Abstract: A method of forming a metal coated steel strip that has a brushed finish is disclosed. The method includes skin pass rolling a metal coated steel strip to suppress and/or obscure the spangles on the surface and thereafter brushing the skin passed rolled strip.

Abstract: A method of controlling “rough coating” and “pinhole-uncoated” surface defects on a steel strip coated with a aluminum-zinc-silicon alloy. The alloy has 50-60 % wt Al, 37-46 % wt Zn and 1.2-2.3 % wt Si. The method includes heat treating the steel strip in a heat treatment furnace and thereafter hot-dip coating the strip in a molten bath and thereby forming a coating of the alloy on the steel strip. The method is characterized by controlling the concentration of (i) strontium or (ii) calcium or (iii) strontium and calcium in the molten bath to be at least 2 ppm.
