The weight plate is made of solid rubber, which a real Bumper plate should be, and therefore adheres to the hard drops that occur in both functional training and deadlift. Bumper plates of 5, 10, 15, 20 and 25 kg. all have a diameter of 45 cm., and have a metal ring in the middle, which both makes the discs slide easier on the lever and gives extra durability. There are clearly kg. indication on the weight plate.
Note that there are some Bumper plates on the market that are not solid rubber, but instead rubber coated cast iron discs. In heavy use, the cast iron plate may break in these, after which the stability will disappear and the Bumper plate will subsequently not be usable.
