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.
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.

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.
