We have 15sets full-automatic lines of rolling&forging productive lines, the technology is supported by Beijing Science and 

Technology University. The annual production output is 200,000Ton. The diameter is from 20mm-200mm. The meterial of the products

is high quality special steel bars, the characteristic of the products are high hardness, well abrasive resisitance,non-deformation,

non-cracking and low breakage.
