Ramco Greencor - Non-asbestos Fibre Roofing Sheets

About the Customer

Indian Railways transports 8.1 billion people and 1.1 billion tons of goods annually and has 7216 stations across India. Indian Railways can be defined as the lifeline of India considering the important role it plays in day to day life.


Every railway station offers basic amenities for the passengers and ensures that these are safe and clean, thanks to the slew of initiatives taken by the Central Government.

Providing a proper roofing for the passengers across all platforms in every station is one of the prime requirements of the department. Few years ago, majority of railway stations across India switched on to metal roofing sheets replacing the old asbestos sheets. The metal sheets were chosen for its look and on the belief that they may last long.

On the contrary, India has tropical climate prevailing across the major parts of the country – hot summer, cold winters and a heavy monsoon downpour. Also, India is a developing country with a booming economy opening up large manufacturing plants resulting in a polluted environment. India is a peninsula with almost 60% of the states on the coastal belt exposed to marine conditions.

The tropical climate, pollution and marine environment is a potent mix to easily corrode and damage the metal roofing sheets.

Added to this the coastal part is prone to cyclonic storms with strong winds of upto 100 kms/hour. Metal sheets have a low wind velocity resistance with which it cannot resist strong winds and fly off. Apart from resulting in loss of material they may turn into flying swords which can harm the public badly.

Hudud cyclone which affected in 2014 in Vizag and Vardhah cyclone in 2016 at Chennai wreaked havoc and left every station roofless including the iconic Chennai Central Station.

The metal roofing sheets also has poor thermal insulation which resulted in a hot & sultry environment for the passengers resting under them.
