The line closure is due to happen in the summer Read this story in Welsh

The company says its electro-zinc line is a dying market, and it wants to focus on other markets and products.

The workers will be eligible to apply for jobs in a new part of the business in Shotton, making factory built homes.

And the company says staff who want to leave will also be offered help to find work outside the company.

Decline

A spokesman for Corus said the electro zinc market is in terminal decline, and has dropped by 20% in the last 2 years.

He said the company wants to focus on markets and products which have a future.

Alyn and Deeside MP Mark Tami said he was "extremely upset" by the announcement, but is hopeful that compulsory redundancies will be avoided.

He added that the closure of the line was not due until late summer, which meant there was a four month period to minimize the impact on the workforce.

It is a severe blow for Corus employees, who managed to avoid a round of job cuts at its Llanelli and Port Talbot plants in April.

The Corus plant in Port Talbot is to become a centre of excellence

A total of 1,150 jobs were lost at the time, mainly at the steel works plant near Rotherham.

But production at Port Talbot is to be increased by around 25%, making it one of the main steel producing centres in the country.

Around 35 extra jobs will be created at the plant, which employs 3,000 people directly and a further 5,500 workers through contractors.

But staff at the site in Shotton, who were told the news on Tuesday morning, did not manage to avoid the job cuts.

Decline

Mike Jeffreys of the Transport and General Workers' Union condemned the move.

"We are appalled that once again the management of Corus, who have turned a highly profitable company into a debt-ridden operation, are pursuing a policy of decline...

"... which is resulting in job losses for the most productive steel workers in the world.

"Today's news is a severe blow to members at Shotton and causes further uncertainty for workers throughout Corus.

"We are seeking urgent talks with the company over this further round of job cuts."
