GI products will corrode naturally when exposed to the atmosphere, so pls properly store and transport galvanized steel, don’t damage the zinc coating, otherwise maybe reduce the service life of the hot-dip galvanized products.
if long time stacking galvanized articles closely together or nesting, limiting access to freely circulating air, can lead to the formation of a white powdery product know as wet storage stain.
Wet storage stain is essentially a buildup of zinc hydroxide on the surface of the steel. If the storage condition not dry, this build up will remain on the steel and when mass quantities can cause excessive corrosion finally.
To avoid such situation happen, pls follow the storage terms:
Provide adequate ventilation between stacked layers and avoid nested stacking,check the package whether damaged to prevent water leakage or moisture penetration;
Elevate and separate articles stacked with strip spacers (poplar, ash, spruce); stack less t
