No.4 Stainless Steel Sheet
The characteristic of a No.4 finish panel is its finely polished sand grain texture, presenting a uniform appearance with directional qualities. It features a smooth, velvety, and resilient coating. Its processing technique is similar to that of a brushed finish, employing a sanding drum to provide a delicate texture. The distinction lies in the longer hairlines of the brushed finish, while the #4 Finish exhibits shorter and finer lines, even displaying a rainbow-like reflective effect from certain angles.
