Manufacturing

Our factory owns advances production lines and machines including bending calibration machine, hydraulic plate shears machine, shears machine, slitting machine, 208T hydraulic straightener, etc. All insure us to produce steel poles with best quality.

After the fabrication process as cutting plate, bending, forming, automatic welding, drilling holes, we get poles checked before galvanized, hot dip galvanized and powder coating and finally we get poles checked according to client& acute;s requirements.



?

Inspection
To ensure the quality, we have Microcomputer Automatic Carbon Sulfur Silicon Analyzer to check the raw material after?purchasing the steel sheet.

?

Then we have Physical Performance Test, Mechanical Test, Galvanization Thickness Test,?Load Test and Lad Test during and after the manufacturing process. All the effort is to meet our clients& acute; requirements.
