Design details
Dimensions of the 20 kg weight
20 kg cast iron weight with rubber coating:
- Thickness: 45 mm
- Interior diameter: 28 mm
- External diameter: 394 mm
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.
What are these rubber-coated weights for?
These weights can be used on 28 mm bars or without a bar using their ergonomic handle.
Their rubber coating dampens impacts and keeps them from marking your floors.

Disc collars are essential with your weights
If you plan to use your weights on bars or dumbbells, you'll need disc collars (ref: 8574652). They are sold as a pair! Note that they can support up to 15 kg of weight in a vertical position.
How to store your weights to keep them for a long time
These weight training discs are made of cast iron, covered in rubber. Cast iron can rust if exposed to the elements or to moisture, which is why we recommend storing these weights indoors in a dry place.
If you want to clean your weights, you can use a damp or microfibre cloth.
And for storage, you can use a specially-designed mount (ref: 8796727) or the bottom shelf of a piece of furniture.
