ZMARTBUILD is promoted by SCG , a leading manufacturing conglomerate in Thailand and South Asia. SCG was established in 1913 following a royal decree of His Majesty King Rama VI to produce cement, the main building material for infrastructure projects that greatly contributed to the progress of the country during that period. Since its founding, we have grown continually and diversified into three core businesses, namely SCG Cement-Building Materials, SCG Chemicals and SCG Packaging.
