    Minimum yield strength: 355 mpa for power pole
    Minimum ultimate tensile strength: 490 mpa for power pole
    Max ultimate tensile strength: 620 mpa for power pole
    Standard: ISO 9001 for power pole
    Length of per section: Within 14m once forming without slip joint
    Welding: We has past flaw testing.Internal and external double welding makes the welding beautiful in shape
    Welding Standard: AWS ( American Welding Society ) D 1.1
    Thickness: 1mm to 30 mm
    Production Process
    Raw material test → Cutting →Molding or bending →Welding (longitudinal )→Dimension verify →Flange welding →Hole drilling →Calibration →Deburr→Galvanization or powder coating ,painting →Calibration →Thread →Packages
    Our poles as normal cover by Mat or straw bale at the top and bottom ,anyway also can following by client required , each 40HC or OT can loading how many pcs will calculation base on the client actually specification and data.China Power Transmission Poles manufacturers
