About us
Windows Door Factory is an export manufacturer of aluminum, aluminum-clad wood and solid wood windows and doors in Shanghai, China.
Built around export orders
A typical order starts with a window and door schedule from a builder in North America, a distributor in Australia or an architect in Europe, and ends with crated units leaving for their port. In between, our engineers choose the profile series, glass make-up and hardware that meet the project's performance and code targets, issue shop drawings for approval and follow production through inspection and packing.
Our catalog lists 444 models in six families: aluminum windows, aluminum doors, wood & clad-wood windows, wood doors, slim-frame series and smart & motorized systems. Most are made to order, so sizes, finishes, glazing and hardware are configured for each project.
Inside our production
Profile cutting, frame assembly, insulating glass, inspection and export packing — all under one roof.
