Why choose a cast iron weight rather than a plastic or vinyl one?
- Due to its density, cast iron is more compact than vinyl, allowing you to 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.

Add disc collars for your safety
To train safely, your weight training plates need to stay in place as you exercise. That's where the disc collar comes in! This little accessory locks the weights onto your bar or dumbbell.
Our Smart Disc Collars are sold in pairs (ref: 8574652). Note that their weight limit in a vertical position is 15 kg.
Proper storage of cast iron weight training discs
Humidity is the enemy of your weight training plates!
That's why it's important not to store them outdoors or in a basement.
Here are a few tips to help your weights last longer:
- Store them in a dry place
- Dust them when needed with a microfibre cloth
- Store them on a wall mount for discs (ref: 8796727), on the bottom of a piece of furniture, or on your storage rack (ref: 8788246)
Our coach's tip for using your weight training plates
Load your dumbbell with two 2 kg cast iron weights and start a set.
Shoulder exercise:
- Military press with dumbbells 3×10 reps
Keep a 2 rep margin at the end of each set.
Add reps as the weeks progress, then add weight, and start again with just 10 reps.
The advantage of these weights is that they allow you to adjust the load based on your needs and the muscle groups you're working.
Tips for storage and maintenance
Do not wash
Do not bleach
Do not tumble dry

Storage tips
Store them in a dry place. They are sensitive to moisture and may rust.
You should also dust them once in a while using a dry or damp microfibre cloth.
