The strip edge can have a major impact on the end result of processing, such as how easy the cold-rolled product is to form. For example, tight width tolerances mean strips can be processed without having to trim the edges, therefore increasing output. This requires first-rate edge finishing. The BILSTEIN GROUP supplies its products with the following edges:
• Mill edge (NK)
• Slit edge (GK)
• Custom edge (SK)
With regard to custom edges, a distinction must be made between rolled and skived edges. For mild and unalloyed steel strips, the ability to produce custom edges during production is restricted to the skiving process; high-strength and tempered strips allow extremely precise and more varied edge treatments.
The following custom edges are available as standard, with additional options available on request:
