Coarse Ground

A coarse abrasive finish with a unidirectional grain often applied as a key for paint or for bonding purposes.

Generally produced with an aluminium oxide abrasive with grits between 60 > 100.

On standard cold rolled sheet a Coarse Ground finish produces a surface roughness of approximately 2.5┬Ám Ra conforming to BS EN 10088-2 2G Finish. Under the old BS 1449 Part 2 specification this was a 3A finish.

We can apply a Coarse Ground finish onto the following products.

Please be aware that the above refers to the finish produced on cold rolled sheet. On other products different readings may result depending on the performance of the substrate.
