Slim Frame Aluminum Windows – Premium Quality, Custom Manufacturing & Reliable Global Supply
At Jusen Doors & Windows Manufacturing Co., Ltd., we have spent 20 years perfecting the art of aluminum window production. Our slim frame aluminum windows are engineered for contractors, interior designers, retail dealers, and villa developers who demand narrow sightlines without compromising thermal performance or structural integrity. With our self-built aluminum processing workshop, independent design team, and North America overseas warehouses, we offer a one-stop OEM & ODM solution that ensures stable supply and consistent quality for every project. Whether you need a small batch for a custom home or bulk delivery for a commercial development, our factory is ready to deliver.
Our Slim Frame Aluminum Window Products – Engineered for Performance and Design
Our product range covers the most demanded slim frame configurations in the global market. Every profile is manufactured in our own aluminum processing workshop, where we control extrusion precision, surface treatment, and assembly tolerances. Our engineering support team works directly with clients to adapt our standard designs to local building codes and project-specific requirements.
Slim Casement Windows – Thermal Break Profiles and Sealed Glazing
Our slim casement windows use thermal break aluminum profiles that reduce heat transfer while maintaining a frame width as narrow as 20 mm on the visible face. We offer double and triple glazing options with argon gas fills and warm-edge spacers. Because we operate our own spraying workshop, we can apply any RAL color or anodized finish with consistent coating thickness. Every casement undergoes air and water tightness testing before shipment, ensuring performance that meets international standards.
Sliding and Lift-and-Slide Slim Frame Systems
For projects that require large openings and unobstructed views, our sliding and lift-and-slide slim frame systems deliver smooth operation with frames as slim as 25 mm. Our independent design team can modify the profile design to accommodate local wind load requirements or hardware preferences. We use multi-point locking systems and stainless steel rollers to ensure durability even in heavy-use commercial settings. The slim sightlines maximize glass area, making these windows a popular choice for modern villas and high-end apartments.
Fixed and Tilt-and-Turn Options for Architectural Flexibility
Our fixed slim frame windows are designed for maximum glass exposure, with frames that disappear into the facade. Tilt-and-turn variants provide both inward tilting for ventilation and full inward opening for cleaning. Through our ODM service, we can customize handle styles, hinge finishes, and glazing thickness to match your design vision. We also offer wood grain finishes applied in our spraying workshop, combining the slim aluminum profile with a warm timber aesthetic.
Supply Chain Strength – Why Contractors and Developers Choose Our Factory
Our supply chain is built on vertical integration. We do not outsource critical production steps, which means we control quality, lead time, and cost from raw material to finished window. This is why global project partners trust us for repeat orders.
Integrated Production from Raw Material to Finished Product
We operate our own wood drying, spraying, and aluminum processing workshops on a single campus. For slim frame aluminum windows, this means we handle extrusion quality checks, CNC cutting, corner crimping, glazing, and hardware installation in-house. By eliminating third-party processing, we reduce the risk of dimensional errors and finish inconsistencies. Every batch of aluminum profiles is inspected for wall thickness tolerance and surface uniformity before entering production.
Consistent Quality Through In-House Testing
Our quality control team performs air permeability, water tightness, and structural strength tests on random samples from each production run. With 20 years of aluminum window experience, we have developed standardized inspection protocols that catch defects before shipment. We also test thermal performance using calibrated hot-box methods for projects that require certified U-values. This commitment to testing means that every slim frame window leaving our factory meets the specifications we agreed upon.
Stable Supply Capacity and Flexible MOQ
We understand that B2B partners need reliability. Our production lines can handle orders ranging from 50 units to several thousand, and we maintain flexible minimum order quantities to support retail dealers who are building a new product line. For larger projects, we schedule production in phases to match your construction timeline. Our North America overseas warehouses allow us to hold buffer stock, reducing lead times for urgent restocking.
OEM & ODM Cooperation – We Build Your Slim Frame Window Under Your Brand
Our OEM and ODM services are designed to help you grow your business without investing in your own factory. We become your manufacturing partner, handling everything from profile sourcing to final packaging.
Full OEM Service – Your Specifications, Our Manufacturing Precision
When you choose OEM, you provide the drawings, profiles, or performance targets, and we manufacture accordingly. Our team reviews every dimension, hardware specification, and finish requirement before production begins. We maintain your approved sample on file and match it for every subsequent order. For contractors who need windows that match existing building openings, we offer custom sizing with no additional tooling fees for repeat orders.
ODM Development – From Concept to Production-Ready Slim Frame Windows
Our independent design team can develop new slim frame models based on your market needs. Perhaps you want a narrower sightline than what is currently available, or a specific locking mechanism for a regional security standard. We handle profile design, thermal modeling, prototype fabrication, and testing. Once approved, we produce your custom windows with your branding and packaging. This service is especially popular with retail dealers who want an exclusive product line.
Private Label and Distributor Programs
For dealers who want to sell slim frame aluminum windows under their own brand name, we offer private label programs. We apply your logo to frames, packaging, and documentation. We also provide marketing support materials such as product specification sheets and installation guides. Our MOQ for private label is flexible, and we can start with a small trial order to validate the market before scaling up.
Competitive Pricing – How We Deliver Value Without Sacrificing Quality
Our pricing structure reflects our manufacturing efficiency. Because we own the production chain, we avoid the markups that come with subcontracting.
Cost Advantages from Vertical Manufacturing
When you order slim frame aluminum windows from Jusen, you are paying for raw materials, processing, and assembly — no middleman margins. Our self-built workshops reduce per-unit costs by approximately 15–20% compared to manufacturers who outsource extrusion, surface treatment, or glazing. We pass these savings to our B2B partners, especially on bulk orders.
Transparent Quoting with No Hidden Costs
We provide formal quotations within 24 hours of receiving your project details. Every quote includes a breakdown of material costs, tooling (if applicable), packaging, and shipping options. We also include custom construction drawings at no extra charge for OEM and ODM orders. There are no surprise fees for design changes or sample production. For long-term partners, we offer tiered pricing based on annual volume.
Global Logistics Network – Delivering Slim Frame Windows to Your Site
Logistics is a core part of our service. We have built a distribution network that ensures your slim frame windows arrive on time and in perfect condition.
North America Overseas Warehouses for Faster Delivery
We maintain warehousing in North America to serve contractors and dealers in the US and Canada. This reduces ocean transit times and allows us to ship partial orders from local stock. For partners who need just-in-time delivery, we can stage containers at our overseas warehouses and release them according to your construction schedule.
Damage-Free Packaging and Shipping Guarantee
Slim frame windows require careful handling. We use foam corner protectors, edge guards, and shrink wrap for each unit, followed by plywood crating for container loading. Our packaging team has developed specific protocols for aluminum windows with narrow frames, which are more prone to twisting if not properly supported. We back this effort with a full shipping damage after-sales guarantee — if a window arrives damaged, we replace it quickly.
Customs and Documentation Support for International Orders
We handle all export documentation, including certificates of origin, packing lists, and commercial invoices. Our logistics team coordinates with freight forwarders to ensure smooth customs clearance in your country. For first-time importers, we provide guidance on duties and taxes so there are no surprises at the border.
After-Sales Support – We Stand Behind Every Slim Frame Window
Our relationship does not end at shipment. We provide comprehensive after-sales support to ensure your project succeeds.
Full Shipping Damage After-Sales Guarantee
If any slim frame window is damaged during transit, we will replace or repair it at our cost. Our team reviews photographic evidence within 48 hours and ships replacement parts or units by air if necessary. This guarantee covers all international orders, giving our partners peace of mind when importing from overseas.
Technical Support and Custom Construction Drawings
Within 24 hours of your inquiry, we provide installation drawings, shop drawings, and technical guidance tailored to your project. Our engineering team is available by email and video call to help contractors and installers with tricky installations. For large-scale projects, we can provide on-site training or remote support during the installation phase.
Long-Term Partnership and Reorder Support
We treat every dealer, contractor, and developer as a long-term partner. Repeat clients receive priority production scheduling, consistent pricing, and proactive communication about lead times. If you need to increase order volume mid-project, we adjust our production plan to accommodate. Our goal is to make your supply chain as reliable as possible.
Case Studies – How We’ve Supplied Slim Frame Aluminum Windows to Global Projects
Our experience spans residential, commercial, and retail projects across multiple continents. These examples show how we partner with clients to deliver results.
Villa Development Project – Custom Slim Casement Windows
A villa developer in the Middle East needed 1,200 custom-colored slim casement windows with thermal break profiles for a luxury residential complex. Our design team matched the client’s RAL sample and produced certified test reports for local building approval. We delivered in three phases over six months, with zero damage reported. The client has since placed two repeat orders for subsequent phases.
Retail Dealer Partnership – Private Label Slim Frame Window Line
A North American retail dealer wanted to launch an exclusive slim frame window series under their own brand. We developed three ODM models with different sightline widths and hardware options. Our team created branded packaging, installation manuals, and marketing sheets. Starting with a 50-unit trial, the dealer scaled to full container orders within one year.
Commercial Complex – High-Performance Fixed Slim Windows
For a commercial office complex in Southeast Asia, we supplied 800 fixed slim frame windows with low-E glazing and structural silicone glazing. The frames were designed to withstand typhoon-level wind loads while maintaining a 25 mm sightline. Our engineering team provided shop drawings and installation support remotely. The project was completed on schedule, and the client reported energy savings of 18% compared to their previous building.
Frequently Asked Questions About Slim Frame Aluminum Windows from Our Factory
What thickness aluminum profiles do you use for slim frame windows?
We typically use wall thicknesses between 1.6 mm and 2.0 mm for slim frame profiles, depending on the application and wind load requirements. Because we operate our own aluminum processing workshop, we can adjust the extrusion die design to achieve precise wall thickness tolerances. Our quality team measures every batch with ultrasonic gauges to ensure consistency.
Can you produce slim frame windows in custom colors and finishes?
Yes. Our in-house spraying workshop applies powder coating, anodizing, and wood grain finishes. We can match any RAL color or provide custom samples for approval. For projects that require a consistent finish across multiple building phases, we retain color samples and coating parameters to ensure batch-to-batch consistency. Our independent design team can also help you select finishes that complement your overall architectural scheme.
What is your typical lead time for a bulk slim frame window order?
For a standard OEM order of 200–500 units, lead time is approximately 25–35 days from approval of drawings and sample. More complex ODM projects with new profile tooling may take 45 days. Thanks to our North America overseas warehouses, we can expedite smaller orders from stock for US and Canadian partners. We always provide a confirmed lead time in our formal quotation.
Do you provide installation drawings and technical support?
Absolutely. Within 24 hours of your inquiry, we provide custom construction drawings. Our engineering team can also review your project plans and recommend the best slim frame configurations for your openings.
