1, Internal coil diameter is nominally 508 mm.

2, Maximum coil weight is 20 tonnes or 20, 0 kg per mm coil width. Maximum coil outside diameter is 1850 mm.
3, Thickness tolerance and other geometric characteristics
Non-oriented fully processed electrical steels meet all the requirements on thickness tolerance and other characteristics such as edge camber and flatness as specified in the standards EN 10106 and IEC 60404-8-4.
4, Thin non-oriented grades are available at the nominal thicknesses, 0, 27 mm, 0, 20 mm, 0, 18 mm, 0, 12 mm and 0, 10 mm. All are fully processed non-oriented electrical steels, especially suited for use at medium to high frequencies (typically 200 3000 Hz).
