ASI certifies Guangdong Zhongya Aluminum Co., Ltd. against Performance Standard V3.1

13 January 2026

Guangdong Zhongya Aluminum Co., Ltd. has achieved ASI Performance Standard V3.1 (2023) for the manufacture of aluminium alloy building profiles and general industrial extruded profiles, as well as related activities involved in the production process of doors and windows, and curtain wall components at their facility in Guangdong Province, China.

Aluminium Stewardship Initiative (ASI) today announced that Guangdong Zhongya Aluminum Co., Ltd. has been certified against the ASI Performance Standard V3.1 (2023). The company has an annual production capacity exceeding 200,000 tonnes with production processes including melting and casting, extrusion, anodic oxidation colouring, electro-polishing, electrophoretic painting, fluorocarbon spraying, powder coating, thermal insulation, and deep and fine processing. Its operations produce a range of architectural, curtain wall, industrial, and specialised aluminium profiles, supported by product development, mould manufacturing, and testing facilities.

The ASI Certification program was developed through an extensive multi-stakeholder consultation process and is the only comprehensive voluntary sustainability standard initiative for the aluminium value chain. The ASI Performance Standard V3 and ASI CoC Standard V2 were launched in May 2022 following a multi-year revision process. The ASI Performance Standard V3 defines 11 principles and 62 criteria under three sustainability pillars – Environment, Social, and Governance – with the aim to address pressing sustainability issues in the aluminium value chain, such as biodiversity, Indigenous Peoples rights, circularity, and greenhouse gas emissions. The 2022 Standards and related documents underwent a minor update in 2023, accounting for editorial changes, correction of minor errors and for general clarification, culminating in the release of Performance Standard V3.1 (2023) and Chain of Custody Standard V2.1 (2023).

The independent, third-party audit of Guangdong Zhongya Aluminum Co., Ltd. was carried out by China Quality Mark Certification Group. A full listing of audit findings is available in the summary audit reports, linked below. Three minor non-conformances were identified during the audit under the Criteria 1.1 Legal Compliance, 6.1a-f Emissions to Air and 6.5a-c Waste Management and Reporting. Guangdong Zhongya Aluminum Co., Ltd. will be implementing corrective actions, to be verified in a follow-up audit.
