What is Surface Finish? Before we go into the surface finish chart, let's understand what surface finish entails. Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay.
