Abstract: This coated metal plate is a chromate-free coated metal plate for exterior applications, which comprises a metal plate and a coating film that is arranged on the metal plate. The coating film contains 0.01-15% by volume of porous particles as a gloss control agent. If R (μm) is the number average particle diameter of the gloss control agent, T (μm) is the film thickness of the coating film, and σ is the standard deviation of the number-based particle size distribution of the gloss control agent, the coated metal plate satisfies the following formulae. (R+2σ)/T≦0.7 R≧2.0 9≦T≦19.

Abstract: Provided is a coated metal sheet for exterior use, having a metal sheet, and a top coat film situated on the metal sheet. The top coat film contains 0.2-15 volume percent of a gloss control agent composed of porous particles and a delustering agent composed of primary particles. The coated metal sheet satisfies the following expressions in which, in the number-size distribution of the gloss control agent and the delustering agent, R is the number-average particle diameter (μm) of the gloss control agent, D197.5 and D297.5 are 97.5% particle diameter values (μm) of the gloss control agent and the delustering agent, Ru is the upper limit particle diameter (μm) of the gloss control agent, and T is the film thickness (μm) of the top coat film. D197.5/T≦0.7 Ru≦1.2T R≧1.0 2.0≦D297.5/T≦7.0 13≦T≦20.

Abstract: This coated metal plate is a chromate-free coated metal plate for exterior applications, which comprises a metal plate and a coating film that is arranged on the metal plate. The coating film contains 0.2-15 vol % of porous particles as a gloss control agent, and contains 0.2-15 vol % of primary particles as a matting agent. If R1 (μm) is the number average particle diameter of the gloss control agent, R2 (μm) is the number average particle diameter of the matting agent, T (μm) is the film thickness of the coating film, σ1 (μm) is the standard deviation of the number-based particle size distribution of the gloss control agent and σ2 (μm) is the standard deviation of the number-based particle size distribution of the matting agent, the coated metal plate satisfies the following formulae. (R1+2σ1)/T≦0.7 R1≧2.0 2.0≦(R2+2σ2)/T≦7.0 13≦T≦20
