8 Foot French Doors Exterior | Factory Direct Wholesale | Jusen

9 min read

When a developer in Calgary asks us to quote 300 units of 8-foot French doors, the first question is never about price. It is about whether the door will stay square after two harsh winters. We have shipped these tall configurations for over a decade, and the engineering that goes into preventing sag and air leakage is what separates a factory that understands large-format doors from one that simply assembles them.

This article is written for procurement managers, architects, and contractors who need a dependable supply partner for 8-foot exterior French doors. We will walk you through our manufacturing process, customization options, pricing structure, and logistics — from our factory floor in China to your job site.

Why a Factory-Direct Partner Matters for 8-Foot French Doors

An 8-foot door panel is heavy. A standard 80-inch door weighs roughly 60–80 pounds depending on material; an 8-foot version can easily exceed 120 pounds with double glazing. That extra mass creates problems if the internal reinforcement is not designed correctly.

Our engineering team adjusts the profile structure specifically for tall panels. For aluminum doors, we increase the wall thickness of the main frame to 2.0mm and add a steel-reinforced core inside the active leaf. This prevents the door from twisting during daily use — a failure mode we have seen in imported doors that were not engineered for this height.

Every batch we produce undergoes pre-shipment testing for air-tightness, water-tightness, and wind resistance. These are not random checks. We run them on a dedicated test rig in our factory, and the results are documented for each production lot. If a door fails the air-infiltration test at 600 Pa, it does not ship. That is our rule.

Buying direct from our factory also removes the distributor markup. When you source through a trading company or a local importer, you are paying for an extra layer of handling, warehousing, and profit. We quote you the price we need to manufacture, test, and pack the doors. Nothing more.

Our Range of 8-Foot French Door Configurations

Not every project needs the same door. A coastal villa in Florida has different requirements than a mountain retreat in Colorado. We manufacture both thermal-break aluminum and solid wood configurations, and we customize each one to the project’s specifications.

Thermal-Break Aluminum 8-Foot French Doors

Our thermal-break aluminum series uses polyamide strips to separate the interior and exterior aluminum profiles. This is the right choice for projects that must meet strict energy codes like Title 24 in California or the Passive House standard. We offer both 24mm and 34mm thermal-break widths, and the glazing can be specified as double or triple pane with low-E coatings and argon gas fill.

Solid Wood and Clad-Wood 8-Foot French Doors

For luxury villa projects where aesthetics are the priority, our solid wood line includes oak, mahogany, and sapele. We source the timber from FSC-certified suppliers and kiln-dry it to a moisture content of 10–12% before machining. This is critical — wood that is not properly dried will warp after installation.

We also offer clad-wood options where the exterior is aluminum and the interior is wood. This gives you the low-maintenance exterior and the warm interior finish, but it costs more than either single-material option. It is not always the right call for every budget, and we will tell you that honestly when we quote.

Custom Glass and Hardware Integration

Full customization is not a buzzword for us. We adjust the glass thickness based on your wind-load requirements, change the frame color to match your architectural drawings (we stock over 200 RAL colors), and fit hardware from brands like Hoppe, Siegenia, and Kinlong based on your preference.

For 8-foot doors, we strongly recommend a multi-point locking system. A tall door can bow slightly at the middle, and a single-point lock will not pull the door tight enough against the gasket. Our standard configuration for these doors includes a 16-point locking mechanism that secures the door at every 12 inches along the height.

OEM, ODM, and Bulk Supply for Large-Scale Projects

Construction companies and developers need more than a product. They need a manufacturing partner who can produce to their brand standards, meet project deadlines, and handle the paperwork of international trade.

Our OEM service means we produce doors under your brand name. We can apply your logo, use your specified hardware, and pack the doors with your installation manual. For ODM projects, we adapt our existing designs to fit your unique specifications — whether that means a different frame profile, a custom threshold height, or a specific glazing package.

We handle construction project bulk supply routinely. A typical order from a hotel developer in the Middle East might be 500–800 units across multiple door sizes. We schedule production in phases so that the first shipment goes out while the remaining units are still being manufactured. This keeps your construction timeline moving.

One of the most common concerns we hear from importers is about building code compliance. Our profiles and fittings are adjustable to match local building codes in North America and Europe. For example, we can fit doors with ADA-compliant thresholds, hurricane-rated glass for Florida, or security-rated hardware for commercial applications. We need your local code requirements at the quoting stage, and we will engineer the door to pass.

Competitive Pricing and Transparent Cost Breakdown

We will be direct: our factory-direct pricing is typically 15–25% lower than buying through a trading company, depending on the configuration and volume. That savings comes from removing the middleman, not from cutting material quality.

When you request a quote, we provide a line-item breakdown. You see the cost of the profiles, the glass, the hardware, the packaging, and the freight separately. No hidden charges, no surprises at the invoice stage.

Our engineering team can also suggest value engineering options. For example, if your project budget is tight, we might recommend a thermal-break aluminum door with a wood-grain foil finish instead of a solid wood door. It gives you the same visual effect at roughly half the cost. It is not the same product — the wood grain is printed, not real — but for many projects, the trade-off is worth it.

Our minimum order quantity is flexible. We accept orders as small as one set of doors for a custom villa project, and we scale up to hundreds of units for large developments. The pricing structure differs — smaller orders pay a higher per-unit cost due to setup and customization — but we never turn away a serious buyer.

Global Logistics: FCL, LCL, and Documentation

International shipping is where many first-time importers get nervous. We handle this in-house, and our foreign trade team has over a decade of experience moving doors to North America, Europe, Australia, and the Middle East.

We ship both FCL (Full Container Load) and LCL (Less than Container Load). For large orders, FCL is almost always more cost-effective. For smaller orders or sample orders, LCL allows you to share a container with other buyers and pay only for the space your goods occupy.

Every 8-foot door is professionally crated for transit. We use a wooden frame with foam padding at all contact points, and the glass is protected with a PE film that is removed after installation. We have tested our packaging with third-party drop tests, and the damage rate in transit is under 0.5%.

Our export documentation package includes the packing list, proforma invoice, bill of lading, and full customs documents. We also provide the Certificate of Origin and, for certain markets, the necessary test reports for thermal performance and safety glass certification.

After-Sales Support and Technical Assistance

A supplier relationship does not end at the port. We provide technical support through the installation phase and beyond.

Our installation team is available by video call to walk your crew through the hanging process for 8-foot doors. This is not a standard installation — the weight of the door requires proper shimming and adjustment of the hinges to ensure a consistent gap around the perimeter.

We also provide guidance on adjusting the fittings over time. Tall doors need periodic hinge adjustment to maintain their seal. We send a maintenance guide with every order, and our technical team answers questions via email or WhatsApp within one business day.

The time zone difference between China and Western markets is real. We schedule our support team to cover overlapping hours with North American and European clients, so you are not waiting until the next morning for an answer.

Frequently Asked Questions

Can you manufacture 8-foot french doors with a specific R-value for cold climates?

Yes. We customize the thermal-break profile and use double or triple glazing to meet specific energy performance requirements. For very cold climates, we recommend a triple-glazed unit with two low-E coatings and argon gas fill, which achieves a U-factor of approximately 0.20 Btu/h·ft²·°F.

What is the typical lead time for a bulk order of 8-foot exterior french doors?

Lead time depends on volume and customization level. Standard configurations with our stock profiles run 4–6 weeks from order confirmation. Fully custom projects with unique profiles or special glass can take 8–10 weeks. We provide a production schedule with your quotation, and we update you weekly during manufacturing.

Do you provide the necessary documentation for import into the USA or Europe?

Yes. Our foreign trade team provides all necessary packing lists, proforma invoices, bills of lading, and customs documents. We also supply test reports for glass certification (ANSI Z97.1 for the US, EN 12150 for Europe) and thermal performance data when required.

Are these doors available with a multi-point locking system for security?

Absolutely. We offer multi-point locks from Siegenia and Hoppe as standard options for 8-foot doors. The 16-point locking mechanism secures the door at regular intervals along the height, which is essential for tall doors to maintain a consistent seal and resist forced entry.

Can we order just one set of doors for a single luxury home project?

Yes. While we specialize in bulk supply, we also cater to custom villa projects and can fulfill single-unit orders with full customization. The per-unit price will be higher than a bulk order, but the quality and engineering are identical.

How to Choose the Right Configuration

If your project is in a climate with extreme temperature swings — think Minnesota, Alberta, or Scandinavia — choose the thermal-break aluminum door with triple glazing. The energy savings over the building’s life will offset the initial cost.

If the project is a high-end residential villa where the entrance is a design statement, choose the solid wood or clad-wood option. The natural grain and warmth of the wood cannot be matched by aluminum, and your clients will notice the difference.

Choose the 8-foot French door configuration from our standard range if your project timeline is tight. If you need a fully custom profile, unique dimensions, or special hardware, the ODM route gives you design freedom but requires a longer lead time.

And if you are unsure, send us your drawings. Our engineering team will review them and recommend a configuration that balances performance, aesthetics, and budget.
