Shougang Guiyang Special Steel Co., Ltd. (referred to as Shougang Guigang Company), formerly known as Guiyang Special Steel Co., Ltd. and Guiyang Steel Plant (referred to as Guigang), was founded in 1958. It is a national key metallurgical enterprise and an important special steel enterprise in the west. The country's largest scientific research and production base of drill steel products for rock drilling. At present, it has an annual production capacity of 500,000 tons of high-quality special steel and 460,000 tons of materials. On August 12, 2009, Guigang and Shougang were successfully combined and reorganized. On September 20, 2009, Shougang Guigang Company's new special material circular economy industrial base started construction. The new district is located in Zhazuo Town, Xiuwen County, about 50 kilometers away from Guiyang city center. Guizun Expressway and Sichuan-Guizhou Railway are adjacent to each other and the transportation is convenient. The construction of the new area has invested more than 10 billion yuan, and strives to build a high-quality special steel base with an annual output of 2 million tons of special and high-quality steel and a sales income of more than 10 billion yuan in 2012, becoming another circular economy, energy-saving, environmentally-friendly, clean and efficient type of Shougang Steel demonstration enterprises. After the completion of the new and special materials circular economy industrial base, the equipment is first-class, reaching the international advanced level and the domestic leading level; the products are mainly drill steel and drill tools, precision forgings, die flat steel, free-cutting steel, railway wheels, alloy steel Rod and wire, etc. The construction of the new area realizes the upgrading and transformation of the main steel business and enhances the market competition of special steel. The old district retreats from the second to the third, changes completely, develops and builds into a high-end residential area that integrates culture and commerce, implements a diversified system of property rights for diversified operations, and operates market-oriented operations. Eventually, a new scene of industrial interaction, mutual support, civilization and common prosperity between the old and new districts will be formed, and the scientific development of Guigang's historic leap will be realized.
