东南铝业有限公司

What 东南铝业有限公司 does

东南铝业有限公司 (Southeast Aluminum Co., Ltd.) is a Xiamen-based aluminum extrusion and surface treatment manufacturer founded in 1984. Originally established as the first Sino-foreign joint venture in the Xiamen Special Economic Zone by Hong Kong China Aluminum Company, Xiamen United Development (Group), and China Aviation Technology Import-Export Xiamen Branch, the firm was converted to a wholly foreign-owned enterprise in December 2006 when the foreign investor acquired all Chinese equity. Operations are run from a 20,000 square meter facility in Huli Industrial Park, Xiamen, Fujian Province, producing architectural and industrial aluminum profiles.

The company's core technology is integrated aluminum extrusion manufacturing combined with four surface treatment capabilities: oxidation and coloring, electrophoretic coating, powder coating, and downstream machining into finished door/window, curtain wall, and industrial components. The product portfolio spans architectural profiles (oxidized/electrophoretic/powder-coated profiles, door/window systems in 50-888 series, hidden-frame and visible-frame curtain wall systems), and industrial profiles including photovoltaic solar mounting brackets, aluminum pallets and trays, handrails, electronic enclosures (mobile phone shells), LED and plant-lighting heat sinks, refrigeration profiles, foot pedals, and sports/medical equipment brackets. The catalog comprises more than 10,000 product structures. The company holds ISO9001-2015 certification, AAA Credit Enterprise status, and a Class A qualification for building curtain wall engineering professional contracting obtained in December 2018.

Commercially, the company operates a direct B2B sales model targeting construction, solar energy, electronics, automotive, and industrial customers, with named reference projects including the Xiamen International Convention and Exhibition Center, Xiamen Industrial Bank, Guanjie Technology, San'an Integrated Circuit, Xiamen Public Security Bureau Building, Xiamen University Zhangzhou Campus, Yuanhua International Hotel, and Longyan Yixian. Pricing is quotation-driven with no public disclosure, and export operations reach Japan, the USA, Hong Kong, and Southeast Asia. The company is privately held, with no venture funding, public listing, or institutional investor disclosed in the input data, and no management team is publicly identified.
