Galvanizing technology

About Galvanizing

Steel is used in various fields and is among the most popular materials with a wide range of applications. Its surface requires special care due to its tendency to react with the natural environment and corrode. The galvanizing process allows a steel part to acquire a protective layer. This is sufficient for several decades of use without the risk of rust.

For this purpose, pre-treated steel parts are immersed in a hot zinc bath at a temperature of approximately 450°C as part of a multi-stage immersion method. An anti-corrosion protective coating is formed on the surface in the form of a zinc-iron alloy layer. The component is protected and requires no maintenance. This technique is also environmentally friendly.

Hot-dip galvanizing

Galvanizing is one of the most popular methods for protecting metal components that are prone to rusting. To achieve this, a layer of zinc is precisely applied to a degreased surface that is free of any impurities or traces of rust. We distinguish several types of this process – including electro-galvanizing, hot-dip (immersion) galvanizing, thermal spraying, or powder coating. Various types of steel structures, for example, are subjected to this form of protection, which extends their durability and resistance to any damage, abrasion, or corrosion.

Spin galvanizing

Low-temperature galvanizing is a technology that protects safety-critical components operating under heavy loads. This method provides long-lasting corrosion protection and requires no maintenance, unlike paint coatings. It is also characterized by higher resistance to mechanical damage compared to electro-galvanized coatings.

Due to the launch of an automated production line and the installation of a galvanizing centrifuge, issues such as zinc runs (excess zinc) have been eliminated. This allows for consistent coating repeatability and the ability to galvanize small components such as washers, chains, clamps, anchors, etc. Additionally, the parts do not require further processing, which significantly shortens the galvanizing process and allows them to be used immediately upon completion. This method is considered one of the best anti-corrosion protections, and its execution in accordance with the PN-EN ISO 1461 standard guarantees a coating of the highest quality.
