How We Engineer High-Performance Aluminum Fixed Windows for Global Projects
At Jusen Doors & Windows Manufacturing Co., Ltd., we understand that aluminum fixed windows are more than just stationary panes — they are critical architectural elements that define a building’s energy performance, aesthetic clarity, and structural integrity. As a professional manufacturer with over 20 years of experience in both solid wood doors and aluminum window production, we engineer our aluminum fixed windows to meet the rigorous demands of modern construction projects worldwide.
Our fixed windows are designed for seamless integration into curtain walls, commercial facades, and luxury villas. We supply these to global contractors, interior designers, retail dealers, and villa real estate developers — providing everything from custom size and design to private labeling and bulk project supply. When you partner with us, you’re not just buying a product; you’re accessing a full one-stop OEM & ODM customization service backed by our self-owned workshops, independent design team, and North America overseas warehouses.
Why Architects and Developers Choose Our Aluminum Fixed Windows
Our fixed windows are a preferred choice for B2B clients because we address the three core demands of any serious project: design flexibility, structural stability, and energy efficiency. We don’t build generic frames — we build solutions.
Seamless Integration with Modern Facades
Our aluminum fixed windows accommodate large glass panels and ultra-clean sightlines, making them ideal for minimalist architecture. Our independent design team works directly with your architectural drawings to ensure our profiles integrate perfectly with your facade system, whether you need slim-frame profiles or reinforced structural sections.
Superior Thermal and Acoustic Performance
Every frame we produce uses multi-chamber profiles and polyamide thermal break strips to minimize heat transfer. Because we operate our own aluminum processing workshop, we control the precision of every cut and assembly. Additionally, our North America overseas warehouses allow us to pre-test profiles against regional thermal and acoustic standards, ensuring your project meets local building codes without delivery delays.
We rely on 20 years of material processing knowledge to select the right alloy and coating for your climate zone — from coastal salt resistance to high-altitude UV exposure.
Full Customization Through Our OEM & ODM Aluminum Window Service
One of the most common questions we receive from architects and dealers is: Can you produce aluminum fixed windows in non-standard sizes? The answer is yes — and we go far beyond simple size adjustments.
Custom Sizes, Profiles, and Glass Configurations
Our factory supports full personalized customization. We can produce fixed windows with custom widths, heights, profile depths, and glass thicknesses. Whether you need a 6-meter fixed pane for a lobby or a narrow mullion system for a residential villa, we have the tooling and experience to deliver.
We also match specific RAL colors, anodized finishes, and even wood-grain textures that coordinate with our solid wood door lines — a unique capability among aluminum window manufacturers.
Private Label and Bulk Project Supply
For retail dealers and developers, we offer private label services. We can place your brand on the hardware, frame surfaces, and packaging. Our construction project bulk supply capability ensures consistent quality across hundreds or thousands of units. Best of all, we maintain flexible MOQ — so whether you need 10 windows for a small villa or 1,000 units for a housing development, we can accommodate your timeline.
Our self-built aluminum processing workshop enables rapid prototype turnaround and production ramp-up, which directly supports both small test orders and large-scale rollouts.
Our Production Capacity and Technical Infrastructure
To serve global B2B clients with confidence, we invest heavily in our physical manufacturing infrastructure. We don’t outsource critical processes — we control them in-house.
In-House Aluminum Workshop and Precision Machining
Our dedicated aluminum workshop is equipped with CNC machining centers, double-head cutting saws, corner crimping machines, and automatic assembly lines. This allows us to hold tight tolerances (±0.5 mm on profile lengths) and produce complex geometries such as sloped adapters or integrated drainage channels.
Because all machining happens under one roof, we reduce lead times and eliminate coordination errors between subcontractors.
Skilled Workforce and Efficient Production Lines
Our annual production capacity reaches tens of thousands of aluminum window units. This throughput is possible because of our experienced workforce — many of our technicians have been with us for over a decade. We also benefit from our self-built wood drying and spraying workshops, which allow cross-departmental knowledge sharing on finishing, sealing, and assembly techniques.
This integrated factory model directly supports short lead times — typically 15 to 30 days for custom orders — without sacrificing build quality.
How We Ensure Quality Control for Every Aluminum Fixed Window
Quality is not a department at our factory — it is a process embedded in every step of production.
Rigorous Testing for Water Tightness and Structural Integrity
Every batch of fixed windows undergoes a battery of in-house tests: water spray testing to simulate heavy rain, air infiltration checks under pressure differentials, and load-bearing tests for wind resistance. These tests are performed on randomly selected units from each production lot.
We back this up with our full shipping damage after-sales guarantee. If a window arrives damaged due to packaging failure, we replace it at our cost. This guarantee reflects the care we put into our packaging standards, which include corner protectors, foam inserts, and reinforced crating for sea freight.
Traceability and Consistent Production Standards
Each order is assigned a batch number that traces back to specific raw material lots, machine operators, and QC checkpoints. This traceability ensures we can quickly identify and correct any deviation — and it gives our clients full confidence in batch-to-batch consistency.
Our 20 years of experience in both solid wood and aluminum processing gives us an edge in understanding how materials react under different conditions. For example, we know exactly how aluminum extrusions behave during anodizing versus powder coating, and we adjust our processes accordingly.
Our self-built spraying workshop applies durable, uniform finishes that meet international standards for UV resistance and adhesion.
Engineering Support: We Help You From Drawing to Delivery
We position ourselves as a technical partner, not just a vendor. When you work with us, you gain access to a full engineering team that can solve installation challenges before they become site problems.
Customized Construction Drawings in 24 Hours
Within one business day of receiving your inquiry, our team provides customized construction drawings and a formal quotation. These drawings show exact dimensions, profile cross-sections, interface details with adjacent structures, and hardware placement. This rapid turnaround allows your team to proceed with procurement without waiting weeks for information.
Sourcing and Compatibility Assistance
Because we also manufacture timber door frames and supporting hardware accessories, we can help you coordinate the relationship between fixed windows and entry doors for a unified project aesthetic. For example, if your project requires matching aluminum fixed windows with solid wood entry doors from our line, we can align colors, sightlines, and hardware styles to create a coherent design language.
Our independent design team is experienced in solving on-site challenges such as out-of-square openings, limited anchor points, or unusual glass weights.
Logistics and Global Reach: Supplying North America, Europe, and Beyond
Logistical confidence is often a deciding factor for B2B buyers. Here is how we ensure smooth delivery across borders.
North America Overseas Warehouse and Global Shipping
We maintain overseas warehouses in North America that stock popular profiles and components. This allows us to fulfill regional orders faster and reduce freight costs compared to direct factory-to-site shipping from China. For projects in Europe, Asia, and the Middle East, we have established relationships with major freight forwarders and experience with international packaging standards.
Every shipment is packed with our zero-damage packaging protocol, which includes plywood crating, internal bracing, and desiccant bags for moisture control.
Flexible MOQ and Bulk Order Handling
We welcome both small custom batches and large construction project orders. Our flexible MOQ means you can start with a test order of a few units, verify quality, and then scale up to hundreds of units for the next phase. We have repeatedly delivered stable quality across multi-phase projects, earning repeat business from global distributors and project partners.
New distributors and project partners are warmly welcomed — we provide dedicated account management and design support for every new collaboration.
