The Ramaraju Surgical Cotton Mills was founded in 1939 in Rajapalayam, Tamil Nadu, to take advantage of the availability of the cotton grown by local farmers. The company, along with Rajapalayam Mills Ltd. that was established in 1935, were instrumental in transforming the region from an agrarian to an industrial society.
The Ramaraju Surgical Cotton Mills is the largest producer of absorbent cotton, gauze, bandages and other wound-care products in Southern India with a production capacity over 125 tons of medical grade bleached cotton and over 1.5 million square meters of bandages and gauze products. Over the years they have diversified into spinning and weaving, producing some of the world’s finest cotton yarn and manufacturing premium fabrics for shirting, bed linens and Jacquard cloth. The Ramaraju Surgical Cotton Mills is well known for quality products that meet customer expectations, which has helped them build a loyal base of satisfied customers spread across the globe.
The climate of Rajapalayam is semi-arid and the temperature range is 20 °C to 37 °C. It has a high mean temperature. The mill requires humid temperature controlled environment to process cotton yarns and fabrics. Moreover, washing, de-sizing, bleaching, rinsing, dyeing, printing, coating and finishing involves various chemical processes. Metal roof have little or no resistance to chemicals and processes employed in the mill. They start corroding rapidly exposing and risking the sophisticated machinery, processes, personnel and materials to the elements and structural failure.
The plant needed roofing sheets that will be durable, last long and provide a comfortable working condition for the employees.
Ramco Greencor – Non-asbestos Fibre Roofing Sheets
Made of high quality non-asbestos fibre & cement, Ramco Greencor is the new age roofing sheet. Unlike metal roofing sheets, it is not affected by pollution or marine environments. It stays strong and provides a perfect working condition for years.
|Sl.No||Properties||GI Metal Sheets||Greencor Sheet||Inference|
