Staff at a Derbyshire ironworks are facing an uncertain future after managers announced the workforce was to be cut by half.
More than 200 jobs are expected to go at pipe manufacturer Stanton Ironworks which is run by Saint-Gobain Pipelines.
The Ilkeston factory makes iron pipes for the water industry, but the company said this work would be moved overseas.
It blamed a steady decline in the market, along with major increases in the cost of steel for the move.
In a statement, Saint-Gobain said some departments would stay at the site but about 220 jobs would have to go as part of the new plans.
The statement added: "We very much regret any job losses and our priority is to support our employees at a difficult time."
Production is expected to end in April 2007.
A spokesman from workers' union Amicus, said the latest round of cuts brought the number of recent job losses in the region to more than 1,000.
