Product Description:

Hot Dipped Galvanized Steel Coil

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications.

Application Of Hot Dipped Galvanized Steel Coil

It can be widely used in transportation, light industry, civil usage and farming. It is also the perfect building material in construction for making roofing tile, steel profiles for wall partition, T-bar, studs, fireproof door, air conditioning duct and home appliance.

Q: Are the steel sheets available in different thickness tolerances?: Yes, steel sheets are available in different thickness tolerances.

Q: What is the typical yield strength of steel sheets?: The yield strength of steel sheets can vary depending on the grade and type of steel used, with mild steel sheets commonly used in construction and manufacturing having a typical yield strength of around 250 megapascals (MPa) or 36,000 pounds per square inch (psi). Higher strength steels, like high-strength low-alloy (HSLA) steels or advanced high-strength steels (AHSS), can exhibit yield strengths ranging from 300 to 600 MPa (43,500 to 87,000 psi) or even higher. It is important to note that these values are general estimates and specific steel grades may possess slightly different yield strengths.

Q: Are the steel sheets recyclable?: Indeed, steel sheets possess recyclability. Owing to their remarkable recycling rate and convenient processing, steel stands as one of the extensively recycled materials worldwide. Upon reaching their lifespan's culmination, steel sheets undergo collection, sorting, and transportation to recycling facilities, where they undergo the melting process and are subsequently reshaped into fresh steel commodities. By recycling steel sheets, not only are natural resources conserved and energy consumption reduced, but waste is also diminished, thereby mitigating environmental consequences.

Q: Why is the water stop steel plate placed in the middle of the wall?: A water stop steel plate is an ordinary thin steel plate, not a waterproof coiled material, not a rubberized fabric, but imagine if a steel plate is placed on the outside of the concrete wall

Q: Can steel sheets be drilled or machined?: Yes, steel sheets can be drilled or machined.

Q: What is the difference between a HRPO and HRSPO steel sheet?: HRPO and HRSPO are both types of steel sheets, but they differ in their manufacturing process and resulting properties. HRPO stands for Hot Rolled Pickled and Oiled, while HRSPO stands for Hot Rolled Skin Passed and Oiled. The HRPO steel sheet is made by subjecting a hot rolled steel coil to a pickling process, which involves removing impurities and scale from the surface using an acid bath. After pickling, the steel sheet is then oiled to prevent corrosion during storage and transportation. This process results in a smooth and clean surface finish. On the other hand, the HRSPO steel sheet undergoes an additional skin pass process after pickling and oiling. During the skin pass process, the steel sheet is passed through a set of rolls to improve the surface finish and reduce its thickness. This process also imparts a certain level of cold work to the steel, enhancing its mechanical properties. In terms of properties, HRPO steel sheets exhibit good formability, weldability, and paintability due to their clean surface and lack of scale. They are commonly used in applications that require a smooth surface finish, such as appliances, automotive parts, and exposed architectural components. HRSPO steel sheets, with their improved surface finish and reduced thickness, offer even better formability and surface quality compared to HRPO sheets. They are often used in more demanding applications where precise dimensional control and surface aesthetics are crucial, such as automotive body panels, electrical enclosures, and furniture manufacturing. In summary, the main difference between HRPO and HRSPO steel sheets lies in the additional skin pass process that HRSPO undergoes, resulting in improved surface finish, reduced thickness, and enhanced mechanical properties. The choice between the two depends on the specific requirements of the application in terms of surface quality, dimensional control, and mechanical performance.

Q: What is the difference between a smooth and embossed steel sheet?: A smooth steel sheet refers to a sheet that has a flat and consistent surface without any texture or patterns. It is typically produced by rolling the steel through a series of rollers to achieve a smooth and uniform finish. Smooth steel sheets are commonly used in applications where a sleek and seamless appearance is desired, such as in architectural and interior design, automotive manufacturing, and appliances. On the other hand, an embossed steel sheet has a textured or patterned surface. This texture is created by pressing the steel sheet between embossing rollers, which impart a design onto the surface. The embossed pattern can be various shapes, such as diamonds, squares, or waves, and it adds a decorative and tactile element to the sheet. Embossed steel sheets are often utilized in industries like furniture manufacturing, signage, and decorative metalwork. In terms of functionality, smooth steel sheets are typically chosen for applications where a clean and unadorned surface is required, such as for painting, coating, or other surface treatments. They provide a blank canvas for further customization or finishing processes. In contrast, embossed steel sheets offer a visually appealing and distinct texture that can enhance the aesthetic appeal of a product or structure without the need for additional surface treatments. Additionally, the surface texture of a smooth steel sheet tends to be more resistant to fingerprints, smudges, and dirt accumulation compared to an embossed steel sheet. This makes smooth steel sheets easier to clean and maintain in applications where cleanliness is crucial, such as in food processing or healthcare industries. Overall, the main difference between a smooth and embossed steel sheet lies in their appearance, functionality, and suitability for specific applications. Whereas smooth steel sheets provide a clean, consistent, and versatile surface, embossed steel sheets offer a decorative and textured finish that can enhance the visual appeal of a product or structure.

Q: What is the typical fatigue strength of a steel sheet?: The typical fatigue strength of a steel sheet can vary depending on factors such as material composition, thickness, surface condition, and loading conditions. However, for most common steel sheets, the fatigue strength usually falls within the range of 30 to 70 percent of the ultimate tensile strength of the material.

Q: Are the steel sheets susceptible to rusting?: Yes, steel sheets are susceptible to rusting as steel is prone to corrosion when exposed to moisture and oxygen.

Q: Can steel sheets be used for manufacturing storage tanks?: Yes, steel sheets can be used for manufacturing storage tanks. Steel is a commonly used material in tank fabrication due to its strength, durability, and resistance to corrosion. It can be easily formed into sheets and welded together to create storage tanks of various sizes and shapes.
