Nigerian Foundries Ltd (NFL) is the leading ferrous foundry group in sub-sahara (excluding South Africa) with a total installed capacity of 8,500 metric tons per year. It has two plants, one in Ilupeju Lagos State and one at Sango-Otta, Ogun State. NFL started as a small grey iron foundry at Ilupeju in 1969 by the Barberopoulos brothers making municipal castings and water pipeline fittings.

In 1990, following an expansion, of plant and machinery, NFL moved into the production of steel iron alloy castings. This was done with a technological transfer agreement with Messrs. Bradley & Foster of the United Kingdom who were specialists in wear and heat resistant alloy castings.
In 1995/96 NFL purchased an old foundry in Otta, Ogun State with a land area of 54 acres. Following another major expansion, in 2002/03 the Otta Plant became a reality adding to its installed capacity of 2,500 tons an additional 6,000 tons of metal capacity.
