1. Types of coils packaging
There are two types of coils packaging. One is the pre-packaging. It asks workers to tie up the coil with 1 to 3 steel strips. Generally, it fits for the hot rolling and chill coils, as well as those coils transported in short-distance and good condition. The other one is precision packaging. And it requests workers to wrap the coil with different packing materials to finalize the design. It suits the cold rolled steels, especially for silicon steels.
2. Packing materials.
There are many kinds of packing materials, such as anti-rust papers, plastic bags, inner algams, outer algams, inner paper angle beads, outer paper angle beads, endshields, inner iron angle beads.
The effect of packing materials is as follows.
It has dual anti-corrosion performance. And the composite structure is more than 3 layers, which could prevent corrosion, as well as water leakage and moisture.
It wraps the surfaces of anti-tarnish papers to prevent waterproof.
Inner and outer algams.
It protects the coils, anti-tarnish paper and plastic bags.
Thick plastic plates.
