treated anchor steel bar is a high performance steel that is inductively heat
treated from hot rolled steel bars. It is widely used in anchoring, supporting,
reinforcement and other projects in coal mine roadways, highway slopes,
tunnels, dams, urban foundation pits etc. Pre-stressed concrete works,
especially in coal mines.
This product not only has
higher strength grade than ordinary hot rolled products, but also effectively

China's small and medium-sized foundry mold enterprises have achieved remarkable results in terms of profits and taxes, increased employment, absorption of labor, and contribution to the economy.
Rapid development of domestic mold SMEs
With the development of small and medium-sized private enterprises in China, the contribution of small and medium-sized enterprises to society has become increasingly prominent. In terms of profits and taxes, the taxes paid by SMEs nationwide have become the backbone of local finance. China's foundry mold enterprises are also an important member of these SMEs and have contributed a lot of profits and taxes to our country. In terms of the number of employed people, small and medium-sized foundry mold companies have obvious advantages over large companies in job creation because of their low investment, flexible operation, low cost, and low skill requirements for workers. Small-scale foundry mold companies only need tens of thousands of yuan to buy one device and three or four people can produce it. These small enterprises have small scale, high efficiency and considerable economic benefits, and have made outstanding contributions to China's economic construction.
