With the rapid development of China's steel strand industry, with the double push of the supply side reform and the construction of the Belt along the way, the capacity structure has been optimized, the quality of products has been greatly improved, and a large number of high-quality products have gone abroad. The demand performance exceeds expectations, and the pattern of market supply exceeding demand has changed. The author analyzes and forecasts the market situation of steel strand from the following aspects.
The steel strand is a steel product composed of several steel wires. According to the needs, zinc coating, zinc aluminum alloy coating, aluminum coating, copper coating and epoxy resin coating can be added on the surface of carbon steel. Steel strand can be divided into: prestressed, unbonded, galvanized steel strand, etc. This paper only introduces the prestressed steel strand with the largest market circulation and consumption.
Prestressed steel strand is a stranded steel cable composed of 2, 3, 7 or 19 high-strength steel wires, which has been stress relieved (stabilized). The main features are high strength and good relaxation performance. In addition, it is relatively straight when it is unfolded and suitable for prestressed concrete or similar purposes. It is widely used in infrastructure projects such as high-speed railway construction, expressway and national and provincial highway bridge. China's prestressed steel strand industry originated in the 1960s, began to introduce western technology in 1988, and began to develop rapidly after 1995, mainly due to the sustained growth of China's economy and the country's policy of continuous investment in infrastructure. Now China has become the largest prestressed steel strand consumer market in the world.
At present, the production bases of steel strand are mainly in Tianjin, Jiangsu, Hebei and Henan, which account for 70% of the total output of the country. Tianjin has obvious location advantages, and the logistics in the center of the North-South channel is more convenient, which can easily radiate Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia and northeast provinces. Due to the development of Tianjin strand industry cluster, B steel production of iron and steel enterprises in the region is driven, and Rongcheng steel and Aosen steel provide sufficient raw material supply in the region. Manufacturers along the Yangtze River mainly radiate to Jiangsu, Zhejiang, Shanghai, Fujian and Guangdong, benefiting from the developed inland water network transportation and low freight. There are Shagang, Yonggang, and other manufacturers in the area as raw material suppliers with sufficient supply.
Thanks to the continuous growth of China's economy and the state's policies on infrastructure investment, China's prestressed steel strand industry has become a super giant in the global industry, far larger than the total scale of European and American enterprises. The increase in infrastructure investment such as bridges, railways and expressways has provided a strong support for the prestressed steel strand market, and the industry is booming. With the implementation of the "The Belt and Road" construction, the domestic and foreign investment boom in infrastructure will bring more room for the development of prestressed steel strand market.
