HDGI COIL / ALU-ZINC COIL Factory

Production process of HDGI steel coils

First, the steel base material selected during the production process is crucial. Usually, hot-dip galvanized steel coils use hot-rolled steel coils or cold-rolled steel coils that have been carefully selected for good formability and strength. After cleaning and pretreatment, the steel coils are sent to the galvanizing tank. The zinc liquid in the galvanizing tank is heated to about 450°C, causing the surface of the steel base material to react chemically with the zinc quickly to form a uniform zinc coating. The thickness and quality of the zinc coating directly affect the corrosion resistance of the product, so this process requires highly precise control to ensure the uniformity and adhesion of the zinc coating.

After the galvanizing process is completed, the steel coil enters the cooling zone, where it gradually cools to room temperature to ensure a good bond between the coating and the substrate. The cooling process not only helps harden the zinc layer, but also affects the surface quality of the steel coil. In order to further improve the corrosion resistance of the steel coil, the galvanized steel coil is sometimes surface treated, such as applying a thin layer of aluminum-zinc alloy or other anti-corrosion coating. These additional layers can further improve the performance of the steel coil, especially when used in humid or extreme environments, which can effectively prevent rust.

For manufacturers, precise process control and high-quality raw materials are the key to ensure the superior performance of hot-dip galvanized steel coils. The HDGI steel coils produced by our company have strict standards in quality control, using high-quality hot-rolled steel substrates and advanced galvanizing technology to ensure that each coil of steel meets ISO9001 certification standards.

How to maintain and maintain alu-zinc coils

Firstly, maintaining the cleanliness of the surface is crucial. Over time, dust, dirt, or chemicals may accumulate on the alu-zinc coil's surface, which could potentially cause corrosion of the coating. To prevent this, it is important to regularly clean the surface with a mild cleaner and a soft cloth to remove contaminants and prevent them from penetrating the coating. It is important to avoid using strong acids or alkalis, as these chemicals can damage the aluminum-zinc coating and reduce its corrosion resistance. Additionally, the storage environment of the alu-zinc coils is important. They should not be stored in damp or chemically hazardous environments to avoid oxidation of the coating.

For alu-zinc coils exposed to extreme environments, especially in coastal or industrial areas, their surface may be subject to more corrosion pressure. Regularly checking the coating for any damage or peeling and promptly repairing or re-coating the surface is an effective way to extend the service life of the coils. In some cases, minor scratches or abrasions may appear on the surface of the alu-zinc coils. In such cases, specialized repair materials can be used to fill these damages and prevent further corrosion from spreading.

In addition to surface cleaning and repairs, proper storage is also a key factor in maintaining alu-zinc coils. During storage, alu-zinc coils should be kept away from moisture or corrosive substances. They should be stored in a dry and well-ventilated warehouse. If the coils need to be stored for an extended period, they should be wrapped in moisture-proof paper or plastic film to prevent direct contact with moisture in the air.

Our alu-zinc coils are manufactured using advanced production processes and high-quality raw materials, ensuring that each coil has outstanding corrosion resistance and strength. Through strict quality control and detailed surface treatments, our alu-zinc coils perform excellently in the market and are widely used in industries requiring durable and high-strength materials. To maintain the best performance of our products, we recommend that customers follow the maintenance and care guidelines mentioned above. This will not only extend the life of the alu-zinc coils but also ensure that they continue to provide excellent corrosion protection in various environments.
