The Siam Cement Public Company Limited

The Siam Cement Public Company Limited, commonly known as SCG, is Southeast Asia's oldest and largest cement and building materials conglomerate, established by royal decree of King Rama VI in 1913. Headquartered in Bangkok, Thailand, the company has grown into a regional powerhouse with fiscal year 2025 global sales exceeding $15.1 billion USD, serving as an indispensable market benchmark on the Stock Exchange of Thailand and a indicator for ASEAN economic health.

Core Business

SCG's foundational strength lies in cement and construction materials, where it manufactures and distributes a comprehensive range of products including cement, mortar, roofing tiles, concrete, and wall materials. These products have established SCG as the undisputed market leader across Southeast Asia, with the company's green building materials market share ranking first in the ASEAN region. Beyond construction, SCG operates a significant chemicals division focused on petrochemical products, and a packaging segment encompassing both paper and plastic packaging solutions, with the packaging subsidiary SCGP operating over 56 manufacturing facilities across the region.

Global Presence

SCG maintains operational and commercial networks across over 50 countries and regions worldwide, with primary market concentration in the ASEAN bloc—particularly Thailand, Vietnam, Indonesia, and the Philippines. The company employs approximately 55,000 to 55,578 workers globally and operates hundreds of production facilities, including dozens of large-scale cement and building materials plants throughout Thailand and Southeast Asia. Notably, SCG's international expansion includes the $5 billion Long Son Petrochemical Complex (LSP) in Vietnam, manufacturing bases in the United Kingdom and United States, and a planned joint venture for hard packaging production in America to navigate trade policy challenges.

Key Strengths

SCG differentiates itself through a powerful combination of century-old brand heritage, dominant market position in ASEAN construction materials, and aggressive technology-driven efficiency gains—having achieved cost savings exceeding 4.3 billion baht through AI and robotics deployment. The company's commitment to sustainability, including a $6 billion investment in decarbonization from 2025 to 2030 and development of the world's largest industrial thermal battery facility, positions it at the forefront of green industrial transformation in Southeast Asia.
