Hot-dip galvanizing is a unique process that protects steel from corrosion by immersing it in a bath of molten zinc up to 450°C.
In the galvanizing process, the metal is smelted into an alloy with the substrate. Therefore, the zinc coating will not peel off like when using paint, creating a permanent protective layer for the metal. The soaking process ensures that the entire surface area of the metal is covered with a single, uniform coating that covers both the protrusions and the inner surface of the sheet metal. The weight and composition of the steel will automatically determine the coating thickness. The galvanized coating will be slightly thicker on the corners and edges of the sheet metal. Galvanized provides superior corrosion resistance. In the event of any damage caused to the surface of the galvanized coating, the sheet metal remains protected by the protective properties of the surrounding zinc coating. Zinc is resistant to environmental corrosion and attack at a wide pH range. For this reason, galvanized steel is widely used in harsh locations such as coastal areas and industrial sites. Depending on the environment, the thickness of the galvanized coating that will be coated is based on a predictable rate of corrosion from 1/17 to 1/80 the rate of the coated steel. Hot-dip galvanizing provides the best barrier protection for steel. It greatly reduces maintenance costs and ensures an extended service life. It reduces the need for energy supply, is 100% recyclable and is an environmental protection solution.
