What is a coil?
In order to save space, finished plate metals are wound into coils (roll/reel). This helps to store large quantities. Even plate metals up to 25 mm thick are stored as coils. It does not matter whether it is hot- or cold-rolled plate metal.
Because plate metal is more likely to be supplied as sheet material, decoiling equipment is necessary. These are used to unwind the coils and cut them into parts or into the usual metal plate formats.
