YHS International

What YHS International does

YHS International Ltd. is a Thailand-based aluminium facade company specializing in the design, fabrication, and supply of aluminium doors, windows, and curtain wall systems for commercial and residential construction projects. Founded in 1991 and headquartered in Huai Khwang, Thailand, the company operates with a workforce of 51-100 employees and historically served the domestic construction sector as a specialist sub-contractor/fabricator in the building envelope value chain. Its primary use case is the delivery of energy-efficient building exteriors and curtain wall assemblies intended to meet sustainable construction and smart building requirements.

The company's commercial model centers on project-based contracts with construction and building clients, with revenue tied to the delivery of customized aluminium facade systems. No public pricing information, product catalog, or revenue figures are disclosed in the source material, and the company does not maintain a mobile application or published software platform. There is no documentation of internal R&D, proprietary technology stack, or digital product offering beyond the physical fabrication business.

In December 2023, YHS International was acquired by Japan-based YKK AP Inc., a major regional building products company, alongside Siam Metal Co., Ltd. The transaction was structured to strengthen YKK AP's global supply chain and to expand its curtain wall business across Asia. Financial terms were not disclosed, and YHS now operates as a subsidiary of YKK AP Inc., aligning its Thailand-based manufacturing footprint with the parent's broader regional strategy.
