ESC has been a registered dealer of M/S Alloy Steel Plant, Durgapur for their Alloy Steel Products since 1990. The forging industries, General Engineering industries and the
Bore well and Mining industries in Eastern and Southern India have been the main consumers of the company’s products. When Button Bits, one of the many end-products bore down 1500 feet below the earth’s surface in drills, exacting quality controls is the byword for the metal used for its manufacture. The ten-fold rise in annual turnover, from
Rs. 20 million to Rs. 200 million over the last decade validates the company’s efficiency and the quality of service provided to its customers.

Steel
Making & Forging at Hyderabad Plant :
In
the future we are planning to setup an Induction Melting
Furnace and a Forging Industry at Hyderabad. 2 Acre
(approx) land has already been acquired for this purpose.
For our Steel Melting Furnace we shall be requiring scrap
for Tool & Alloy Steel Materials.
