Problems solved by technology

[0003] However, if a resin-containing coating film is formed on the surface of the stainless steel sheet, cracks or whitening may occur on the coating film over time, and the design property may be easily impaired.
Also, wax or oil needs to be reapplied periodically

Abstract

The purpose of the present invention is to provide a coated metal plate that has excellent stain resistance, that does not cause interference patterns to occur, and that has excellent design properties. This coated metal plate comprises a metal plate having an average surface roughness Ra(metal plate) of 0.40 [Mu]m or less and a coating film that is formed on at least one surface of the metal plate, that substantially comprises a composition represented by the compositional formula K2O-xSiO2 (3.5<=x<=6.8), and that has an average thickness t of 0.2-3.0 [Mu]m. The average thickness t of the coating film and the average surface roughness Ra(coating film) of the coating film satisfy formula (1). Formula (1): Ra(coating film)>=0.03 / t+0.15.

Description

technical field [0001] This invention relates to coated metal sheets. Background technique [0002] For door materials and operation panels of conventional elevators, etc., stainless steel sheets with improved design through etching, coloring, or surface treatment, etc., are used. These stainless steel sheets are required to be resistant to adhesion of fingerprints and the like, to have high stain resistance, and to have high scratch resistance. Therefore, generally, a coating film containing resin, wax, or oil is formed on the surface of the stainless steel sheet. [0003] However, if a resin-containing coating film is formed on the surface of the stainless steel sheet, cracks, whitening, etc. will occur on the coating film over time, and the design property will be easily impaired. Additionally, waxes or oils require periodic reapplication. [0004] Therefore, studies have been made to form a coating film containing an inorganic material on the surface of a stainless st...
