The Galvano-Annealed GA/Zincro Coils are supplied by us that are made available by us for use in the various industries. The coil slitting line is used to create smaller coils to a specific width or weight. A master coil will be threaded into the slitting line and from there a coil will be formed to your desired width. Cold rolled steel in the form of coiled sheets requires heat treatment (annealing) in order to release stresses and reform the crystalline structure. The coils are made for use in the various industries and have efficient design. They are easy to install.
