It has been established, that a breakdown degree of 10 to 20 % was admissiblefor roll forming. The damage and further destruction of the coating occurs in sheets having coating thickness exceeding 50 mcm. The contact interaction model enables tocompare the level of contact stresses and degree of breakdown.
