Custom Double Doors Front Manufacturer | Factory Direct | Jusen

10 min read

The email arrived at 9:47 PM from a developer in Perth. He had attached three photos of a two-story villa under construction. His question was straightforward: “Can you make these double doors front units with a 2.4-meter height and an unequal split? And what is your real lead time?”

That question — the mix of dimensions, configuration, and timeline — is the actual conversation B2B buyers need to have with a factory. Not a brochure download. Not a catalog flip-through. The front door of a building carries the visual weight of the entire facade. When it is a double door, the stakes double: the span is wider, the hardware loads are heavier, and the air-seal line is longer. Get it wrong, and the building leaks heat, noise, and reputation.

At Jusen Door and Windows Manufacturing Co., Ltd., we build these systems every day. Our factory floor in China runs thermal-break aluminum lines and solid wood workstations under one roof. This article walks through what actually matters when sourcing double doors front systems — material selection, customization limits, factory testing, and the financial logic of buying direct.

Why Choose Aluminum or Wood for Your Double Doors Front?

The material decision for double front doors is not an aesthetic preference. It is a structural calculation with aesthetic consequences.

The Thermal-Break Aluminum Advantage

A double door spans roughly 1.8 to 2.4 meters of clear opening. That width creates leverage on every hinge and every lock point. Standard aluminum profiles flex under that load. Our thermal-break aluminum profiles do not, because the polyamide strips separate the interior and exterior metal surfaces, adding rigidity while stopping thermal transfer [1].

The insulation benefit matters more than most buyers expect. A double door has a longer perimeter seal than a single door — approximately 20-30% more edge length where air can escape. If the profile is not thermally broken, that edge becomes a thermal bridge. Our factory tests these assemblies for air-tightness according to GB/T 7106 standards, and the results consistently show why thermal-break construction is non-negotiable for energy-rated projects [2].

The Prestige of Solid Wood

For luxury villa projects, nothing replaces the visual weight of solid wood. We manufacture custom solid wood doors using kiln-dried hardwoods with a moisture content stabilized between 8-12%. The drying process matters — wood that ships with excess moisture will warp within months of installation in a different climate. We have seen this failure mode in imported doors that skipped proper conditioning.

Wooden doors are not always the cheapest option. For high-humidity coastal areas, buyers should prioritize the aluminum system over appearance. Wood demands maintenance; aluminum does not. That trade-off is yours to make, but we will tell you honestly which material fits your climate before we take your order.

Matching Materials to Project Needs

Our sales engineers ask three questions before recommending a material: What is the local climate? What is the building’s architectural style? What is the wind load rating required by local code? The answers point to aluminum, wood, or a hybrid system. We produce both, so the recommendation is based on your project, not our inventory.

Customization Options for Your Double Doors Front

Standard catalogs are the enemy of distinctive architecture. Our OEM and ODM services exist because no two projects share identical opening dimensions, traffic patterns, or design languages.

Sizing and Configuration Flexibility

A “double doors front” does not have to mean two equal halves. We routinely produce unequal splits — 1/3 and 2/3 configurations — that allow one leaf to handle daily pedestrian traffic while the wider leaf opens for furniture or equipment moves. Our full customization on size includes height extensions up to 3.2 meters for grand entryways, which requires deeper profile sections to maintain structural integrity.

Our adjustable profile structure also matters for code compliance. Egress width requirements, fire exit regulations, and accessibility standards vary by jurisdiction. We adapt the frame geometry and hardware positions to meet the specific codes of your target market, whether that is AS2047 in Australia, NFRC in North America, or EN 14351-1 in Europe [3].

Glass and Hardware Integration

Double doors front units need glass that balances light transmission with security. We offer double glazing, laminated safety glass, frosted privacy options, and decorative inserts. For hardware, the selection is broader than most buyers expect: multi-point locking systems with 5-7 locking points, concealed hinges that hide the pivot mechanism, and smart lock integration for access control systems.

We are not limited to standard catalogs. If your project specifies a particular hardware brand — or requires powder coating in a specific RAL color — we source it. Our supply chain relationships allow us to match hardware finishes to the door frame, the building’s window system, or a brand standard you need to maintain across multiple projects.

Color and Finish Matching

Color consistency across a building facade is a detail that clients notice. Our powder coating line can match any RAL color, and our wood finishing team can replicate specific stains and grains. When you order double doors front units alongside matching windows and sliding doors, everything ships with identical finishes.

Our Factory Process: From Raw Material to Finished Double Door

The difference between a door that lasts five years and one that lasts twenty is not the brand name on the hardware. It is what happens inside the factory before the door is crated.

Precision Cutting and Assembly

Our production line starts with aluminum profiles that are cut to exact lengths using CNC machining centers. The tolerance on these cuts is ±0.5mm. That precision matters because a double door has two leaves that must align perfectly at the meeting stile. If the frame is out of square by even a few millimeters, the door will bind, the seal will gap, and the hardware will wear unevenly.

Assembly follows a documented sequence: frame construction, glazing bead installation, hardware mounting, and weather-strip fitting. Each station has a checklist. Each door is numbered and tracked through the process. This traceability is what allows us to stand behind our strict pre-shipment inspection protocol.

Performance Testing (Air, Water, Wind)

We do not ship doors based on visual inspection alone. Every batch of double doors front units undergoes air-tightness, water-tightness, and wind resistance tests before leaving the factory. The test chamber applies differential pressure to simulate wind loads, sprays water at specified rates to check for leaks, and measures air infiltration through the assembly [2].

This testing is your protection against installation callbacks. A door that fails a water test on site costs you labor hours, material rework, and client trust. A door that passed our tests before shipping has a much higher probability of passing yours.

Packaging for Export

Export packaging is an engineering task, not an afterthought. Our crates use plywood frames with internal bracing that prevents movement during container transit. Each door is wrapped in protective film, and hardware is packed separately in labeled boxes. With our rich experience in foreign trade, we have refined these procedures to minimize damage claims — typically below 0.5% across our shipments.

The Financial Advantage of Sourcing Direct from Our Factory

The biggest line item in your procurement budget for double doors front is not the material. It is the markup you pay to intermediaries.

Eliminating the Middleman

When you buy from a trading company, you pay for their office overhead, their sales commissions, and their profit margin — typically 20-30% on top of the factory price. Buying direct from our factory eliminates that layer entirely. The price we quote is the price we manufacture to. There is no hidden markup between our production line and your shipping port.

Competitive Pricing for Bulk Orders

For construction project bulk supply, the unit price drops as the order volume increases. We structure quotes with tiered pricing based on quantity. A 100-unit order for a residential development earns a significantly better per-door price than a 10-unit order for a boutique hotel. Our sales team is transparent about these tiers — we want your repeat business, not a one-time transaction.

Transparent Proforma Invoicing

We provide a packing list, proforma invoice, and full customs documents with every order. These documents are accurate and complete, which means your customs broker will not face surprises at the port of entry. No unexpected duties. No delays from missing paperwork. This administrative reliability is part of our foreign trade expertise.

Logistics and Global Shipping

Getting the doors built is half the challenge. Getting them to your site intact and on time is the other half.

Flexible Shipping (FCL & LCL)

We offer both FCL (Full Container Load) for large orders and LCL (Less than Container Load) for smaller projects or prototype samples. Direct delivery from our China factory means no consolidation warehouse delays — your cargo is loaded at our facility and moves straight to the port. For urgent requirements, we also coordinate air freight for sample units.

Compliance with Local Building Codes

Our engineering team reviews the building codes of your target market before we finalize production drawings. If your project requires hurricane-rated doors for Florida, we adjust the profile wall thickness and hardware specifications accordingly. If your market requires specific energy performance ratings, we select the appropriate glass and thermal-break components [3]. This proactive approach prevents costly redesigns after shipment.

Timely Production Scheduling

Lead time is a function of order complexity and current production load. Standard double doors front units typically ship within 25-35 days of confirmed order. Custom designs with unique extrusions or specialty glass may require 45-60 days. We provide a production schedule with your order confirmation and update you at each milestone.

Frequently Asked Questions (FAQs)

Q1: What is the maximum size for your double doors front?

Our engineering team can customize sizes based on structural calculations for our thermal-break profiles. Generally, we produce double doors up to 3.2 meters wide and 3.0 meters high. For larger spans, we recommend a fixed sidelight panel beside the operable leaves to maintain structural stability. Contact us with your specific opening dimensions for a structural assessment.

Q2: Can you provide samples before a bulk order?

Yes, we support both OEM and ODM. We can produce a sample unit for your approval before committing to a full container order. Samples are typically shipped via LCL or air freight. The sample cost is credited against the bulk order once confirmed.

Q3: Do you provide installation drawings?

Every order includes detailed installation drawings and technical documentation. While we do not send installation crews overseas, our technical team is available for video consultations to guide your installers through the process. We have done this for projects in Australia, the Middle East, and North America — it works well when your team follows the drawings.

Q4: How do you ensure the doors pass local weather resistance tests?

Our factory conducts rigorous air-tightness, water-tightness, and wind resistance tests before shipment. We adjust the profile structure and gasket specifications to meet the performance criteria of your local codes. We have passed AS2047 testing for Australian projects and are familiar with the test requirements across major markets [2].

Q5: What is your MOQ for custom designs?

MOQ depends on design complexity and materials. For standard sizes, we are flexible — even a single container works. For fully custom extrusions requiring new tooling, a larger order is necessary to amortize the mold costs. Contact Our Team with your project volume and we will provide a clear answer.

The Buying Decision: What Matters Most for Your Double Doors Front Project

You have three paths forward for your double doors front procurement:

Choose factory-direct sourcing if your project has clear specifications, you need competitive pricing on volume, and you want a single point of accountability for quality and delivery. This is the most cost-effective route for professional buyers.

Choose a local distributor if you need immediate local stock, minimal lead time, or on-site technical support for every unit. The price premium is the cost of that convenience.

Choose a trading company only if you cannot find a factory that matches your customization requirements. Even then, verify their manufacturing relationships — many trading companies do not own production facilities and cannot guarantee quality control.

For most B2B buyers, the direct factory route with Jusen offers the best balance of price, customization, and quality assurance. Our doors carry the performance testing documentation you need, our pricing reflects factory efficiency, and our team speaks the language of construction specifications.

The villa in Perth got its doors — the developer sent photos after installation. The aluminum frames sat flush, the unequal split worked exactly as designed, and the client approved the finish on the first walkthrough. That is the outcome we manufacture for.
