What Are One Of The Best Barbell Plates To Use For Olympic Style Lifting? Solid Rubber Bumper Plates! Why? Because they bounce when dropped and provide a cushion to the floor underneath and the bar you are using. Using cast iron Olympic plates during snatching and cleaning would not only ruin your floors but your equipment, as well. Ironcompany® has the largest online selection of bumper plate sets which includes black, colored, crumb rubber, virgin rubber, recycled rubber, cast iron core and urethane.
