Barbell Plate Series — Wholesale OEM Manufacturer | ShuangJia Sports

ShuangJia Sports is a China-based barbell plate manufacturer with over 20 years of manufacturing experience. Our ISO 9001 certified factory in Shandong produces a complete range of weight plates: color bumper plates, black bumper plates, precision steel plates, CPU plates, TPU hand-grip plates, and Olympic casting plates.

We control the entire production process in-house — from iron casting and rubber vulcanization to precision machining and final assembly. Every plate is tested for durometer hardness, weight tolerance, and bounce consistency before leaving the factory.

OEM is our standard. Customize plate color, logo placement, collar insert material (steel or stainless steel), and packaging to match your brand. Whether you're building a commercial gym line or launching your own fitness brand, we deliver factory-direct quality at competitive wholesale pricing.
