Electrical steels are produced with insulation on both sides or without insulation.

Weight of coil or strip - max. 16,5 mt (outside diameter max. 1600 mm)

in dependence on the grade, width and type of seating (vertical or horizontal axis, wooden palette, without wooden palette, etc.)

Packaging

Coils and strips are packed according to USSK packaging rules.
The packing can be adapted according to customer requirements
Strips are delivered with a horizontal or vertical axis on wooden palletes or on special metal skids.
Coils are delivered with horizontal axis on wooden palletes or on special metal skids.
