An abrasive finish with a unidirectional grain produced with a silicon carbide abrasive with an approximate grit of 240. Due to the nature of polishing with silicon carbide the finish results in a ‘clean cut’ grain ideally suited to external architectural, pharmaceutical and catering applications. Surface is smoother than a Satin Polished finished but not as fine as a ProLustre Finish.
On standard cold rolled sheet a 240 Silicon finish would produce a surface roughness of approximately 0.3µm Ra conforming to the BS EN 10088-2 2K Finish. Under the old BS 1449 Part 2 specification this was a N0. 5 finish.
We can apply a 240 Silicon finish onto the following products:
Sheet, Plate, Flat & Square bar, Square & Rectangular tube, Blanks, Coil, Lasercut profiles
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.
