How long is the storage time of hot-dip galvanized steel angle in natural conditions?
Hot-dip galvanized steel angle storage environment, if more humid, the galvanized layer will produce corrosion, the formation of "white rust", so that the angle loses its metallic luster, seriously affecting the appearance of the quality, so the storage process also need to do a good job of protection.
Hot-dip galvanized steel angle has a glossy surface, zinc layer uniformity, no leakage plating, no dripping, strong adhesion, strong corrosion resistance, in suburban environments, the standard hot-dip galvanized rust thickness can be maintained for more than 50 years without the need for repair; in the urban area or offshore area, the standard hot-dip galvanized rust layer can be maintained for 20 years without the need for repair.
Angle steel in a humid environment, stacking, rain during transportation, surface corrosion in the polluted atmosphere, and so on, are the cause of "white rust". Angle in the storage process, do not pile up too high, or in the angle between the pad, can effectively prevent the "white rust", this is because the white rust is often due to the workpiece tightly stacked between the surface of the water droplets or water film caused by condensation. In the acid, steam, seawater waves and other corrosive environments, "white rust" will intensify. Angle steel stacking and storage and transportation process, in addition to preventing "white rust", but also pay attention to collision scratch galvanized layer.
