Ernest T. Weir didn’t do things by halves.
In 1929, he stitched together three industrial giants: Weirton Steel, Great Lakes Steel, and Hanna Iron Ore. The result was National Steel Corporation. It wasn’t just about rolling steel. Weir owned the mines. He owned the coalfields. He controlled the supply chain from dirt to product.
This vertical integration paid off. While other steelmakers bled money during the Great Depression, National Steel stayed afloat. It was the only steel company to post a profit in 1932. Hard times don’t scare away efficiency.
Weir was a self-made rugged individualist. He hated the New Deal. He fought unions tooth and nail. His weapon? Wage hikes.
When profits rose, he raised pay. Unilaterally. Without a contract. It undercut the appeal of ironworkers and steelworkers unions before they could gain traction at his Weirton plant. Workers liked getting paid more than they liked picket lines. Smart move. Or ruthless. Depends on who you ask.
Fast forward to the 1980s. The landscape changed.
National Intergroup, Inc. (NII) was established in 1983. Its sole purpose? Diversify National Steel. The company moved headquarters from Pittsburgh to Dallas in 1991. National Steel itself relocated to Mishawaka, Indiana, in 1992.
Why move? Money follows opportunity. And opportunity followed new markets.
Diversification and Foreign Partners
Steel is cyclical. It booms and busts. Weir’s successors knew that. They spread the risk.
In 1968, they bought Hastings Aluminum Products. Two years later, they picked up Pittsburgh Aluminum Alloys. That led to the creation of National Aluminum Corporation. The company wasn’t just making beams anymore. It was making components for everything from cars to planes.
Diversification didn’t stop there.
In 1984, they launched GENIX, a subsidiary for computer data and information services. That was cutting-edge thinking in the mid-80s. They also distributed pharmaceuticals and petroleum products. They were a conglomerate before “conglomerate” became a dirty word.
But the biggest shift was international.
Tokyo-based Nippon Kōkan KK started buying in.
In 1984, National Intergroup sold 50 percent of its stake in National Steel to the Japanese firm. It was a massive sale. A half-ownership change.
Six years later, they sold another 20 percent. Same buyer. Same country.
Who bought out the rest? The article doesn’t say. The timeline ends there.
The Weirton Legacy vs. Modern Mergers
Weir’s approach to labor remains a case study in anti-union strategy. Granting raises before a union campaign starts is called “union substitution.” It works until it doesn’t. But it kept Weirton quiet for decades.
Today’s mergers look different. They look more like the Nippon Kōkan deal. Strategic stakes. Partial exits. Global capital.
National Intergroup facilitated this transition. They turned a single steel plant into a diversified holding company.
