Abstract: This coated metal sheet is for exterior covering, and has a metal sheet and a top coating layer disposed on the metal sheet. The top coating layer is configured from a fluororesin and contains 0.01-15 vol % of microporous particles as a gloss control agent, and the coated metal sheet satisfies the belowmentioned formulae. In the belowmentioned formulae, in the number-based particle size distribution of the gloss control agent, R is the number average particle size (μm), D97.5 is the 97.5% particle size (μm), Ru is the upper limit particle size (μm), and T is the top coating layer thickness (μm): D97.5/T≦0.9; Ru≦1.2T; R≧1.0; and 3≦T≦40.

Abstract: This coated metal sheet for exterior covering has a metal sheet and a top coating layer disposed on the metal sheet, the top coating layer is configured from a fluororesin and contains a gloss control agent comprising 0.01-15 vol % of microporous particles and a matte agent comprising primary particles, and the coated metal sheet satisfies the belowmentioned formulae. In the number-based particle size distribution of the gloss control agent and the matte agent, R is the number average particle size (μm) of the gloss control agent, D197.5 and D297.5 represent the 97.5% particle size (μm) of the gloss control agent and the matte agent, Ru is the upper limit particle size (μm) of the gloss control agent, and T is the top coating layer thickness (μm). D197.5/T≦0.9 Ru≦1.2T R≧1.0 0.5≦D297.5/T≦7.0 3≦T≦40.
