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.
