Yes. Plate billets are not perfectly square to begin with, and their edges become even more irregular after hot rolling. Therefore, to ensure the plates are square, we slit the edges during the final finishing stage.

Pickling is a chemical surface treatment process for plates. The main step involves fully immersing the plates in a highly corrosive acid solution (such as a mixture of hydrochloric acid, sulfuric acid, or nitric acid) for a specified period of time. The acid solution reacts chemically with the scale, rust, and microscopic impurities formed on the plate surface during hot working or heat treatment, dissolving or stripping them away.

Yes, we can. If you require a shot-blasted surface, please let us know in advance, and we will add the shot-blasting process after pickling. Compared to pickled surface alone, shot-blasted surface has a higher surface roughness and a more uniform matte finish, which improves the adhesion of subsequent coatings and helps eliminate surface tensile stress caused by welding or hot working. However, shot blasting does increase processing time and cost. The specific process can be customized according to your technical requirements.

Yes, we can. We have large-scale polishing equipment for plates and can polish the plates on one or both sides. The polished surface is bright and uniform, meeting the needs of applications with high requirements for aesthetics or cleanliness. Please confirm the specific polishing requirements with us in advance.
