Vulcan Bumper Plates are built to endure the rigors of Olympic Weightlifting and CrossFit® workouts. Unlike lower priced brands, our Bumper Plates are made of a harder and denser rubber compound. As a result, our Bumper Plates have a much thinner profile and more plates can be fit on the bar.

Others claim to have equivalent rubber hardness, but their 10 lb and 15 lb bumper plates "waffle" easily when dropped. They offer minimal or no posted warranty on their bumper plates. They state that their plates are not made for dropping. Vulcan Bumper Plates Are Made To Be Dropped!

The typical Bumper Plate has a thin pressed steel insert which will come out over time with repeated droppings. Our inserts are forged solid steel and anchored into the plate. We were the first to introduce this technology in 2011 and to this day we have replaced less than two dozen bumper plates out of thousands of tons of plates sold.

One of the things you will immediately notice when lifting our bumper plates is how snugly they fit together on the bar as well as the dead blow/low bounce effect they exhibit when dropped. It's a very noticeable sound compared to the clanking rattling noise and basketball-like rebounding you will experience with lesser brands.

Be aware that low cost bumper plates are made from low cost materials.

They are made with recycled materials and use chemicals in processing that contain PAHS. Inferior methods of processing produce low grade rubber with high levels of surface defects and high odor. Vulcan bumper plates are PAHS free and made from first use natural virgin rubber.
