Introduction to GI Coil Codes
In general, Z stands for pure zinc coating and ZF refers to zinc-iron alloy coating. The number represents the thickness of the zinc layer. For example, Z120 or Z12 means the weight of zinc coating (double-sided) per square meter is 120 grams. While the zinc coating of the single side will be 60 g/㎡. Below is the recommended zinc layer thickness for different use environments.
How to Choose Base Metal Based on Applications?
Appearance
The color of the galvanized steel coil is silver-white. The appearance of cold galvanized steel is smooth but not very shiny, while the hot-dip galvanized steel coil looks rough but bright.
Production Cost
HDG process consumes more zinc. Compared with hot-dip galvanized steel, the production cost of electro-galvanized steel is lower. But hot-dip galvanizing is suitable for massive production and the yield is high. So the HDG steel price is not much higher than cold galvanized steel.
