The barbell is made of high quality materials with a special quenching process. Made with 40Cr alloy steel material, the tensile strength is 160k. After a specific heat treatment process, the properties of the material, elasticity, and fatigue strength are improved. The fatigue strength is better and the barbell will not bend after long-term use.The length of the bar is 2.01m, 25mm diameter handle, and a weight of 15kg. The weight and size of each rod are accurately calculated and cut with a weight tolerance of +/- 1%. Steel could deform under a combination of thermal stress and structural stress. We will straighten deformed barbells.
