Australia’s BlueScope Steel and Japan's Nippon Steel Corporation have agreed a long-term joint technical collaboration to develop next-generation coated steel products.

Nippon Steel said in a statement that the products would be for the global building and construction market.

"Under this collaboration, both parties will conduct further joint research and development utilising each other's facilities for research, production and processing," it said.

‘‘The new product technologies will improve corrosion resistance performance, formability, and surface clearness, compared to the current product,’’ it said.

‘‘Both companies will announce expected market launch timeframes in due course.’’
