Continuous Cast Copper Wire Rod
Larkindia a market leader special in North India in the production of ETP copper wire ROD. It uses licensed technology SCR 2000 from southwire USA. Continual improvements, manpower trained by southwire personnel and regular meetings at southwire USA for improvements in process efficiency in cost and effectiveness for all men machine and materials. A small part of the ETP ROD is converted in NUGGETS which are used as anode material by the plating industry.
Larkindia boasts of an unmatchable skilled and experienced team.
