Yes. By default, the bright bars we supply are polished. If you have strict requirements for both dimensional tolerances and straightness, we can produce bright bars through grinding. Please note that ground bars will be priced higher.

No problem. Under standard delivery conditions, we do not perform chamfering by default, as most customers handle this themselves during subsequent processing. However, to meet the individual needs of our customers, we are equipped with a full range of machining and chamfering equipment and are fully capable of chamfering both ends of round bars. Simply provide the specific chamfering parameters (such as angle, length, or drawing requirements), and we can incorporate the chamfering process during production to ensure the product is ready for immediate use upon arrival without the need for secondary processing.

Polishing is a machining method that uses high-hardness grinding wheels or sanding belts to mechanically grind the surface of round bars. The purpose is to remove surface scale, fine scratches, or other defects, thereby achieving a brighter, smoother metal surface. In actual production, a layer of black scale typically remains on the surface of hot-rolled round bars, which must be removed through polishing to reveal a uniform metal substrate.

Grinding is a process that involves using abrasive tools with a higher hardness than the bar material to perform micro-cutting on the surface, thereby achieving a bright finish. When customers require high tolerance grades for the bars (such as H6, H7, or stricter), grinding is a key method for ensuring precision. Additionally, the grinding process typically requires the bar to rotate during machining, so the bar’s initial straightness directly affects the grinding results.
