Automobile Assembly and EDP Painting

Thai Rung Union Car Plc (‘TRU’) is well known as Thailand’s leading auto body builder, with a long history of innovative auto conversion based on pick-up platforms, culminating in the award-winning TR Adventure Master SUV-type station wagon. Our many years of experience form a durable foundation for our capability, which is further enhanced by the combination of qualified personnel with advance technology, supported by fully integrated assembly facilities incorporating EDP (Electro Deposit Primer) dip process and state-of-the-art paint shop.

With almost forty years of experience in assembly, TRU workmanship is appreciated by our customers, both domestic and international. In each and every assembly process, we combine our qualified personnel with advanced technology equipment to guarantee the first class quality of our vehicles

Products assembled by TRU range from luxury off-road four-wheel-drive sports station wagons, through family station wagons and double-cab pick-up trucks on pick-up truck platforms, to multi-purpose van/minibus designed and built by Thai Rung. Contract assembly work carried out for auto makers has included complete vans, excavator cabs and pick-up cargo boxes.

Apart from providing full assembly facilities and experience, TRU is unique in offering a one-stop service based on its end-to-end engineering capabilities, from product development, design and engineering, tooling, stamping, seats and interiors, through to final assembly (welding, painting and trim).
