All of our rings are inspected for required Tolerances on Dimension and Finish during manufacture. All steel used for the manufacture of ring bodies is traceable and material certification for all components used in the finished product can be made available if required.
During our rolling process we print on the inside of the ring both material tracing information and date of manufacture. This could be printed on the outside of the ring should customers wish. We can print any text required by customers. Click on the thumbnail opposite to open a new window containing a larger sized image.

Internal Printing

All of our rings are de-burred during manufacture. This minimises the slitting burr which is always present after steel coil is slit into narrow widths (Which is our stock raw material). This greatly reduces the potential for our rings to cause injury to operators during handling.

The majority of our rings have the sharp corners removed. These corners are caused by the cropping of the ring to length after rolling. We replace this corner with a smooth radius. Again, this reduces the potential for rings to injure operators. Click on the thumbnail opposite to open a new window containing a larger sized image.

Ring Ends

All processes employed to produce rings are tested for first off and last off compliance. Regular sample checking is used throughout production. This ensures a consistency of product for our customers.
