We’re making these pieces for a returning customer, they’re CNC cut out of 10 gauge 44W steel and have a few inches of plate marking. Here they are sitting in a muriatic acid bath to strip the mill scale off. Much easier more cost effective to remove the mill scale this method as opposed to using a flapper disc. Besides it leaves a more consistent surface, which is important in this case!
After the acid bath and a light sanding it’s all prepped and ready for a light copper plating.
Finished with a light copper plating and sealing.
