How to deal with the deviation of Galvanized steel coil (GI) printing process?

In the rolling process of Galvanized steel coil (GI), more and more printing process is used. By embossing and printing process, different surface effects can be obtained, which overcomes the problem of rolling surface of galvanized steel coil. The shortcomings of easy discoloration, delamination, and unsightly appearance, time-saving and labor-saving, low production cost, not easy to fade, anti-aging, good fire and rain resistance, make up for the shortcomings of ordinary steel coil rolling surface monotonous.

The difference between galvanized and Galvalume steel coil (GL)

The difference between galvanizing and Galvalume steel coil (GL) mainly lies in the difference of coating. The surface of galvanized steel coil is evenly distributed with a layer of zinc material, which plays an anodic protection role for the base metal, that is to say, the replacement of zinc material Corrosion protects the use of the base metal, and only when all the zinc is corroded can the base metal inside be damaged.
