USA Made Iron Grip Olympic Weight Plates. Are all weight plates created equally? Absolutely not! We’ve just about seen it all when it comes to cheaply made imported plates. From actual plate weights that can be plus or minus several pounds to giant air pockets in the castings filled with putty or even rocks that have been thrown into the molten iron mix as filler. You definitely get what you pay for when it comes to high quality American Made Olympic plates. Each plate is cast from the highest quality iron and any seems are ground smooth and then painted. Accuracy is within +/- 2%. The USA Made urethane coated plates hold the same high standards and are coated with a thick and resilient urethane coating that is highly impact resistant and won’t tear up your floors or other equipment. American Made Iron Grip Weightlifting Plates are the equipment of choice among most military bases and club chains because they last!
