Camber strips shall not exceed: 

- Strips width up to 100 mm inclusive - 4 mm to 1 m length 

- Strips width over 100 mm - 3 mm to 1 m length 


Camber strips) up to 4.0 mm, should not exceed 5 mm to 1 m in length, thickness exceeding 4,0 mm - 8 mm to 1 m in length. 


Internal coil diameter - 100 mm, 250 mm, 300 mm, 400 mm and 500 mm (depending on thickness and width of the strip, negotiate with the customer when ordering). 


The maximum weight a roll with a width of 600 mm to 1100 kg. 


Surface quality: 

The surface of the tape must be clean.  On the surface, allowed discoloration, local darkening traces of technological lubricants, as well as local defects, not putting out tapes for control over clean-up tolerances in thickness.
