The invention discloses a galvanized wire sink roll and belongs to the field of sink rolls. The galvanized wire sink roll comprises a roll body, a groove is formed in the circumferential surface of the roll body, and the groove comprises a left-hand groove body and a right-hand groove body; the left-hand groove body and the right-hand groove body get close to the middle of the roll body from the two ends of the roll body; the groove in the middle of the circumferential surface of the roll body forms a V-type intersecting structure; the left-hand groove body and the right-hand groove body are in the same shape and each comprise a groove trough and a groove crest; the groove crests are provided with transitional sections, and the groove troughs are first circular arc faces; the intersectionsof the transitional sections and the ascending sides of the groove crests are second circular arc faces; and the intersections of the transitional sections and the descending sides of the groove crests are third circular arc faces. Through structural improvement of the groove, the chip removal efficiency is improved, the service life of the sink roll can be prolonged advantageously, and the surface quality of galvanized steel plates is also improved.
