National Intergroup will leave the steel business.

According to the firm’s chairman, Howard M. Love, National Intergroup plans to sell the remaining half of its National Steel Corp. subsidiary by the end of the decade. The Pittsburgh-based company sold its Weirton Steel division to its West Virginia employees in 1983, the first in a series of moves that has taken the company away from heavy manufacturing and toward distribution businesses. Love recently told securities analysts that National Intergroup will try to sell its 50% stake in the steel company for at least 80% of its $309-million book value.
