The Hammer Strength Hex Bar is made with welded-steel and powder-coated. The grip diameter is standard at 1.31” diameter.
Great quality. Knurling is perfect as is the quality of the finish. Purchased a Rogue multi-grip bar and the knurling is too abrasive and the finish is of lesser quality. Would have bought the Life Fitness multi-grip bar if the inner handles weren’t angled. Hopefully Hammer Strength offers a variety of multi-grip bars in the future. I will be reselling my Rogue when that day comes and I will be buying Hammer Strength. I highly recommend the Hammer Strength hex bar.
