ASTM A572Gr65 high strength steel plate is mainly used for the manufacture of transmission line steel pipe tower, communication pipe tower, road light pole, beautification tree and substation frame, etc. ASTM A572Gr65 high strength steel plate have the follow characteristics: 1. low carbon low silic 2.high strength, high toughness . Adhesion of galvanized zinc layer was enhanced through the control the trace element. ASTM A572Gr65 high strength steel plate won't turn to black if used for a long time. The quality of hot dip galvanizing is guaranteed, and various surface special processing can be carried out, such as: hot galvanizing anode oxidation, environmental spraying etcA572Gr65 high strength steel plate is mainly composed of carbon elements and other minor alloying elements.More detailed information, please refer to the flowing table:
