Description:
The material we use is from Baosteel.According to the different
strength request,we can use the Q235,Q345 and GR65.The strength of
GR 65 is best and Q235 is lowest.
For the street light pole,we usually choose Q235 and Q345.
The good quality of steel material guarantee the good quality of
the finished steel pole.
Production Flow:
The production process:Row material test → Cutting →Molding or
bending →Welding (longitudinal )→Dimension verify →Flange
welding→Hole drilling →Calibration → Deburr→Galvanization or powder
coating ,painting →Recalibration →Thread →Packages
