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, D1and D2represent 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).1≤0.9Ru≤1.2TR≥1.00.5≤2≤7.03≤T≤40.
