In a recent feedback survey conducted by my gym, I indicated that the gym needed to replace a few of their bars, and/or buy new ones. To my surprise, the gym manager contacted me directly and asked me for specific recommendations. I've never bought gym equipment before; what are some good quality brands of bars? They are looking specifically for regular olympic bars and curls bars (both the regular 15 lb. variety and the longer, thicker 35 lb. ones if possible).
