EDGES

---

Mokes Steel can supply stainless and cold rolled strip with any one of  six standard edges.  These edges are specified by No. 1, 3, 4, 5, and 6.   The No. 3 edge is included in the base price; extra is charged for the  other edges because of the cost to manufacture.  Minimums will apply  depending on the edge required. 

This is the best edge developed.  It can  be either round or square, but in either case, the finish of this edge  must be equal to the surface finish.  The edge is produced by first  slitting the strip at or near finished thickness.  Then this strip is  passed through the file board to remove burr and to shape the edge.   Another very common method of making No. 1 edge is that of edge rolling  the slit strip with the shaped edge rolls or by using a Turk's head.

There are two types of edges included in the No 1 edge classification: the standard square and the full round edge. 

 A slit edge is produced by an edge  trimming operation.  This is performed by passing the strip through the  slitter. The No. 3 edge is by far the most prevalent edge found on strip  product. 

A finished round edge is produced by edge rolling the strip during cold  rolling and may be manufactured only in those widths and gauges at which  the strip will not buckle during the edging process.  It is used when  an approximately round, but not highly finished edge is desired. 

This is a square type of edge.  It is a No. 3 edge improved by running  the strip through edge rollers for removal of burrs.  This edge is free  from any slitting burr. 

This edge is the same as a No. 4 edge except that it is square rather  than round.  As with the No. 4 edge, the No. 6 edge is not suitable for  electroplating, but is good for painted products.
