Changsha Wincraft Aluminum Window Tech Co., Ltd. designs and manufactures aluminum door and window systems for importers, distributors, contractors and architects worldwide. From the first sketch to shop drawings, production, quality inspection and export delivery, one engineering team owns your order — so specifications stay consistent from approval to installation.
No middlemen between your drawings and our production line.
Design proposals and renderings delivered within one working day.
Standard customized orders, with batch scheduling for large projects.
Export packing, customs documents and door-to-door delivery.
Every series is produced to order — profile color, glass build-up, hardware and dimensions are configured around your climate, building code and budget rather than a fixed catalog.
High-performance entrance, patio and interior doors with strong thermal insulation, sound reduction and weather resistance.
Energy-efficient window systems engineered for airtightness, water resistance and long-term operation in demanding climates.
Year-round glass rooms combining corrosion-resistant aluminum frames with multi-layer insulated glass for villas and resorts.
Low-maintenance garden pavilions and pergola structures for residential gardens, hotels and commercial terraces.
We handle personalized design, precise shop drawings, material selection, mass production and reliable delivery under one roof. Whether you need a private-label range for wholesale or a single high-specification villa package, our OEM & ODM workflow keeps quality stable and communication direct.
Share drawings, sizes, climate and code requirements.
Renderings and system recommendation within 24 hours.
Detailed shop drawings and specifications for sign-off.
Cutting, machining, assembly and glazing — about 4 weeks.
Dimensional, finish, hardware and sealing checks before packing.
Export documents, tracking and installation guidance.
Most performance problems we see on overseas projects come from a mismatch between the system and the local climate — not from the aluminum itself. Use this reference from our engineering team as a starting point for your specification.
| Project Condition | Recommended System | Glazing | Finish & Hardware Focus |
|---|---|---|---|
| Cold / heating-dominated climates | Thermal-break casement windows and swing doors with multi-chamber profiles and continuous EPDM gaskets | Double or triple insulated glass, Low-E coating, argon fill, warm-edge spacers | Multi-point locking to compress seals and improve airtightness |
| Hot / cooling-dominated climates | Sliding windows and sliding doors with efficient drainage and solar-shading compatibility | Solar-control Low-E insulated glass; tinted or reflective options | UV-stable seals, high-durability powder coating |
| Coastal / salt-spray sites | Any series with enhanced corrosion protection; sunrooms and pavilions with sealed joints | Tempered or laminated insulated glass | Pre-treated powder coating or anodizing; stainless-steel fasteners and hardware |
| High-wind or storm-prone regions | Reinforced profiles, casement or fixed units sized to design wind pressure | Laminated tempered glass | Multi-point locks, upgraded anchoring and installation details |
| Large openings / indoor-outdoor living | Lift-and-slide or folding doors, slim-frame sliding systems | Large-format tempered or laminated insulated glass | Heavy-duty rollers, low or flush thresholds, smooth multi-panel operation |
Final configurations must always be verified against your local building code, energy regulations and the project's structural requirements. Our engineers review your drawings and confirm profile, glass and hardware selections before production starts.
Selected project renderings from our overseas portfolio. Each project starts with the client's architectural drawings and ends with a fully documented, site-ready shipment.
Changsha Wincraft Aluminum Window Tech Co., Ltd. is an integrated building-materials manufacturer and exporter combining design, production, sales and service.

Multi-scenario solutions for global clients and partners — each buyer type gets a dedicated workflow, not a generic sales script.
Dedicated account support, free product training and professional market guidance, backed by stable supply for long-term, mutually profitable cooperation.
Direct communication with our engineering team, design proposals and renderings within 24 hours, plus a library of completed cases for reference.
Responsive 24/7 online service and an approximately 4-week lead time, with full logistics support from customs clearance to door-to-door delivery.
Practical updates on products, logistics and manufacturing that help buyers plan better projects.
Our customized aluminum sunrooms and garden pavilions now serve high-end villa projects across Europe, Southeast Asia and the Middle East. Corrosion-resistant frames and multi-layer insulated glass adapt to heat, heavy rain and coastal salt spray, while our engineers deliver renderings and construction drawings within 24 hours.
Our full logistics service for cross-border e-commerce sellers and single-household buyers covers customs declaration, complete documentation, real-time cargo tracking and door-to-door delivery — removing the uncertainty small overseas buyers often face with shipping.
We keep investing in intelligent equipment and full-process quality management. R&D, production and finished-product testing follow unified standards, and modular assembly for sunrooms and pavilions reduces installation difficulty on site.
Straight answers on customization, lead times, drawings and shipping. For technical questions about a specific project, our engineers respond directly.
Send your drawings or requirements to [email protected] — an engineer, not a call center, will review them.
