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: What are the dimensional inspection methods for steel strips?
- There are several dimensional inspection methods commonly used for steel strips. These methods are employed to ensure the accuracy and conformity of the dimensions of the steel strips to the specified standards. Some of the commonly used dimensional inspection methods for steel strips include: 1. Calipers: Calipers are used to measure the thickness, width, and length of the steel strips. They provide accurate measurements by directly comparing the dimensions of the steel strip with the calibrated scale on the caliper. 2. Micrometers: Micrometers are precision instruments used to measure the thickness and width of steel strips with high accuracy. They can measure dimensions up to the micrometer level, ensuring precise measurements. 3. Optical comparator: Optical comparators use magnification and illumination to compare the dimensions of the steel strip with a reference standard. This method enables visual inspection and measurement of various dimensions, such as width, length, and shape. 4. Laser measurement: Laser measurement systems utilize laser beams to measure the dimensions of steel strips accurately. They can provide non-contact measurements of width, thickness, and other dimensions, ensuring high precision and speed. 5. Coordinate measuring machine (CMM): CMM is a highly precise and automated dimensional inspection method. It uses a probe to measure multiple dimensions of the steel strip, including length, width, thickness, and even complex geometries. CMMs provide highly accurate measurements and are suitable for inspection of various steel strip profiles. 6. Vision systems: Vision systems use cameras and image processing algorithms to inspect the dimensions of steel strips. They can measure dimensions such as width, length, and thickness, and can also detect surface defects or irregularities. These dimensional inspection methods are often used in combination to obtain comprehensive and accurate measurements of steel strips. The selection of the appropriate method depends on the specific requirements, accuracy needed, and the type of steel strip being inspected.
- Q: How are steel strips inspected for internal defects?
- Steel strips are inspected for internal defects using various non-destructive testing methods. One common method is ultrasonic testing, where high-frequency sound waves are passed through the steel strip. If there are any internal defects such as cracks, voids, or inclusions, the sound waves will be reflected differently, and these reflections are detected by sensors. By analyzing the pattern of the reflections, the size, shape, and location of the internal defects can be determined. Another method used is magnetic particle inspection. In this technique, the steel strip is magnetized, and iron particles are applied on the surface. If there are any internal defects, the magnetic field within the strip will be disrupted, causing the iron particles to cluster around the defects. This clustering can be visually detected and indicates the presence of internal defects. Liquid penetrant testing is also employed to inspect steel strips for internal defects. In this process, a liquid dye penetrant is applied to the surface of the strip. The dye penetrates into any surface openings, such as cracks or voids, and is left to dwell for a specific period. After that, the excess dye is removed, and a developer is applied. The developer draws the remaining dye out of the defects, making them visible and easily detectable under proper lighting conditions. Additionally, eddy current testing can be used to inspect steel strips for internal defects. This method involves passing an alternating current through a coil, creating an electromagnetic field. As the coil is moved along the surface of the strip, any variations in the electromagnetic field caused by internal defects are detected by sensors. These variations are then analyzed to identify the presence and characteristics of internal defects. Overall, these non-destructive testing methods provide reliable and efficient ways to inspect steel strips for internal defects without causing any harm to the material. They play a crucial role in ensuring the quality and integrity of steel strips before they are used in various applications.
