Color-coated coils are made from cold-rolled steel strip. Galvanized steel strip is made from galvanized steel sheets (electrogalvanized or hot-dip galvanized). After surface pretreatment (degreasing and chemical treatment), one or more layers of organic coating are applied by roller coating, followed by baking and cooling.

Improper storage of color-coated steel coils can lead to defects such as scratches, dents, and rust, which can even cause serious consequences. To ensure the quality of color-coated steel coils, careful storage is essential.

Store them indoors in a clean, dry, and well-ventilated environment. Avoid outdoor storage or locations prone to condensation or temperature fluctuations. The storage surface must be flat, free of hard objects, and have sufficient load-bearing capacity. Coils should be placed upright on rubber mats, wooden pads, or supports, with the buckles facing upward. Thick plates and coils should be stored properly for easy access and to minimize unnecessary movement. Stacking is strictly prohibited to prevent damage, and stacking height must be strictly limited.
