The 4 feet Olympic Curl Bar is constructed from high-quality steel, ensuring superior strength, toughness, and welding performance, along with enhanced corrosion resistance to prevent rusting. The sleeve surface undergoes electroplating treatment, resulting in a smooth and visually appealing finish. The double knurling design on the grip enhances friction between the hand and the bar, improving grip stability. Additionally, the bending bar design helps alleviate wrist pressure and reduces the risk of injury during triceps exercises.SPECIFICATIONS Color silver Material steel Weight 10KG Length 120cm (tolerance + / ÃÂñ 0.5mm) Load capacity 500LB Tensile strength 110k PSI Grip diameter 28mm Grip surface treatment electroplating Knurling Double knurling 1.2mm Sleeve diameter 50mm Sleeve Length 17cm Sleeve surface treatment electroplating Bearing roller pin 2, and copper sleeve 2
