The Argentina customer want to know whats the sizes of the purlines feeding strips width for his 8 size purlines.
Below is the calculating method of the C Purline:

As take above C drawing for an example:
The feeding width W is h plus b plus b plus d plus b subtract 2.0 subtract 2.0 subtract 2.0 subtract 2.0
For example, the C purline 100x45x15x2.0 , the feeding strips width is:
100+45+45+15+15-2-2-2-2 =212 mm
The C purline calculating method is as above mentioned. If you want to know more about other C purlines calculating method and the Z purlines calculating method, kindly contract me, please, i will tell you the exactly calculating method which can help you to by the exactly size the strips as the raw material.
