Abstract

PURPOSE:To lighten the weight of a structure and to save operating energy by forming specific shape ribs continuing in the sheet length direction on at least one of the top and bottom surfaces in the sheet width direction. CONSTITUTION:A steel stock heated by a furnace 10 to facilitate rolling is rolled to have a specific sheet thickness at the start of caliber rolling by a rolling mill 12 provided with flat work rolls 1, 2. Then, the stock is fed to a rolling mill 13 provided with caliber rolls worked into a frustum shape as rolls 1, 2 at the rib forming side and is subjected to several times caliber rolling with sheet width adjusted by a sheet width adjuster 4 to obtain a ribbed steel sheet 5. In that case, it is necessary that a ratio of a ribbed part thickness to a non-ribbed part thickness is >=1.2, a rib height is >=5.0mm, and the number of ribs continuing in the sheet length direction in the sheet width direction, is made plural.
