    Hot Rolled Strip Steel

    The guaranteed strength and good weldability of our hot-rolled structural steel help ensure ease of processing and reliable end-product performance.

    As with all our hot-rolled steel products, our structural steel is manufactured under tight controls – for consistent quality that you can depend on.

    Ympress® for weight savings and component strength

    Ympress® is Tata Steel’s hot-rolled HSLA product. It is highly formable and delivers weight savings and increased component strength. The result is lighter, stronger, more consistent products.

    Ympress® adds value to automotive, lifting and excavating and shipbuilding applications, among others.
