Godrej launches refrigerators with 10-year warranty against rusting
By Our Corporate Bureau | 20 Apr 2006
The new range of refrigerators is now made with 100 per cent galvanised steel in contrast to regular cold rolled steel. During the galvanisation process, the steel is coated with zinc, which renders the surface resistant to corrosion. When atmospheric oxygen comes in contact with zinc, the formation of Zinc Oxide helps prevent the breakdown of the surface integrity of the base steel substrate, unlike the iron oxide (rust) in regular steel.
The refrigerators are further coated with epoxy powder. This dual process of galvanisation and powder coating gives each refrigerator a double protection.
According to metallurgist Dr NC Jain, , "A zinc coating has the unique property of preventing oxidation of the protected surface by forming a barrier and thus acting as a sacrificial anode. This process of galvanisation is widely used in making cars and ships rust resistant."
From April 2006, all refrigerators being manufactured by Godrej are made using ZOP technology and will carry the 10-year 'rust-free' warranty.
The Godrej Group is one of the largest manufacturers of home appliances in India and in 1958, it became the first Indian company to manufacture refrigerators in the domestic market
