Staff are trained and s0009ed by strict overseas technology . The quality of products is consistent and the specifications are complete. The annual output of diameter DIA 20MM-DIA 150MM grinding steel ball is 100000 tons. Due to the application of internationally advanced technology and manufacture experience ,our grindingsteel balls have the advantages of rubbing endurance, crashing tolerance and roundness persistence ,compared to other products in this field. We record the data for our products, follow up customers and drop in services at calling to solve customers' uncertainties.  ------------------------------------Quality assurance------------------------------------------- 1.We only purchase directly from large regular steel groups in China.  2.10 advanced automatic production lines with an annual output of 100,000t. Covering the specifications of DIA15-150 mm and all materials to meet customers' different requirements. All of the operators are well trained and have more than 5 years of experience in forging ball manufacturing. 3.We adopt unique complex heat treatment craft. By repeated quenching, the quenching liquid temperature control, the continuous tempering, etc., the steel ball has better performance in the volume hardness uniformity and the overall wear resistance. 4.World-class laboratory and complete test equipment enable us to make tests of chemical elements, mechanical properties, microstructure and so on.  5.We have passed international and industrial certifications such as TUV ISO900, ISO14001, Iso45001, etc and also passed the double certification of SGS and BV as qualified factories. ​ ------------------------------------Packing & Delivery------------------------------------- 1. Ocean shipping 2. Customers designated transportation mode.  3. Packing Details: A. Steel drums (850-930kgs/drum) b. Flexible container bags(1ton/bag) 4. Delivery Details: Within 15-20 days after received the payment or LC at sight.
