With more than ten years in building materials and our own production base, we control aluminum profile testing, surface treatment, and complete window assembly in-house. Every door and window is checked through visible details.
System R&D · Performance Compliance
We do not simply assemble parts. We build integrated systems. Air tightness, water tightness, and wind pressure resistance are verified through structured testing, giving projects a real system window solution.
Stable Capacity · Reliable Delivery
Monthly capacity covers 20,000 m²+ of doors and windows and 5,000 m²+ of sunrooms. Standard orders are usually delivered in 15-20 days, with urgent schedules discussed case by case.

| Comparison Dimension | Regular Trading Supplier | Qinhan System Windows & Doors |
|---|---|---|
| Factory Capability | Tends towards order transfer and inquiries, with production details being uncontrollable. | Owns processing, manufacturing, and sample display, making product structure, craftsmanship, and delivery schedule more controllable. |
| Solution Confirmation | Only quotes based on model number, easily overlooking project conditions. | First, review drawings, dimensions, opening methods, performance targets, and application scenarios. |
| Configuration Support | Profiles, glass, hardware, colors, and packaging confirmed separately. | Profiles, glass, hardware, colors, packaging, and documentation confirmed simultaneously. |
| Delivery Follow-up | Issues are temporarily transferred, making information prone to gaps. | Business, technology, production, and quality control are divided and followed up, making the milestones clearer. |
| Export Support | Packaging, documentation, and after-sales coordination are unstable. | Supports export packaging, documentation synchronization, sample prototyping, and OEM/ODM customization. |
