About Qingdao Jinshi Jianxin Technology Co., Ltd.

Jinshi Aluminum is a Qingdao-based manufacturer for buyers who need dependable extrusion quality, clear communication, and export-ready delivery. Our work covers industrial framing, architectural profile systems, aluminum surface finishing, and value-added CNC machining.

Production and Quality Focus

Profile quality is not only about alloy chemistry. It depends on die control, extrusion temperature, quench and ageing discipline, straightening, surface protection, and checks before packing. We support each order with practical specifications such as alloy and temper, dimensional tolerances, finish requirement, cut length, packaging method, and requested inspection documentation.
