Trusted Nickel Strip Manufacturer Since 1974
Ramani Steel House has manufactured nickel strip in Mumbai since 1974. Over 52 years the work has narrowed to what it is now known for: pure nickel strip, H type nickel strip and nickel busbar for lithium-ion battery packs, supplied to pack builders, EV manufacturers and energy storage integrators across India and in 17+ export markets.
Strip is slit, cut and finished at our own works at 65/73, C.P. Tank Road, Mumbai, Maharashtra 400004, India rather than bought in and resold, which is what makes custom pitch, width and hole patterns a normal order rather than a special case.
