G90 galvanized steel has a longer service life than G60, G40, and G30 galvanized steel, because G90 galvanized steel has a heavier coating weight of zinc applied to it at 0.90 oz/ft^2 as opposed to G60 galvanized steel at060 ox/ft^2 and so on. The aforementioned zinc coating weights of galvanized steel are controlled by steel mills during the production cycle and vary depending on customer requirements and the ultimate end use of the product. In previous steel making generations, galvanized steel sheet used to contain large, flowery crystalline patterns of zinc on the surface of the steel known as “spangle”.
Once the steel is cleaned and its scale is removed, it is continually submerged in bath of molten zinc forming a metallurgical bond and protective coating at a controlled coating weight. This coating increases a steel coil’s, slit coil’s, or sheet’s resistance to corrosion. Zinc Coated Gi Galvanized Steel Strip Coil Zinc Coating 30-275 g/m2.
Usually galvanized steel sheet and galvanized steel coil process and specifications are basically the same. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. Hot Dipped Galvanized Steel Sheet’s specifications is thickness(0.14-1.0mm), width(600-1250mm).
Offers Carbon Steel Flat Roll products by Coil (Master and Slit) and by Sheet (full sheets and precision blanks). Cold rolled steel sheets hot dipped galvanised. We supply steel sheets and strips without surface treatment, hot dip galvanised, electrogalvanised, varnished, Aluzinc and Alusi sheets and strips.

Our photo (above-left) shows silver-colored water supply piping that is probably galvanized iron. Galvanized iron water supply pipe can also burst from freezing, and may split at seams depending on how the pipe was manufactured. Life expectancy of galvanized iron or galvanized steel water piping.

Galvanized Iron Water Supply Piping, & Galvanized Drain Piping. The new pipe restores the flow of the pipe to maximum pressure and prevents further spread of corrosion or leaching of lead into the potable water. Moreover, galvanized pipes began to be used after it was discovered that lead pipes could cause lead poisoning due to leaching of lead into drinking water.
