A simple 2000 liter tank out of 2B material might require 100 man-hours to fabricate with basically passivated welds, 120 man-hours with the welds dressed to 180 grit both sides and 200 hours with the inner welds finished to 600 grit, which would be an appropriate spec. prior to electropolishing the inner surface. With the entire inner surface mechanically mirror polished, the man-hours become 350 provided no subsurface imperfections are encountered. 180 grit is a similar surface roughness to No. 4 polish but the same uniform lustre is almost impossible to achieve. With the inner and outer surfaces mirror polished, the man-hours leap to over 550, unforeseen imperfections not withstanding. That is an expensive look and if a firm quote is required to produce it, how can the unknowable but possible problems be allowed for? The reality is they cannot with certainty. If it's of any help, we have a highly developed program that operates as stand-alone software. It asks for the surface finish required and calculates the necessary labour cost
