Why choose a cast-iron weight rather than a plastic or vinyl one?
- Thanks to its density, cast iron is more compact than vinyl, which means you can increase the number of discs on the bar (up to 32 kg on a dumbbell)
- Cast iron can be kept for life, unlike plastic or vinyl, which can last less than 1 year.
- Less affected by temperature variations, cast iron offers constant use in different climatic conditions.
Why use cast-iron weights?
- Cast iron is 5 times more resistant to impacts, falls and crushing than vinyl.
- Cast iron has a textured surface for excellent grip, even with wet hands, unlike plastic, which is often slippery.
Choosing our cast iron weights means opting for efficiency and reliability in your training.

Our tips for storing your cast-iron bodybuilding discs!
- To store your cast-iron weights, you can use a wall-mounted disc holder (ref: 8796727) or a storage rack (ref: 8788246) to be installed indoors (garage, for example).
- Avoid storing your weights outdoors or in damp locations, as cast-iron can rust if exposed to moisture.
- Dust your discs with a microfiber cloth when they have been stored for a long time.
