The Body Builder Barbell Plates are ideal for commercial gyms and or college/pro gyms. The Hard rubber coating will not chip or peel as a result of normal use. These plates are very thin and great for stacking heavy loads on a barbell or plate loaded machine. The rubber coating absorbs any noise and keeps the plates fitting together tightly. High quality rubber offer very minimal odour unlike lower costing options. The stainless-steel insert will not depart from the plate and allows the plates to side on and off bars and machines easily.
