During the production of stainless steel steel grating, black oxide scale is produced through processes like pressing and welding, and cutting. The surface requires secondary treatment, which is generally done in three methods: 1. Acid pickling, resulting in a matte gray-white surface. 2. Electrochemical polishing, which yields a brighter surface. 3. After heat treatment and polishing, the product undergoes electrochemical polishing and chrome plating to achieve a mirror-like finish.
