DM Metalloys Pvt. Ltd. leading manufacturer, exporter and supplier of stainless steel NO.4 finish in 304/304l/316/316l coils. No 4 finish stainless steel is the mainstay of the light fabrication industry. The easiest of the appearances to maintain, No 4 finish is used for work surfaces, bannisters and where appearance is important. A 'No 4' surface is shaped by cutting the surface with abrasive belts to remove a very small amount of metal without affecting its thickness. This is a ground unidirectional finish obtained with 150 grit abrasive. It is not extremely reflective, but is a good general purpose finish on mechanisms which will suffer from fairly rough handling.
