Performance of Hot-Dip Galvanized Steel Products

Corrosion damage and its repair represent multi-billion dollar issues. According to estimates, metallic corrosion costs US $297 billion yearly or roughly 3% of the GDP. Although corrosion is a natural occurrence that cannot ever be totally eradicated, using effective corrosion prevention systems in severe situations can significantly lower the expenses.

After fabrication, hot-dip galvanizing is a maintenance-free, cost-effective corrosion protection method that endures for decades even in the harshest situations. Hot-dip galvanized steel has been widely used for more than 100 years to prevent corrosion in significant industrial settings, including petrochemical, transportation, and public utilities.

The zinc of the hot-dip galvanized coating is more corrosion resistant than bare iron and steel. In the same way that steel corrodes when exposed to air, so does zinc, but the rate of corrosion is around 1/30 of that of steel. The corrosion rate of zinc varies based on its environment, much as it does with steel. As a result, different environments have different effects on how hot-dip galvanized steel performs.

Galvanized steel is frequently used in indoor and outdoor settings, the storage of hundreds of various chemicals, soils, concrete, and/or in combination with other metals, treated wood, and high or low temperatures, among other environments. Galvanizing has been used for corrosion prevention for a very long time, therefore there is a lot of real-world, long-term exposure data on the performance of zinc coatings in a range of situations. Given the wide range of uses for hot-dip galvanized steel, it's critical to comprehend the variables that determine how well it performs in each of these settings.
