Hot Dipped Galvanized Steel Coil/Hot Dipped Galvanized Steel Strips Coil/Zinc Coated Steel Coil Description:
Galvanized steel coil are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 – 180 grams per square metre.
Main Features of Hot Dipped Galvanized Steel Coil/Hot Dipped Galvanized Steel Strips Coil/Zinc Coated Steel Coil:
Hot-dip galvanized steel coils are produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel. After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460 ° C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customer’s demand.

- Q: How are steel strips processed for galvanizing?
- Steel strips are processed for galvanizing through a series of steps to ensure proper adhesion and corrosion resistance of the galvanized coating. The process typically involves the following steps: 1. Surface Preparation: The steel strips are first cleaned through various methods to remove any dirt, oil, or rust present on the surface. This can be done through chemical cleaning, mechanical cleaning (such as shot blasting), or a combination of both. 2. Pickling: After surface preparation, the steel strips are immersed in a pickling solution, usually a diluted acid, to remove any remaining scale or oxides. This step helps to create a clean and chemically reactive surface for the galvanized coating to adhere to. 3. Fluxing: Once the pickling process is complete, the steel strips are rinsed to remove any residual acid and then immersed in a flux solution. The flux solution helps to prevent oxidation of the steel surface prior to galvanizing and promotes the formation of a uniform and smooth zinc coating. 4. Galvanizing: The steel strips are then passed through a bath of molten zinc at a high temperature. The zinc reacts with the steel surface to form a metallurgical bond, creating a protective zinc coating. The thickness of the coating can be controlled by controlling the speed at which the steel strips pass through the zinc bath. 5. Cooling and Quenching: Once the steel strips are galvanized, they are cooled to solidify the zinc coating. This can be done through air cooling or by quenching the strips in water. The cooling process helps to ensure the integrity and durability of the galvanized coating. 6. Inspection and Quality Control: After cooling, the galvanized steel strips are inspected for any defects or inconsistencies in the coating. This can include visual inspection, measurement of coating thickness, adhesion tests, and other quality control measures. Any defects found may require corrective actions or rework before the steel strips can be considered ready for further processing or use. Overall, the process of galvanizing steel strips involves a combination of surface preparation, chemical reactions, and quality control measures to provide a durable and corrosion-resistant coating. This coating not only enhances the longevity of the steel but also provides an aesthetically pleasing finish for various applications in industries such as construction, automotive, and manufacturing.
- Q: How are steel strips used in the manufacturing of aerospace turbines?
- Steel strips are used in the manufacturing of aerospace turbines as they are formed into precise shapes and sizes to create various components such as blades, casings, and shafts. These strips provide the necessary strength, durability, and heat resistance required for the demanding conditions in aerospace turbines, ensuring optimal performance and safety of the turbine system.
- Q: What are the different welding methods used for steel strips?
- There are several different welding methods that can be used for steel strips, depending on the specific application and requirements. Some of the most common welding methods used for steel strips include: 1. TIG Welding (Gas Tungsten Arc Welding): This method uses a non-consumable tungsten electrode to create the weld. It provides excellent control and precision, making it suitable for thin steel strips and applications that require high-quality welds. 2. MIG Welding (Gas Metal Arc Welding): This method uses a consumable wire electrode and an inert gas shield to protect the weld from atmospheric contamination. MIG welding is fast and efficient, making it suitable for high-volume production of steel strips. 3. Laser Welding: This method uses a high-energy laser beam to melt and join the steel strips. Laser welding offers high precision and speed, making it suitable for thin steel strips and applications that require minimal heat input. 4. Spot Welding: This method uses electrical resistance to join the steel strips by creating a series of overlapping spot welds. Spot welding is commonly used for joining steel strips in the automotive industry. 5. Seam Welding: This method is similar to spot welding but creates a continuous, leak-proof weld along the entire length of the steel strip. Seam welding is often used for joining steel strips in the production of pipes, tubes, and tanks. 6. Flux-Cored Arc Welding: This method uses a tubular electrode filled with flux to join the steel strips. It offers high deposition rates and deep penetration, making it suitable for thicker steel strips and applications that require high weld strength. 7. Submerged Arc Welding: This method uses a granular flux and a continuously fed bare electrode to create the weld. Submerged arc welding is commonly used for welding thicker steel strips and for applications that require high productivity. Each welding method has its advantages and limitations, and the choice of method will depend on factors such as the thickness of the steel strips, the desired weld quality, the production volume, and the specific application requirements.

- Steel strips can be used in corrosive environments, but it is important to select the appropriate type of steel with corrosion-resistant properties. Stainless steel strips, for example, are specifically designed to withstand corrosion and are commonly used in such environments.
- Q: What are the storage guidelines for steel strips?
- To ensure the longevity and prevent damage of steel strips, it is important to adhere to storage guidelines. Firstly, it is crucial to store them in a dry and well-ventilated area to avoid the accumulation of moisture which can lead to corrosion. Direct exposure to sunlight should be avoided as it can cause discoloration and degradation of the steel's surface. Furthermore, steel strips should be stored horizontally, either stacked or on racks, to prevent bending or warping. It is advisable to place wooden or rubber spacers between layers to provide support and prevent contact between the strips which may cause scratching or other surface damage. When stacking the strips, it is necessary to evenly distribute the weight to avoid excessive pressure on the lower strips. Additionally, they should be kept away from chemicals or substances that may stain or react with the steel. Regular inspections should be carried out to identify any rust or damage. If any issues are found, appropriate measures such as cleaning, applying rust inhibitors, or seeking professional assistance should be taken. By following these storage guidelines, steel strips can be preserved in optimal condition, ensuring their quality and performance in various applications.
- Q: What are the common standards for steel strips?
- The common standards for steel strips include specifications such as ASTM A109/A109M, EN 10139, JIS G3141, and DIN 1624. These standards define the chemical composition, mechanical properties, dimensions, and tolerances for steel strips used in various industries like automotive, construction, and manufacturing.
