For more than thirty years the Macsteel Group has been trading steel around the globe. From small beginnings in the Far East during the early 1980s, following the acquisition of trading house Leo Raphaely & Sons, steel products are now traded through four regional hubs located strategically in New York, Hong Kong and Dubai.

Over the past 20 years MUR Shipping has been developed as a standalone business, transporting dry cargo around the world. MUR own and operate primarily handysize and handymax dry bulk cargo ships with regular sailings on numerous trade routes. Its major offices are found in Dubai, Johannesburg, Sydney and Copenhagen.

Macsteel International Holdings B.V. was set up as a joint venture between Macsteel Holdings Luxembourg S.à.r.l. (previously Macsteel Holdings Proprietary Limited) and ArcelorMittal South Africa Limited (previously Iscor Limited) around Macsteel’s pre-existing international steel marketing organisation and is headquartered in Amsterdam, a centuries old trading capital. The joint venture started its operations on 1 January 1997.

In the early years a significant part of the steel traded internationally was sourced from Iscor, renamed Arcelor Mittal South Africa (AMSA). Although steel products are today sourced from around the world but AMSA remains an important source of steel products to the Group. Through the joint venture and Macsteel International Trading operations it provides experienced worldwide marketing services and complete supply chain management expertise.

Steel is a commodity that leads economic cycles and the Group reacts swiftly to changing circumstances, allowing it to survive difficult times such as the Asian Crisis of 1997 and the global financial meltdown of 2008, whilst still being able to prosper when demand is strong.
