Production batch management manner null of the metallic plate which can point to the color tone difference at the time of interior and exterior application

摘要

PURPOSE: To reduce color tone difference in the time of execution of interior and exterior works by sticking a protective film on which marks indicating the rolling direction are printed on a metal sheet and arranging those direction marks in the time of execution of the works. ;CONSTITUTION: In the final manufacturing stage of a dull finished stainless steel sheet, the protective film on which arrow marks are printed at the pitch of 245mm in the width direction and at the pitch of 150mm in the longitudinal direction is stuck on the steel sheet. In this sticking, the direction of the arrow on the protective film and the dull rolling direction of the dull finished stainless steel sheet are agreed with each other. When this dull finished stainless steel sheet is worked to metallic roof tiles and the roof tiles are applied to a building roof, the work is executed so that the tiles are arranged in the direction of this arrow and as a result, the building roof can be finished into a roof uniform in color tone. Concerning the printed arrow, the size and interval of the arrow can be decided arbitrarily by the size of the stainless steel sheet.;COPYRIGHT: (C)1994,JPO&Japio
