Our story
Seaman Industry (Thailand) Co., Ltd. was established on 27 August 1996 as a manufacturer of thermoplastic road marking material under the Sea Man® brand, and has built its reputation as a pioneer of this industry for over three decades.
With a commitment to international standards from the very start, Seaman Industry became the first manufacturer in Thailand to be certified to ISO 9002 for thermoplastic road marking material.
Over more than 30 years, the company has continuously improved its production processes, earning the trust of government agencies — both the Department of Highways and the Department of Rural Roads — as well as private-sector partners nationwide.
Today the company manufactures and supplies thermoplastic, traffic paint, cold plastic, primer and reflective glass beads to customers across Thailand, under the ISO 9001:2015 quality management system.
