    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.
    The stainless steel collar makes them easy to install on bars.

    What bar can you use this weight with?

    This rubber weight is compatible with 28 mm diameter bars:
    - 1.2 metre straight bar (ref: 8289897)
    - 1.2 metre curl bar (ref.: 8484124)
    - 86 cm triceps bar (ref.: 8484125)
    - 35 cm short bar (ref.: 1041986)

    - 2 m straight bar (ref.: 8289900)

    It is not compatible with weight-lifting bars (with a diameter of 50 mm).

    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.

    From extraction to production, metal has a high environmental footprint. To help reduce it, we use recycled metal in this product — sourced from recovered scrap, sorted, shredded, and melted down in electric furnaces, which are far less energy-intensive than traditional coal-fired blast furnaces. The result: the same performance as virgin metal, with a lower environmental impact: – 40% less energy used – 19% fewer CO2eq emissions – and fewer raw materials extracted
