Established in 1982, Stone Industrial Co., Ltd. is a leading supplier of metal products from China.
In the humble beginning, we involved ourselves in the fields of casting, forging, stamping, and precision turning. From such beginning, we got rich experiences on metal processing and are still benefiting from the knowledge gained ever since. Although always taking care of Customized parts by various forming processes, we have been focusing on valves and fittings for 8 years. Made in the materials of brass, bronze and stainless steel, the products are widely used in the systems of water distribution, heating and air-conditioning.
Through years of continuous trying, we have formed a strong production network containing more than 10 factories, covering investment casting of lost wax process for stainless steel fittings, sand casting for brass and bronze fittings, hot forging for brass fittings and other forming processes. At the same time, the products from us are well recognized in USA, Germany, UK, Ireland, Denmark, Australia and other lands for the competitive prices, in-time delivery and considerate services.
