Hot Dip Galvanizing Process Overview
Hot Dip Galvanizing is a comprehensive process that ensures the durability and protection of steel products. The process involves several critical steps that contribute to the final quality of the galvanized product.
- Cleaning Cycle: The first step in Dip Galvanizing is the cleaning cycle, which includes degreasing, rinsing, pickling, and rinsing again. This step is crucial as it prepares the steel surface by removing any dirt, oil, or other contaminants that could affect the quality of the galvanization.
- Fluxing: Following the cleaning cycle, fluxing is performed. Fluxing is the final surface preparation step in the Hot Dip Galvanizing process. It effectively removes any remaining oxides from the steel surface and prevents new oxides from forming before the material is submerged in molten zinc.
- Galvanizing: In this vital step, the steel product is completely immersed in a bath of molten zinc, which is maintained at approximately 840°F (449°C). The Hot Dip Galvanizing process ensures that the zinc metal reacts with the iron on the steel surface to create a robust zinc/iron intermetallic alloy. This alloy provides superior protection against corrosion, extending the lifespan of the steel product.
- Post-Treatment: After galvanizing, post-treatment processes such as quenching and passivation are applied. These steps ensure the galvanized steel’s surface is uniform and aesthetically pleasing while protecting it from potential white rust or wet storage stains.
Why Choose Hot Dip Galvanizing?
Choose it for your steel products guarantees long-term protection and durability. The galvanizing process is performed according to internationally recognized standards, including ASTM A123/A123M, AS/NZS 4680, and BS EN ISO 1461, ensuring consistency and quality in every product. The result is a beautifully spangled, highly durable product that stands out not only in appearance but also in its ability to protect your investment from future maintenance costs.
