The First Minister will re-open Tata Steel's site at Llanwern this afternoon after the company invested £3.6million in its Zodiac plant.
The aim is to offer more flexibility to customers in the automotive sector as they try and expand the business and reach new markets.
Jon Ferriman, Director of the Port Talbot and Llanwern steelworks, said: "The investments we have completed recently, including the Zodiac upgrade, are all intended to improve the sustainability and competitiveness of the South Wales steel industry in extremely challenging times."
Meanwhile GDP figures are out later this morning and are likely to show a small rise, mostly due to improvements in the manufacturing and construction sectors.
