USA Made Urethane Barbell Sets by Iron Grip are the preferred fixed weight urethane barbell sets of clubs and the US military. Each fixed weight barbell is constructed from precision-machined steel bars that are knurled with a medium diamond knurl for ultimate comfort and maximum grip. The bars are then coated with a chip-resistant hard chrome finish that holds up well even through years of re-racking on barbell racks. The solid steel heads are welded to each bar to create a totally maintenance free barbell. Iron Grip’s proprietary urethane composition and manufacturing process insures maximum durability and adhesion to each solid steel core. Need an Iron Grip barbell quote? Contact IRON COMPANY today.
