Product Description
Wind power is one of the main varieties of steel carbon steel. The product is characterized by good welding performance, excellent mechanical properties, low temperature impact toughness (D, E), the current domestic wind tower steel grade used GB GB/T1591-2008 "low alloy structural steel" in Q345C, D, E and Z to the performance of steel, outside the subject mainly to European standard EN10025-2, EN10025-3 S235, S275/S355 and Z to the performance of steel series. This variety is widely used in wind towers, bridges, ships and important building structures. The wind power steel is in line with its original material standard and at the same time, it is in line with GB/T28410-2012 wind power construction steel standard. The steel for wind power generation has higher requirement for its surface quality.
