Self-Supporting Polygonal Galvanized Electric Steel Pole are widely used in electrical power transmission and distribution industry. In order to meet the increasingly higher demand for steel poles, our company design and produce many kinds of steel poles for the power transmission and distribution system. Besides, our electrical steel poles have been tested and approved by the Transmission Pole Tower Testing Station.

But to design the practical poles for customers use, normally we need customer to provide us some parameter, like as following :

-  Pole top design load

-  Where is the position of the load , the distance from the top 

-  The wind Speed

-  How will the wire distribute

-  Pole type with Burial Type or Base Plate type

-  The connections mode , use slip joint or flange

-  and others we can further more discuss when we need

Production Process

•Raw material test



•Welding (longitudinal )

•Dimension verify

•Flange welding

•Hole drilling



•Galvanization or powder coating or Bituminous painting



Our steel poles, being manufactured from steel sheet that has been subjected to hydraulic pression and longitudinal welding, has a tapered tubular structure with a multilateral cross section. To achieve a proper height, steel poles can be assembled by insert mode or flange mode at the installation site.

To assure our products qualified , we take steps as follows :

1. Management team : We have employed the experienced senior experts to take charge of the whole management ,especially the technical management and quality management.

2. Introducing ISO management: We are aware of ISO 9001:2008 certificate.

3. QC Inspection :It is our company policy that all the finished products should be inspected by our specialized QC in every manufacture step and before each shipment

4. Design and Detail

Lofting and designing software :We have transmission power pole designing software which can help us design all kinds of steel poles ,at the same time ,the TMA and LMA are adopted by us to design the drawing accurately
