Q: What is the difference between effective width and width of coil?
A: Width of coil is also called feeding width, refers to the distance between the two edges of the raw material coil.
Effective width or cover/finished width, is the usable width of the material coil after it has been roll-formed, or width of the final product produced by roll forming machine.
Example: The coil’s width of material is 1219mm, going through roll forming machine to produce the panel with effective width of 1070mm.
