Whether you are a seasoned professional or just starting out, understanding the best practices for handling and storing coiled aluminum strip is essential to maintaining its quality and usability while contributing to a safer work environment. In this guide, we will detail techniques to help you effectively manage your coiled aluminum strip inventory, from initial handling to long-term storage.
Proper Handling
When working with coiled aluminum strip, proper handling is critical. From the time the strip arrives at the facility to the time it is used, each handling step affects the quality of the strip. Essentially, it all comes down to the old saying: "Handle with care." Here are the specific actions and precautions you should take to minimize damage to your materials:
1. Inspect received materials for any damage or moisture. If any damage or moisture is found, note it on the shipper's documentation and notify your supplier as soon as possible.
2. Only store aluminum where humidity and temperature will not cause condensation. A heated, humidity-controlled environment is best.
3. Metal that is below the temperature of the location must be allowed to warm up to ambient temperature.
4.Handling of coiled strip may vary depending on orientation as follows:
- For vertical coils/eye-to-sky coils, ensure it is securely tied before moving or lifting. This type of coil is typically lifted by a crane or forklift with a C-hook. Ensure the coil weight or size does not exceed the equipment limitations. Do not place coils directly on a concrete floor, use some kind of coil pad or mat under the coil. Secure the coil with a chuck or bracket to prevent rolling. Stacking coils on top of each other is not recommended. Always follow all applicable safety precautions.
- For eye-to-sky coils on a skid, it is typically moved using a forklift. Again, ensure the equipment used is capable of safely transporting the size and weight of the package. Pay attention to the center of the load. Never attempt to lift a coil mounted on a damaged skid. Be careful to avoid fork contact with metal as this may cause sidewall damage. Individual cutouts or coils on a skid may be lifted with a sling, vacuum grab, or other equipment. Always follow all applicable safety precautions.
5.Before processing aluminum, the processing equipment should be inspected for cleanliness. All contact surfaces and rollers should be thoroughly cleaned and inspected for damage to prevent defects from being transferred to the strip.
Proper Storage
Proper storage is key to maintaining the quality of coiled aluminum strip over the long term. Improper storage conditions can lead to corrosion, deformation, and other forms of damage that can affect the usability and performance of the material. Here are some best practices for storing coiled aluminum strip to help optimize its life and performance:
1. If possible, keep coiled strips in their original packaging until needed.
2. If coils are stored side by side, make sure they are re-tied tightly before moving to ensure security and prevent scratches caused by the winding shifting.
3. To minimize the possibility of water stains, the storage location should be heated and humidity controlled. Differences in metal temperature and storage location can cause condensation and water stains. Condensation forms if the metal temperature is below the dew point of the surrounding air. Storing aluminum in places with temperature changes (such as near an exterior door) or exposed to high humidity increases the likelihood of damage. Water stains
Or "white rust" is when moisture is trapped between coils and the absence of any airflow causes a chemical reaction on the surface, which is a form of corrosion. This water corrosion begins to occur immediately when aluminum is exposed to moisture and cannot be removed.
4. Industrial storage racking systems can help eliminate the need to stack slip coils directly on top of each other and reduce the likelihood of edge damage.
Proper handling and storage are important aspects of effectively managing your coiled aluminum strip inventory. By following the guidelines we've outlined here, you can minimize the risk of damage and ensure the longevity and performance of your coiled aluminum. Remember to handle with care, protect the material, store in proper conditions, and inspect regularly for signs of damage. With these practices, you can get the best results from your coiled aluminum strip.
