The year was 1938. It was a time when the reverberations of the Industrial Revolution had not yet reached the interiors of South India. Despite scarce capital and resources, Mr. P A C Ramasamy Raja setup the first spinning mill at Rajapalayam, which later became the focal point of the Ramco Group. His sharp focus on technology and quality has inspired a generation of entrepreneurs and formed the basis for the collective vision of the Group.

Today, under the stewardship of the current Chairman Mr. P R Ramasubrahmaneya Rajha, the Ramco Group has expanded into a USD 1 billion industrial conglomerate with interests spanning cotton and synthetic yarn, cement, building products, software solutions, wind-energy and more. The Group has become one of the most reputed business houses in India and has achieved international recognition for its quality products and services.

RAMCO INDUSTRIES LIMITED

Ramco Industries Ltd is one of the best performing, highly efficient producers of Fibre Cement Sheets in India and has pioneered and introduced the innovative Calcium Silicate Board, a versatile building material, using Japanese technology from the A & A Corporation, Japan Located at Keshwana (Rajasthan) and Arakonam (Tamil Nadu). Ramco Industries’ two world class manufacturing plants have a combined capacity of approx. 75,000 metric tonnes per annum. Hilux boards are composed of a composite matrix of Portland cement and mineral additives reinforced with special grade cellulose fibres.

Hilux Calcium Silicate boards are fast replacing conventional building materials such as Gypsum boards, Plywood & Plaster of Paris across the international markets by virtue of their sheer versatility. Several landmark and iconic structures that have stood the test of time bear the Hilux stamp of excellence, signifying stronger, safer and aesthetically appealing buildings.
