How To Store GI Coil Properly?

The storage of GI coil is also learned. If it is not stored properly, it will rust and become moldy during storage. Due to the humid air, galvanized strip steel is easy to form oxidation with the air, and it will naturally rust and mold after a long time. Specific requirements for storage of GI coil: First, the surface of galvanized strip steel should be treated. If the surface of the galvanized strip is not clean, in some cases the surface will be oxidized.

GI coil is a very functional material, so we must ensure its integrity when storing it. If there are some hard substances in the environment we choose, they should be cleaned immediately to ensure that these hard substances will not cause friction and collision with the galvanized steel panel. A ventilated and dry place is very beneficial to the storage of galvanized steel sheets. On the contrary, a humid place is not conducive to the storage of galvanized steel sheets, because galvanized steel sheets are prone to rust in such an environment.

Galvanized steel strip must be stored in the correct manner and such products must be stored in categories. Please note that the storage methods of hot-dip galvanizing and electro-galvanizing are different. For hot-dip galvanized products, the zinc layer is generally thicker, so even if there is rust, it will not have a big impact, so the storage requirements are not so strict. Galvanized strip steel has very strict requirements for electro-galvanizing, because its zinc layer is very thin, once oxidation is found, it should be dealt with in time.

GI coil is divided into hot-dip galvanized and galvanized. The storage method is also different. The hot-dip galvanized zinc layer is relatively thick, so if it rusts, it will not have too much impact on the galvanized strip steel, and it will not affect the normal work, so the storage method is not very strict. However, the galvanized zinc layer is very thin. If oxidation occurs, it is best to deal with it in time, and pay attention to cleaning of the surface of the galvanized strip. At the same time, when the galvanized strip is stored, the air in the storage place should not be too humid and should be stored in a ventilated place, so as to ensure the quality of the galvanized strip. If white rust is found on the surface of the galvanized strip, there is no need to be nervous. Because zinc is oxidized in the air, it can be handled normally.

Under normal working conditions, the thickness of the galvanized layer of the hot-dip GI coil is greater than 50um, which can be used safely for 30 years. This is based on the anodic protection principle of the iron substrate. This method of hot-dip galvanized sheet makes the pure zinc layer produce a dense protective film in the atmospheric environment to prevent zinc corrosion. However, if we encounter a wet environment, we will prevent the corrosion and perforation of the zinc coating by coating asphalt or sealing the groove to isolate the direct contact between the medium and the zinc coating.
