NO. 4 FINISH Print

No 4 finish stainless steel is the workhorse of the light fabrication industry. The easiest of the finishes to maintain, No 4 finish is used for work surfaces, handrails and where appearance is important.

A ‘No 4’ surface is produced 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 highly reflective, but is a good general purpose finish on components which will suffer from fairly rough handling in service.
