The investigation follows a complaint from Megasteel  Sdn. Bhd., the flat products arm of The Lion Group conglomerate. In the petition, the company contends that imports of foreign-made coils increased between 2012 and 2014, harming domestic producers.

Megasteel makes hot strip from hot briquetted iron, pig iron and scrap melted in a 160-ton electric arc furnace. It has a hot rolled coil capacity of 3.2 million metric tons per year.
