Is there a standard diameter for bumper plates?
The standard diameter of a bumper plate is 450mm (17.7165 inches). This is the same diameter as competition-style iron plates, ensuring consistency in the barbell height.

How are bumper plates different from traditional iron plates?Bumper plates are made of rubber, which allows them to be dropped safely without causing damage. Traditional iron plates are not designed for dropping and can damage both the floor and the plates if dropped.

What is SBR NR Rubber found in your bumpers?
SBR NR rubber is known for its excellent durability and resilience, making it well-suited for absorbing impact and withstanding repeated use, which is crucial for bumper plates in weightlifting environments. SBR rubber also has good shock absorption properties, helping to reduce noise and vibration when weights are dropped onto the plates.

What are bumper plates used for?
Bumper plates are commonly used in Olympic weightlifting and cross training. They are ideal for movements where the barbell is dropped, such as clean and jerk or snatch, as they protect the barbell and the lifting platform.

What is the difference between bumper plates and traditional rubber coated plates?
Bumper plates are made from a dense rubber and are specifically designed for Olympic weightlifting movements where the barbell is dropped. Rubber coated plates are not designed for dropping. Another difference you’ll find is bumper plates all have the same diameter. The diameter of a rubber coated weight plate will generally decrease as the weight decreases.
