In the production of galvanized steel on a continuous galvanizing unit, the adhesion strength of the coating to the cold-rolled steel strip visually and during random tests on samples is satisfactory. When stamping products made of galvanized metal, zinc delamination occurs. It is necessary to develop a quality control technology for the adhesion of zinc with cold-rolled steel strip in the production flow. "1. Type of product - galvanized steel: 2. thickness - in the range from 0.25 to 3.0 mm, 3. width - in the range from 900 to 1320 mm, 4. maximum strip speed - up to 240 m/min,
