Factory Location

Focusing on aluminum alloy doors and windows,
Centered on project order delivery.

We organize production around aluminum alloy profiles, metal frames, thermal insulation strips, glass, hardware, surface treatments, and packaging methods, helping clients transform procurement needs into executable product configurations.

The factory can handle sample prototyping, small-batch trial orders, and large-scale engineering orders, suitable for door and window distributors, construction contractors, developers, and OEM/ODM brand clients.

Before formal communication, clients can first confirm product types, target markets, performance grades, packaging methods, and delivery schedules to reduce repeated modifications during drawing refinement and sampling stages.
