Durable, Classic Design: Premium Cast Iron Adjustable Dumbbells for Your Business.

The Cast Iron Adjustable Dumbbells are meticulously crafted using a casting process that ensures each weight plate is formed in a single mold. This method guarantees durability and precision. After casting, the plates undergo a grinding and polishing process, followed by a spraying treatment, which provides a protective layer, ensuring longevity and resistance to wear and tear.
