Packaging

Efficient Coil Handling

LWC coils are wound in an “eye-to-the-sky” format, optimizing loading efficiency and minimizing handling costs on production lines. Coils are mounted on bobbins and placed on wooden or chipboard pallets based on customer preference. The ends are capped, and nitrogen purging protects the inner surface from oxidation and contamination.
