Method of coating metal strips, preferably made of steel or aluminum, by applying a powder coating, cleaning, and baking, where 1) the powder coating comprises at least one polyhydroxy-functional resin or at least one epoxy resin, and 2) the powder coating has a particle size distribution such that a) at least 90 percent by mass of the powder coating particles have a size of between 1 and 150, preferably 1 and 100 mum, b) the maximum size of the powder coating particles for at least 99 percent by mass of the particles is <=150 mum, c) the mean size of the powder coating particles is between >5 and 60 mum, preferably 5 and 40 mum, and d) the slope of the particle distribution curve at the point of inflection is >=50, preferably >=100.
