Rolled or obtained by steady casting means a process that casts molten steel instantly into semi-finished shapes. Hot drawing is a process the place metal is heated and passed by way of a die to supply the finished shape. Flat rolled products with a width less than 600 millimetres are included. Flat rolled products with a width 600 millimetres or more are included. Ribbed products with an angular profile are excluded and are classified underneath heading 7216.
