Custom Wooden Double Doors | Factory-Direct Supply from Jusen

9 min read

The last time we received an inquiry from a distributor in Perth, the first question was not about timber species. It was about whether we could ship 120 sets of double doors in one 40-foot container without a single damaged frame. That question tells you more about the industry than any brochure.

Wooden double doors are heavy. They move. They warp if the moisture content is wrong. They arrive at job sites with scratched finishes if packing is an afterthought. And when they fail on site, the architect does not blame the timber — they blame the factory.

We are Jusen Door and Windows Manufacturing Co., Ltd. We have been building wooden double doors for international projects since before the term “supply chain” became a buzzword. This article explains how our factory handles the three things that actually matter for B2B buyers: engineering, compliance, and logistics.

Why Choose Factory-Direct Wooden Double Doors for Your Project?

Cost Efficiency Without Middleman Markup

When you buy through a trading company, you pay for their office rent, their sales commissions, and their profit margin. That markup often lands between 15% and 30% on top of the ex-factory price. For a project requiring 300 double doors, that difference becomes five figures quickly.

We operate as a direct factory supply source. When you negotiate with us, you are negotiating with the people who own the production lines. Our pricing reflects our actual material costs, labor costs, and overhead — not what a middleman thinks the market will bear. This is why contractors who have worked with both models tend to stay with factory-direct suppliers after their first container.

Engineering Support for Custom Specifications

Here is where many buyers get burned. A wooden double door is not just a wider version of a single door. The weight distribution changes. The hinge load doubles. The frame needs different joinery to prevent sagging over time.

Our engineering support and technical team works directly with your architectural drawings. If your opening is 1,800 mm wide with a 200 mm transom above, we calculate the frame profile, hinge placement, and reinforcement requirements before we cut a single piece of timber. We offer full customization on size, color, glass, and hardware accessories — but customization without engineering input is just guesswork with expensive materials.

Our Manufacturing Capability: From Raw Timber to Finished Double Doors

Advanced Production Lines for Solid Wood and Composite Doors

Our factory floor runs dedicated lines for solid wood doors, thermal-break aluminum doors and windows, system windows, and custom villa doors. The wooden double door line is not an afterthought — it occupies its own space with climate-controlled storage for timber.

The process starts with moisture content verification. Timber that enters our workshop at over 12% moisture will move after installation, no matter how good the finish is. We dry and condition every batch to match the target market’s climate. Then we cut, joint, and laminate the stiles and rails. For double doors, the critical tolerance is at the meeting stile — that center seam where the two doors close. If our CNC machines are off by even 2 mm, you will see light through the gap.

We also manufacture the frames, not just the door slabs. This matters because a pre-hung double door unit installs faster and performs better than a slab-only product. The frame includes the weatherstripping channels, hinge reinforcements, and strike plate housings — all aligned to the door itself.

The Importance of Pre-Shipment Inspection

We do not ship products based on a visual check. Every wooden double door order goes through our strict pre-shipment inspection protocol, which includes air-tightness, water-tightness, and wind resistance tests.

For double doors, the air-tightness test is particularly revealing. The center meeting point between two doors is the weakest seal in any building envelope. We test each pair as an assembled unit, not as individual doors. If the seal fails at 600 Pa, we adjust the weatherstripping or the hardware tension before packing. Wind resistance testing matters more than most buyers realize — a double door on a coastal site faces forces that a single door never encounters.

Customization Options for Wooden Double Doors

Size, Glass, and Hardware Configurations

The standard double door in our catalog starts at 1,400 mm width and goes up to 2,400 mm. But “standard” is just a starting reference. We have built double doors at 3,000 mm width for commercial entranceways, using reinforced steel cores inside the timber frames to handle the load.

Glass options matter as much as the timber. We install double-glazed units with low-E coatings, laminated safety glass, or decorative beveled panels — depending on your project’s security and thermal requirements. Hardware is where we see the most variation. Some markets require multi-point locking systems with panic bars. Others need simple lever handles with mortise locks. We source hardware from certified suppliers and can match specific brand requirements if your specification calls for a particular manufacturer.

Color and Finish Matching

For housing developments, consistency across a large batch is non-negotiable. If unit 12 has a slightly darker finish than unit 45, the homeowner will notice, and the developer will hear about it.

Our finishing line applies stains and lacquers in controlled batches. We maintain color samples from each production run and match them against your approved reference. We offer RAL color matching for painted finishes and custom stain matching for wood grain. Our OEM and ODM services extend to private labeling — if you need your brand applied to the hardware or the packaging, we handle that too.

Navigating International Compliance and Logistics

Adapting to Local Building Codes

Building codes for doors vary significantly by country. European markets often require CE marking and specific fire resistance ratings. North American projects may need compliance with local energy codes that dictate U-values for the entire door assembly. Australia has its own standards for wind load resistance in cyclonic regions.

Our adjustable profile structure and fittings allow us to modify the door construction to match local building codes of your target market. This is not a one-size-fits-all product that we hope passes inspection. We ask about your project location during the quotation stage and engineer accordingly. Fire-rated double doors, for instance, are not simply about thicker timber slabs — the frame, seal, and hardware matter just as much as the door leaf itself.

Documentation and Shipping (FCL & LCL)

Export documentation can sink a project faster than any quality issue. A missing certificate or an incorrectly declared HS code means customs delays, storage fees, and missed installation deadlines.

Our team has rich experience in foreign trade. We provide a packing list, proforma invoice, and full customs documents with every order. For L/C transactions, we prepare the documents exactly as your bank requires. We support both FCL and LCL shipments, with direct delivery from our China factory. For larger projects, we can coordinate partial shipments to match your construction schedule.

Quality Assurance: Our Commitment to Durability

Structural Testing for Heavy Doors

Double doors are heavy. A solid oak pair at 2,200 mm height can weigh over 100 kg. That weight puts stress on hinges, frames, and the floor threshold.

We test our double doors for sagging and warping under load. The test rig suspends the door pair in a frame and applies cyclic opening and closing forces — thousands of cycles — to verify that the hardware and joinery hold up. We also check the squareness of the assembled unit. A door that is out of square by 3 mm will not close properly, and no amount of hardware adjustment will fix it.

Material Selection and Treatment

Timber selection is the foundation of durability. We use kiln-dried hardwoods and engineered wood products that resist moisture damage better than solid timber alone. For external doors, we apply preservative treatments that protect against fungal decay and insect attack.

Our experience with thermal-break aluminum doors and windows and system windows informs how we approach the building envelope. A wooden double door is part of a larger system — the wall, the threshold, and the surrounding glazing all interact. We design our doors with this holistic view, ensuring compatibility with adjacent building components.

A Note on Honest Limitations

Wooden double doors are not always the cheapest option. For high-humidity coastal environments, aluminum or uPVC might outperform timber in terms of maintenance-free longevity. We manufacture those products too, and we will tell you when timber is the wrong choice for your specific site. A factory that only sells one material will not give you that advice. We do, because our reputation depends on your project succeeding — not on a single order.

How to Request a Quote for Your Next Project

Let’s Discuss Your Specifications

Send us your architectural drawings, door schedules, or even a rough sketch with dimensions. Our team reviews each inquiry personally — no automated quoting system that spits out generic prices. We need to know the opening sizes, the number of units, the target climate, and your hardware preferences. The more details you provide, the more accurate our quotation will be.

Supply Chain Partnership

For contractors and developers running multiple projects, we position ourselves as a long-term supply partner, not a one-time vendor. Our construction project bulk supply capability means we can handle consistent replenishment across phases. Our OEM and ODM services allow you to maintain brand consistency across all your projects.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for custom wooden double doors?

We understand that projects vary. While we specialize in bulk supply, our MOQ is flexible depending on the specific size and glass configuration of the wooden double doors. For standard sizes, we can accommodate smaller trial orders. For fully custom designs, a higher MOQ helps justify the tooling and setup costs. Contact our team to discuss your project volume.

Can you manufacture wooden double doors that meet European or North American building standards?

Yes. Our profile structure and fittings are adjustable to match the local building codes of your target market. We have shipped to projects across Europe, North America, Australia, and the Middle East. Share your project location and the relevant standards during the inquiry stage, and we will engineer accordingly.

How do you ensure the quality of the doors before shipping?

Every order goes through our strict pre-shipment inspection, including air-tightness, water-tightness, and wind resistance tests. We test the assembled double door unit — not just the raw materials. This ensures the doors perform correctly upon installation, not just in the factory.

Can you provide a proforma invoice for our letter of credit (L/C) process?

Absolutely. We provide a packing list, proforma invoice, and all necessary customs documents to facilitate a smooth transaction for your import process. Our export team handles the documentation requirements for L/C transactions regularly.

Do you offer private labeling for our brand?

Yes, we offer OEM and ODM services. We can apply your private label, customize the hardware, and match colors to your brand standards. This is a common requirement for distributors who sell under their own brand name.
