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.

With stop discs, you can practice in complete safety!
Don't forget to invest in a pair of disc stops to prevent your weights from slipping off the bar during your workout. Ours are sold in pairs (ref: 8574652).
The maximum weight supported by the stop discs in the vertical position is 15kg.
Store your disks properly for long use
Store your discs indoors in a dry place.
By investing in a disc holder (ref: 8796727) or a storage rack (ref: 8788246), you'll save floor space.
A cabinet base can also be used to store your bodybuilding weights.
Don't hesitate to clean them with a microfiber cloth if they've gathered dust.
