The hairline grain is brushed into the coil first, then the entire coil runs through a continuous PVD coating line on German-imported equipment — a vacuum deposition process that builds an ultra-thin gold film, typically under a micron thick.

Gold blasted stainless steel starts with the same PVD gold coating used across our gold finishes, but the surface underneath is blasted rather than brushed or mirror-polished — media is propelled at the base under pressure to strip away reflectivity before the coating goes on.

The size of that media is what separates the two textures: fine glass or ceramic beads on a pre-polished base give bead blasted gold a smooth, even matte with a soft sheen (Ra 1.5–2.5μm), while coarser zirconia or aluminum oxide media on a standard base gives sand blasted gold a rougher, fully matte texture with no sheen (Ra 4–7μm).

Either way, because the PVD layer is only microns thick, it settles into the blasted texture rather than filling it in, so the matte grain stays visible under the gold rather than being smoothed away.
