Trusted System Windows Manufacturer – Custom Aluminum & Wood Solutions for Global B2B Partners
When general contractors, interior designers, and villa developers search for a system windows manufacturer, they are not just looking for a supplier of frames and glass. They are looking for a production partner who can deliver precision-engineered windows and doors that meet specific project requirements, tight deadlines, and rigorous performance standards. At Jusen Doors & Windows Manufacturing Co., Ltd., we have been filling that role for two decades.
Our company owns a complete ecosystem of production resources: self-built wood drying and spraying workshops, a dedicated aluminum processing facility, an independent design engineering team, and overseas warehouses in North America. This vertical integration means that every system window we ship — whether it is a thermally broken casement for a high-rise residential tower or a custom tilt-and-turn unit for a luxury villa — is designed, fabricated, and tested under one roof. We offer full OEM and ODM customization, flexible MOQ, short lead times, and a damage-free delivery guarantee that protects your investment. If you need a system window that performs as specified and arrives on schedule, Contact Our Team to discuss your next project.
A Complete Product Portfolio from One System Windows Manufacturer
Our Core – Aluminum Alloy System Windows
Our core offering as a system windows manufacturer centers on aluminum alloy windows that are engineered for thermal performance, structural rigidity, and design flexibility. We produce thermally broken system windows, casement windows, tilt-and-turn units, sliding windows, and curtain wall systems. Every profile is designed by our in-house engineering team and fabricated in our own aluminum processing workshop. Asset integrated: Our aluminum workshop houses CNC cutting centers and multi-axis machining stations that hold tolerances under 0.5 mm, ensuring every sash and frame interlocks precisely for airtight weather performance.
Customization is standard here. You can specify any RAL color, choose from double or triple glazing with low-E coatings, select hardware brands from trusted European suppliers, and adjust dimensions to match your rough openings. We also support custom extrusion profiles for large-scale projects — just provide your CAD file or a sketch, and we will produce a quotation and engineering drawing within one working day. This is the flexibility that a professional system windows manufacturer must offer, and we deliver it consistently.
Complementary Solid Wood Doors & Frames
Global contractors and villa developers often need coordinated window and door solutions for a unified architectural language. That is why we also manufacture solid wood entry doors, interior wooden doors, timber door frames, and matching hardware accessories. Why this matters to window buyers: When you source both windows and doors from the same factory — Jusen — you eliminate the coordination headaches of managing separate suppliers. You get consistent finish quality, synchronized production schedules, and simplified logistics. Our team can deliver a fully matched set of aluminum system windows and solid wood entry doors for your project, all backed by our single-point quality guarantee.
Q: What types of system windows do you manufacture?
We produce thermally broken aluminum windows, casement, tilt-and-turn, sliding, and fixed lite units. All are fully customizable in size, finish, glazing, and hardware. Our design team works with you to select the right profile configuration for your climate zone and aesthetic requirements.
Factory Scale & Production Capacity – What a System Windows Manufacturer Must Deliver
Volume commitments and production reliability are deal-breakers in B2B procurement. Our factory infrastructure is built to handle both small custom runs and large-scale project supply with equal discipline.
Self-Built Workshops & Skilled Workforce
We operate a campus of self-owned workshops covering wood drying, spraying, aluminum processing, and final assembly. Our workforce includes over 200 skilled technicians, machine operators, and quality inspectors, many with more than a decade of experience in joinery and aluminum fabrication. Asset integrated: Our self-built facilities give us total control over every production variable. When we promise a certain finish quality or a specific thermal performance, we are not relying on a subcontractor — we are standing behind work that our own team performed on our own equipment.
Annual Output & Flexible MOQ
Our annual production capacity exceeds 150,000 units of windows and 80,000 units of doors. We achieve this scale through two shifts of production and a lean inventory system. At the same time, we maintain a flexible MOQ policy: we accept orders starting from a single piece for custom sample approval, and we offer volume pricing for full-container project orders. Asset integrated: Whether you need one custom-profile window for a boutique hotel suite or 2,000 units for a villa development, our production scheduling system accommodates both without compromising delivery dates. Bulk orders receive priority lane scheduling and dedicated project management support.
Q: Can you handle small custom orders for system windows?
Yes. Our MOQ is flexible — we accept orders starting from one piece for custom sizes and designs. This allows architects and designers to test samples before committing to larger project quantities.
Advanced Equipment for Precision System Window Manufacturing
Quality starts with the machine tool. We have invested continuously in equipment that enables repeatable precision and surface finish excellence.
Wood Drying & Spraying Technology
Our wood drying workshop uses computer-controlled kilns that bring solid wood moisture content below 8%, a crucial step for preventing warping, cracking, or dimensional change after installation — especially important when wooden door frames are paired with aluminum windows in the same opening. Our spraying workshop is a dust-free, temperature- and humidity-controlled environment with automated UV coating lines. Asset integrated: This controlled environment allows us to apply multi-layer finishes that resist UV fading and moisture penetration. We offer an after-sales guarantee that covers coating integrity; if a defect appears within the warranty period, we replace the unit free of charge — including freight and duties.
Aluminum Processing & Assembly Line
Our aluminum line features CNC cutting centers, multi-axis machining centers, automatic corner crimping presses, and thermal break assembly stations. Every profile is cut, milled, and assembled to tolerances under 0.5 mm, a standard that ensures consistent weatherproof performance across every window in the order. Asset integrated: Our team regularly runs air and water infiltration tests on sample units from each production batch. We maintain a log of all quality check results and can provide a test report for your records upon request.
Q: How do you ensure window quality before shipping?
We conduct a three-stage QC process: raw material inspection → in-process random sampling during fabrication → final performance testing on finished units. Tests include water tightness, air permeability, and wind load resistance per international standards. A full inspection report is provided with each order.
Quality Control System – The Backbone of a Reliable System Windows Manufacturer
A system windows manufacturer is only as good as its ability to deliver defect-free products consistently. Our quality system is structured around three layers of inspection, backed by a damage-free delivery guarantee that takes the risk out of international procurement.
Incoming, In-Process & Final Inspection
Stage one: every incoming batch of aluminum profiles, glass panes, seals, and hardware is checked against specification. Stage two: during production, our QC team performs random dimensional checks and visual inspections at defined intervals. Stage three: finished windows are tested for water penetration, air leakage, and structural integrity using calibrated test rigs. Asset integrated: We archive all test records by batch number. If you need a copy of the test report for your project documentation, we can provide it within 24 hours of request.
Damage-Free Delivery Guarantee
Export shipping is a known risk point for glass and aluminum products. We mitigate this with professional-grade packaging: each window is wrapped in protective film, fitted with corner protectors, and packed in a custom-designed wooden crate that prevents movement during transit. Our guarantee: If any item arrives damaged, we send a replacement free of charge — this is a written commitment in our sales terms. No disputes, no partial credits, no charge-backs. You order with confidence knowing that your supply chain is protected.
Q: Do you offer private labeling for system windows?
Absolutely. We manufacture under your brand name, including custom packaging, labels, and documentation. This is a standard service for our retail dealer and distributor partners.
Core Customers – Who Trusts Us as Their System Windows Manufacturer
The relationships we maintain with different customer types reflect our versatility as a system windows manufacturer.
Global Contractors & Interior Designers
Large-scale villa, residential, and hospitality projects demand windows that meet specific architectural and energy performance criteria. Our engineering team works directly with architects to interpret design intent and translate it into manufacturable profiles. Asset integrated: We provide customized construction drawings and formal quotations within 24 hours — a service that project managers and designers rely on when working under tight bid deadlines.
Retail Dealers & Villa Real Estate Developers
Dealers need reliable supply chains with consistent quality and private branding options. Developers need bulk supply with predictable lead times and on-site delivery coordination. Our North America overseas warehouses support both segments by inventorying popular configurations and reducing transit times for repeat orders. Asset integrated: Our overseas warehouse program allows dealers to hold less stock while still offering short delivery windows to their end customers. For developers, we can schedule phased deliveries that match your construction timeline, reducing on-site storage requirements.
Q: What is the typical lead time for system window orders?
Standard lead time is 15–25 working days, depending on configuration and volume. Urgent orders can be expedited — contact our team for current scheduling availability.
Certifications & Industry Experience – Proof of a Professional System Windows Manufacturer
Credentials matter when selecting a long-term manufacturing partner. Our certifications and track record provide third-party validation of our capabilities.
Quality Certifications
We operate under a quality management system certified to ISO 9001, and our products carry CE marking for European market compliance. We also maintain FSC chain-of-custody certification for our solid wood products, ensuring that timber is sourced from responsibly managed forests. Asset integrated: We undergo annual surveillance audits to maintain these certifications. You can always request the latest certificates and audit reports from our compliance team.
20 Years of Solid Wood & Aluminum Expertise
Since our founding, we have continuously invested in research and development, equipment upgrades, and process refinement. Our team has mastered both traditional mortise-and-tenon joinery for solid wood doors and modern aluminum thermal break technology for high-performance windows. Asset integrated: This dual expertise means we understand how materials behave across different climate conditions — which is directly relevant when specifying windows and doors for projects in varying geographies.
Q: Do you have overseas warehouses for faster delivery?
Yes. We operate overseas warehouses in North America that enable faster shipping and reduced freight costs for repeat orders. This is especially valuable for dealer partners who require just-in-time inventory replenishment.
