A bowing correction apparatus for a temper rolling mill corrects vertical bowing of a cold-rolled steel sheet. The bowing correction apparatus includes at least a first bowing correction auxiliary roll, first deflector roll, second deflector roll and second bowing correction auxiliary roll. These rolls are arranged in the running direction of the cold-rolled steel sheet and are alternately positioned on upper and lower sides of the cold-rolled steel sheet to correct bowing of the sheet.

An uneven patterned metal strip or plate is formed with an uneven pattern as a surface decorative pattern. The pattern is constituted of one or more pattern unit containing a plurality of uneven dot. Each of the uneven dots has a size D. The uneven dots are arranged in a predetermined density to have given ratio .eta. of occupying area versus plane area in said pattern unit. The size D and area ratio .eta. being in a range of:
