"This is a positive development for Steel & Tube providing greater liquidity in the trading of Steel & Tube shares," Taylor said.
In late 2008 Arrium made a tilt to buy the remaining stake in Steel & Tube, offering $4 a share, but later gave up when it became clear world markets were set to plunge.
This month, Arrium rejected a A$1 billion t bid by an Asian consortium Steelmakers Australia last week, that was led by Hong Kong commodities trader Noble Group and South Korean steel firm POSCO.
Arrium's Steve Hamer has resigned from the Steel & Tube board, effective immediately. Arrium-appointed Dean Pritchard will stay on the board and relinquish the chair to John Anderson.
In August, Steel & Tube reported a 23 per cent fall in annual profit to $13.1 million as dwindling demand and stiff competition squeezed margins. Sales rose 5 per cent to $405.4 million.
ASX listed Arrium shares last trade at 78.7 Australian cents and have gained 17 per cent so far this year.
