Recognizing the substantial demand for fibre cement sheets in Sri Lanka, Ramco Industries started a wholly-owned subsidiary company - Sri Ramco Lanka (Private) Limited in 1999. The first factory was set up at Makandura Industrial Park in North West Province.

The company has been accredited with ISO Quality Systems Certificate (ISO 14001/EN ISO 14001) by RWTUV Systems GmbH, Germany, to the effect that it has established and applies an Environmental Management System for manufacture and supply of fibre cement corrugated sheets, flat sheets and accessories.

A new plant was inagurated at Matugama in Kalutara District. Currently the company has three modern plants to manufacture fibre cements corrugated sheets for roofings and flat sheet for ceiling and partition purposes with a combined production capacity of 2,60,000 metric tonnes per annum.
