When you need an aluminium windows manufacturer that can handle everything from custom design to bulk project delivery, the choice comes down to experience, capability, and trust. At Jusen Doors & Windows Manufacturing Co., Ltd., we have spent 20 years perfecting the art of crafting high-end aluminium windows and solid wood doors for global contractors, interior designers, retail dealers, and villa real estate developers. Our factory in China is not just a production facility—it is a full one-stop OEM & ODM customization hub where every window is built to your exact specifications. Below, we walk you through our capabilities, our processes, and why partnering with us gives you a competitive edge.
Our Company Overview: 20 Years of Aluminium Window Manufacturing Expertise
Since our founding, we at Jusen have focused on two complementary product lines: solid wood entry doors and aluminum alloy windows. This dual expertise has given us a unique understanding of material behavior, structural integrity, and aesthetic harmony. We are not a generalist supplier; we are a specialist manufacturer that has refined our techniques over two decades.
Our core value proposition is simple: we offer complete customization under one roof. Whether you are a contractor sourcing for a luxury villa project, an interior designer specifying a unique window profile, or a retail dealer building your own brand, we provide OEM and ODM services that let you define every detail. Our clients range from single-project buyers to large-scale real estate developers who require consistent quality across hundreds of units.

How does a company with so many years of experience maintain quality? Let’s look inside our factory.
Factory Scale & Production Capability for Custom Aluminium Windows
Our production facility is built for precision and flexibility. We own our entire manufacturing chain, which gives us control that many other aluminium windows manufacturers lack.
Self-Built Processing Workshops for Precision
Within our factory complex, we operate dedicated wood drying, spraying, and aluminum processing workshops. The self-built wood drying workshop ensures that any wooden components (like composite frames or interior trims) are properly conditioned to prevent warping. The spraying workshop applies durable, weather-resistant coatings using advanced electrostatic equipment. And our aluminum processing workshop is where profiles are cut, milled, assembled, and glazed with tight tolerances. This vertical integration means we can monitor every step—from raw material to finished window—without relying on external subcontractors.
Experienced Workforce and Independent Design Team
Our team includes master craftsmen who have been with us for over a decade, plus a dedicated in-house design team. When you send us a custom size or unique design request, our designers create detailed CAD drawings and even suggest improvements based on our 20 years of experience. We have handled everything from ultra-slim frames for contemporary homes to heavy-duty aluminum windows for coastal resorts with high wind loads. This experience translates into fewer prototyping rounds and faster time to market for your projects.
Tailored for Global B2B Partners
Because we control our production schedule, we offer flexible MOQ and competitive lead times—even for complex bulk orders. Many international partners are surprised that a factory with our capacity can accommodate small trial runs before scaling up. That is part of our commitment to building long-term relationships. As one client recently noted, “Jusen’s flexibility allowed us to test five different window designs before placing a container order.” [1]
Advanced Equipment & Aluminum Processing Technology
Quality is not just about skilled hands; it also depends on the machinery we use. Over the years, we have invested in precision cutting lines, automatic corner crimping machines, and multi-axis CNC routers that handle complex profile geometries.
Precision Cutting and Assembly Lines
Aluminum window performance starts with accurate profile cutting. Our saws hold tolerances within ±0.2 mm, ensuring miters fit perfectly. After cutting, profiles move to our automated assembly stations where corner joints are crimped and sealed using structural adhesives. For thermal break windows, we use polyamide strip insertion machines that guarantee consistent insulation performance. We then test every assembled frame for squareness and alignment before glazing.
Surface Treatment and Durability Testing
The finish on an aluminium window determines its lifespan. Our spraying workshop applies powder coating or PVDF finishes to your chosen RAL color. We perform adhesion tests, salt spray tests, and UV resistance checks on every batch to ensure the coating will withstand years of exposure. For projects requiring high energy efficiency, we also offer thermal break profiles and double/triple glazing options. These measures are part of our commitment to meeting international standards like ASTM E1105 and EN 12207. [2]
Engineering Support for Complex Projects
Our technical team goes beyond basic production drawings. For large construction projects, we provide customized construction drawings showing interface details with walls, flashing, and sealing. We also offer structural calculations for wind load resistance, which is especially important for high-rise and commercial applications. This engineering support saves you time and reduces the risk of errors on site.
Annual Capacity & Flexible Supply for Bulk Orders
As a growing manufacturer, we operate multiple production lines dedicated to aluminium windows. Our annual capacity exceeds 50,000 square meters of finished windows, and we continue to expand. This capacity allows us to handle everything from single-unit custom orders to full container loads for housing developments.
Meeting High-Volume Project Deadlines
When you are managing a construction project, delivery delays can cost thousands. We understand that. Our production planning team schedules orders based on realistic lead times, and we communicate proactively if any adjustments are needed. For bulk orders, we maintain dedicated inventory of common aluminum profiles and hardware to reduce waiting time. Many of our clients have told us that our reliability on delivery is one of the main reasons they keep coming back. [3]
North America Overseas Warehouses for Faster Delivery
To serve our North American partners better, we operate overseas warehouses in the United States and Canada. This means we can ship smaller quantities from stock, or consolidate full container orders locally. More importantly, our warehouses serve as a buffer for last-mile delivery and help mitigate shipping damage—a common pain point in international trade. If any damage occurs during transit, our full shipping damage after-sales guarantee ensures you are covered.
Private Label and OEM Flexibility
We support both OEM and private label arrangements. If you want to sell Jusen-manufactured windows under your own brand, we can apply your logo, packaging, and specific compliance markings. We also handle all documentation for customs clearance, making it easy for importers. For retail dealers, this is a great way to offer premium windows without investing in your own factory.
Rigorous Quality Control for Every Aluminium Window
Quality control is embedded in our culture. We follow a multi-stage inspection process that starts with raw material checks and ends with final packaging verification.
In-House Inspection Protocols
When aluminum profiles arrive from our partners, our QC team measures dimensions and checks surface quality. During processing, each work station has a checklist. After assembly, every window undergoes a water tightness test (using spray nozzles at different pressures) and an air leakage test. We also randomly select samples for thermal performance testing. Only windows that pass all checks are approved for packaging.
Stability Through Self-Reliance
Because we own the drying and spraying workshops, we control environmental factors like humidity and dust that affect quality. Many factories outsource these steps, which leads to variation. Our self-reliance ensures that a window produced in January has the same finish and fit as one produced in July. This consistency is critical for large projects where all windows must match perfectly.
After-Sales Guarantee
We stand behind our products. Our full shipping damage after-sales guarantee means that if a window arrives damaged, we will replace it at no cost to you—subject to our terms. This gives our partners peace of mind when ordering thousands of units from across the globe. Combined with our 20-year experience, our guarantee signals that we take quality seriously.
