Monoblock stopper is one of the important steel flow regulation components, and to meet the particularly demanding operating conditions, we manufacture varieties of stoppers with customised specifications to suit the different designs of our customers' tundishes

To facilitate customisation, during our manufacturing process, we apply different mixtures of aluminia or magnesia to the nose of our stoppers for our customers, enabling them to cast various types of steel.
