Zusammenfassung:The invention relates to the technical field of steel and iron, in particular to thin-gauge steel for an elevator, a ferrite area rolling process of the thin-gauge steel and application. The steel for the elevator comprises the chemical components of 0.01%-0.05% of C, 0.01%-0.05% of Si, 0.10%-0.50% of Mn, smaller than or equal to 0.015% of S, smaller than or equal to 0.015% of P, smaller than or equal to 0.006% of N, smaller than or equal to 0.0030% of Ti, smaller than or equal to 0.0035% of Nb, 0.015%-0.040% of Alt and the balance Fe, the matrix structure is ferrite and cementite, and the thickness is 0.9-2.0 mm. The ferrite area rolling process comprises the steps of raw material selection, headless strip steel rolling and acid pickling flattening. The thin-gauge steel for the elevator can be used for manufacturing an elevator landing door. The mechanical property and the machining plate shape of the thin-gauge steel for the elevator are guaranteed through stable ferrite area rolling, and the purpose that c
