Galvanized Steel Coil/Hot Dipped Galvanized Steel Strips 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 Galvanized Steel Coil/Hot Dipped Galvanized Steel Strips Coil：
Hotdip 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.

FAQ:
Q: Are you manufacturer of trading company?
A: Yes.
- Q: How do steel strips perform in extreme temperature conditions?
- Steel strips generally perform well in extreme temperature conditions. Steel has a high melting point and retains its strength and durability even at very high temperatures. In extremely cold temperatures, steel strips may become more brittle, but they still retain their structural integrity. Overall, steel strips are known for their excellent performance in extreme temperature conditions.
- Q: Can steel strips be used in the production of springs or fasteners?
- Yes, steel strips can be used in the production of springs or fasteners. Steel strips provide the necessary strength, durability, and flexibility required for these applications. They can be formed, bent, and shaped to create springs or fasteners with varying sizes and configurations.
- Q: How are steel strips processed for improved surface finish?
- Achieving an improved surface finish for steel strips can be accomplished by employing various methods. One commonly used technique involves pickling and oiling. In this process, steel strips are submerged in an acidic bath, typically hydrochloric acid, to eliminate any scales or impurities present on the surface. This step ensures the creation of a smooth and clean surface. Following pickling, the strips are thoroughly rinsed and then coated with oil to prevent oxidation and enhance the overall appearance. Another approach to enhancing the surface finish of steel strips is through cold rolling. This method entails passing the strips through a series of rollers at room temperature. Not only does this process reduce the thickness of the strips, but it also improves the surface finish. Cold rolling plays a crucial role in producing a uniform and smooth surface, effectively minimizing imperfections and roughness. Furthermore, annealing can be employed as a means of improving the surface finish of steel strips. Annealing is a heat treatment process that involves heating the strips to a specific temperature and gradually cooling them. This technique effectively relieves internal stresses and enhances the crystal structure of the steel, ultimately resulting in a refined and smoother surface. Moreover, mechanical treatments like grinding or polishing can further enhance the surface finish of steel strips. Grinding employs abrasive wheels or belts to eliminate imperfections and roughness from the surface. On the other hand, polishing utilizes a fine abrasive material to create a smooth and glossy surface. To summarize, various methods such as pickling and oiling, cold rolling, annealing, and mechanical treatments like grinding and polishing can be employed to achieve an improved surface finish for steel strips. These processes effectively eliminate impurities, reduce roughness, and result in a clean and smooth surface, enhancing both the appearance and performance of the steel strips.
- Q: How are steel strips tested for tensile strength?
- Tensile testing is the method used to test the tensile strength of steel strips. This method involves applying a force to the strip until it breaks, while measuring the force required for the break. Typically, this testing is done using a specialized machine called a tensile testing machine. To conduct the test, a sample of the steel strip is prepared in a specific shape and size, usually in the form of a dog bone-shaped specimen. The specimen is then securely clamped into the grips of the tensile testing machine. One grip is attached to the upper part of the machine, while the other grip is attached to the lower part. Once the specimen is in place, the machine gradually applies an increasing force in the opposite direction of the clamps. This force causes the steel strip to stretch and elongate until it eventually fractures. Throughout this process, the machine records the applied force and the corresponding elongation of the strip. The recorded data is then plotted on a stress-strain curve, which illustrates the relationship between the applied force (stress) and the resulting deformation (strain) of the steel strip. By identifying the maximum force the strip can withstand before breaking, the tensile strength of the strip can be determined. Tensile testing provides valuable information about the mechanical properties of the steel strip, including its ultimate tensile strength, yield strength, and elongation. These properties are crucial in determining the suitability and quality of the steel strip for specific applications in industries such as construction and manufacturing.
- Q: How are steel strips used in the manufacturing of marine equipment?

Each coating option provides specific benefits such as corrosion resistance, improved durability, and enhanced aesthetics. The choice of coating depends on the intended application and the desired properties of the steel strips.
- Q: What are the main factors affecting the corrosion resistance of steel strips in different environments?
- The main factors affecting the corrosion resistance of steel strips in different environments include the composition of the steel, the presence of corrosive substances or agents in the environment, humidity, temperature, and the duration of exposure to the corrosive environment. Additionally, the surface condition of the steel, such as the presence of surface coatings or protective layers, can also influence its corrosion resistance.
- Q: What are the common dimensions for steel strips?
- The common dimensions for steel strips vary depending on their intended use and industry standards. However, some commonly available dimensions for steel strips include widths ranging from 0.5 inches to 24 inches, and thicknesses ranging from 0.005 inches to 0.5 inches.
- Q: How are steel strips used in the chemical industry?
