The stud bolts that produced by Anyang Longteng have high performance, high tensile strength. Impact energy of grade 12.9 bolts at -40℃ can be 27J, which means quite good performance in low temperature. So that the studs can be used in cold weather oil platform. Highest tensile strength that Anyang Longteng Group can produce, is grade 12.9. The bolts provide steel structures and machineries high property to bend, strength, pre-stress, post-tension. So that the studs are widely applicated in wind turbine foundation, wind turbine blade,  shipbuilding, bridge, big machineries. roof supporting, etc.
