Transmission Line Steel TowerTower structures used for transmission. Their structural characteristics are that various tower types belong toSpace TrussStructureRodPrimarily composed of a single pieceEqual angle steelOr combinedAngle ironComposition, materials generally usedQ235(A3F) andQ345（16MnTwo types are available. The connections between the rods are made with coarse bolts, which are subjected to shear force. The entire tower is composed of angle steel, connecting steel plates, and bolts. Some components, such as the tower base, are焊接 from several steel plates to form a composite part, therefore.Hot-Dip GalvanizedCorrosion-proof, transportation, and installation are extremely convenient. For iron towers with a height of 60 meters or less, a foot钉 is installed on one of the main materials of the tower to facilitate the climbing operations for construction personnel.
