NSL Ltd was incorporated in 1961 as The National Iron and Steel Mills to support Singapore's nation-building efforts in infrastructural and residential development.

On the back of this national role, the Group began to diversify into related areas in the 1980s to broaden its earnings base. It began by expanding into steel fabrication and construction-related products and services. In the early 1990s, in tandem with product diversification, the Group regionalised and expanded into Electronic businesses. It also changed its name to NatSteel Ltd.

In the new millennium, the Group maximizes value for shareholders through unlocking the value of its businesses. The Group sold its electronics businesses (ie. NatSteel Electronics and NatSteel Broadway) in 2000s. In line with the group's objective of enhancing its shareholders value, the group sold its steel businesses in 2004.

With the exit of its steel business, the company assumed its present name of NSL Ltd with effect from 16 October 2008.

The new logo is an inspiration from Chinese knot. It is an expression of an auspicious icon symbolizing wealth, friendship, health and happiness. It is also a graphic representation of a strong partnership formed between NSL Ltd and its employees, customers or associates. Vividly expressed in modern corporate blue and metallic silver, this symbol reflects an established yet modern and progressive organization.
