Trialliance Signs Rayong Land Deal for Planned Automotive Hose Production Base
WHA announced on 22 May 2026 that it had signed a land purchase agreement with Trialliance Technology (Thailand) at WHA Industrial Estate Rayong. The company plans to establish a facility for automotive and industrial rubber hoses; the confirmed stage is land acquisition, not groundbreaking or production start.
Trialliance specialises in automotive and industrial rubber hoses, including turbocharger hoses. The planned base is intended to manufacture automotive hoses and related essential components for domestic and international demand and to serve as an important production node in the company's Southeast Asian expansion.
The Rayong location places the project close to Thailand's automotive cluster and component network. The official announcement does not state the land area, investment amount, construction schedule, expected capacity or employment number, so none of those figures should be inferred.
