We are an aluminum alloy door and window factory with 20 years of manufacturing experience, located in Shaanxi Province, China. We do not subcontract orders.

Export quality complies with the EN 14351-1 standard, covering thermal break windows, heavy-duty sliding doors, curtain walls, and facade supporting products. We use project drawings, profile samples, glass configurations, hardware solutions, and packaging requirements as the basis for communication, helping clients clarify product direction, performance boundaries, and delivery conditions before inquiry.

From sample procurement, small-batch trial orders to project bulk supply—Qinhan provides stable OEM/ODM customization support for global engineering contractors, distribution channels, and door and window brands.
