Inspection
To make sure the steel pole quality, we have professional technicians to inspect the poles before delivery. We have Lab Test, Workload Test, Steel thick Test, Galvanization thick Test, etc.
Production Process
Our factory owns advanced production lines and machines including bending calibration machine, hydraulic plate shears machine, shears machine, slitting machine, 208T hydraulic straightener, etc. All the purpose is to produce good quality steel poles.
The fabrication process as cutting plate, bending, forming, automatic welding, drill holes, quality checked before galvanized, hot dip galvanized and powder coating, finally quality checked according to client's requirement.
