The Siam Cement Public Company Limited — universally known as SCG — is Thailand's oldest and largest industrial conglomerate, founded in December 1913 by royal decree of King Rama VI (Vajiravudh) to establish the country's first cement plant and reduce reliance on imported construction materials. Over more than a century of operations, SCG has grown from a single cement producer into one of ASEAN's most diversified industrial groups, with core businesses spanning cement and building materials, petrochemicals, and packaging.
Headquartered at 1 Siam Cement Road, Bang Sue, Bangkok, SCG operates as a holding company with a portfolio of listed and unlisted subsidiaries serving both industrial and consumer markets across Thailand, Vietnam, Indonesia, and broader Southeast Asia. The group generates the majority of its revenues from Thailand, while its regional footprint has expanded significantly through investments in Vietnam and Indonesia.
SCG is publicly listed on the Stock Exchange of Thailand (SET) under the ticker SCC, where it is a constituent of the SET50 and SETHD indices, reflecting its status as one of Thailand's most significant and liquid blue-chip equities. The company's largest single shareholder is King Vajiralongkorn, who holds approximately 30% of shares through the Crown Property Bureau, underpinning SCG's deep institutional ties to the Thai state.
