ABSTRACT In a process in which strip metal is subjected to heating while suspended as a catenary in a heating zone, the strip is passed into the heating zone in a condition in which the lower surface is slightly elongated in relation to the upper surface. The differential elongation may be by a roller leveller or equivalent mechanism during passage conveniently employed to control edge creep and improve flatness in storing coated strip or in annealing operations.
