As demand for glutinous rice had grown to other parts of the country, in 1970, Srithaimai Rice Mill decided to expand its core business by investing in three different business types; Transportation, Construction and Petrol businesses mainly to transport rice and construction materials. These investment decisions had been a major accomplishment in Srithaimai history; the businesses were amazingly and logistically supporting each other.

Rice production, construction, transportation, and petrol business have become Srithaimai’s core businesses since then and became known as SRITHAIMAI GROUP.
