. We do not offer a one-size-fits-all product. We ask about your project location and the applicable standards before we finalize the design.

The Role of Pre-Shipment Testing

We test every batch. The tests we run — air-tightness, water-tightness, and wind resistance — are not optional extras. They are part of our standard quality control process. The test equipment is on our factory floor, and the results are recorded and available to you upon request. If your project requires third-party certification, we can coordinate with inspection agencies like SGS or TÜV for an additional fee. This gives you documented proof that the doors meet the specified performance levels.

Technical Drawings and Documentation

You will receive shop drawings for approval before production begins. After production, you receive the final as-built drawings, installation manuals, and maintenance guides. Our foreign trade experience means we know what documents your customs broker will ask for. We prepare them in advance. This includes the commercial invoice, packing list, bill of lading, and any certificates of origin.

The Jusen Factory Advantage in Sourcing and Logistics

The factory-direct model is not just about price. It is about control.

When you buy from us, you pay for the materials, the labor, the factory overhead, and a reasonable margin. You do not pay for a trading company’s markup. This direct supply model lets us offer competitive pricing on bulk orders without compromising on material quality. The savings show up in your project budget.

Global Shipping and Export Documentation

We arrange shipping for both FCL and LCL shipments. For LCL, we pack the doors carefully to fit the shared container. For FCL, we load the entire container with your order and brace it properly. We have shipped to over 40 countries. Our team handles the export customs clearance on the Chinese side. You handle the import clearance on your side, with our documents supporting the process.

Quality Assurance Before Dispatch

Every double door entry door is tested for air and water tightness before it is packed. After testing, we wrap the door in protective film, add edge protectors, and secure it in a wooden crate. The crate is designed for the specific container size to minimize movement during transit. We have seen the damage that occurs when doors are packed loosely. We do not repeat those mistakes.

Frequently Asked Questions

What is the standard size for a double door entry door?

There is no universal standard. Residential double doors commonly range from 1200mm to 1800mm in total width. Commercial entries can be wider. We recommend custom sizing to your specific rough opening. As a manufacturer, we can produce double doors up to 2500mm wide and 3000mm tall in aluminum. Solid wood doors have a slightly lower maximum width due to weight and stability limitations.

Are aluminum double doors better than wood?

For exterior use, yes — aluminum offers superior durability, minimal maintenance, and better thermal performance when using thermal-break profiles. Wood is more susceptible to warping and requires periodic refinishing. For interior doors, wood is often preferred for its appearance. The right choice depends on your project’s climate, style, and maintenance budget.

Can you match custom colors like RAL or wood grain?

Yes. We use powder coating for RAL colors and wood-grain transfer for timber-look finishes. Anodized finishes are also available. Send us a sample or a color code, and we will match it. We keep a library of standard wood-grain foils, but custom patterns can be sourced on request.

What is your MOQ?

Our MOQ is flexible. We handle large construction projects with hundreds of doors. We also work with smaller distributors who are just starting. The MOQ depends on the product type and the level of customization. Contact us with your project volume, and we will give you a clear answer. We do not turn away serious buyers because their first order is small.

How do you ensure the doors are not damaged during shipping?

Heavy-duty export packaging is standard. Each door is wrapped in protective film, fitted with corner protectors, and placed in a wooden crate. The crate design accounts for the container size to prevent shifting. We have shipped thousands of doors without transit damage claims. Our packing method is refined to prevent the most common issues: scratching, denting, and moisture ingress.

Can you manufacture doors with fire ratings?

We can produce fire-rated aluminum and steel composite doors. Fire-rated doors are not simply about thicker slabs. The frame, seal, and hardware matter just as much. If your project requires a fire rating, let us know the standard you need to meet (e.g., BS 476, EN 1634, UL 10C) and the rating duration. We will advise on the system that fits your requirements.

Decision Guide: Choose the Right Double Door Entry Door

Choose thermal-break aluminum if your project is exterior, exposed to weather, or located in a region with extreme temperature swings. It requires minimal maintenance and offers the best long-term thermal performance.

Choose solid wood if the door is for an interior application, a protected exterior entry, or a heritage project where appearance is the priority and the client accepts routine maintenance.

Choose a hybrid aluminum-clad system if you need the durability of metal for an exterior door but the visual warmth of wood on the interior face. This is the premium option for coastal or high-humidity environments.

Choose our OEM or private label service if you are a distributor who wants to sell these doors under your own brand. We handle the manufacturing, testing, and shipping. You handle the marketing and sales.

The right double door entry door is not the most expensive one. It is the one that fits your climate, your building code, and your client’s aesthetic expectations. We produce all three types, and we can guide you to the right specification based on your project details.

Send us your drawings or your rough opening dimensions. Our team will review the requirements and come back with a technical proposal and a quote. We will tell you if your design has structural issues before you commit to it. That is the value of working with a factory that understands the product from the inside out.
