Why choose cast iron instead of plastic or vinyl bumper weights?
- Cast iron is a dense material that is more compact than vinyl, which means you can add more discs to the bar (up to 32 kg on one dumbbell bar)
- Cast iron lasts a lifetime, unlike plastic or vinyl, which can wear out within a year.
- Cast iron is less affected by temperature changes so you can use it in a range of conditions.
Our cast iron plates are made from at least 80% recycled cast iron
Since 2018, our teams have been gradually integrating recycled materials until we reached the perfect balance. Following several years of experiments, Decathlon is replacing its entire range of cast iron products with recycled cast iron made from at least 80% scrap metal and steel waste – a real feat for the world of metal! To ensure that the quality is the same as classic cast iron, tests are carried out in partner laboratories.
Why should you use cast iron weights?
- Cast iron better withstands shocks, drops and crushing (5 times better) than vinyl.
- Cast iron has a textured surface for excellent grip even when your hands are damp, unlike plastic, which can be slippery.
Choosing our cast iron weights means you can work out confidently and efficiently.

Don't forget disc collars for training safely
Remember to invest in a pair of disc collars to lock the weights on your bar as you exercise. Our Smart Disc Collars are sold in pairs (ref: 8574652) so that you can train safely.
Just be careful: their weight limit in a vertical position is 15 kg.
Our advice for storing your cast iron weight training discs!
- To store your cast iron plates, you can use a wall mount for discs (ref: 8796727) or a storage rack (ref: 8788246) to install indoors (such as in a garage).
- Do not store your weights outdoors or in a damp place, since cast iron risks rusting if exposed to moisture.
- Dust your discs with a microfibre cloth when they have been stored for a long time.
