Production Process

As an BV ,ISO ,SGS approved supplier in China ,we have more than 20 years produce and export steel pole ,and we can assure the pole we offered is of sound quality which made from qualified material with our professional workers and advance equipment .

 

Raw Material

When purchasing the raw material (steel plate), on sheet of mill certificate from mill factory must be enclosed. When the raw material arrives at the warehouse, the quality department must take the elongation test and the chemical composition analysis to make sure the raw material have meet all the standard that the needed before production.

 

Material Test and Sample

1. All of our material are purchased from famous mill factory to assure the quality


2. A mill certificate issued by the mill factory with stamp and signature must be provided before unload the material in our factory ,otherwise we have our reason to refuse the material .


3. Before put into production ,all the material must pass the chemical and physical analysis to make sure that they have meet the requested strength and component.

Plasma Cutting

 

Cutting the raw material that have meet all the standard required into different length and width. CNC laser cutting is used to direct the material or the laser beam generated. A typical commercial laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.

 

Molding

Forming the cut steel plate into the shape (circular or polygonal or other shape ) that as per specified in the drawing. This invention relates to forming devices and more particularly to devices or machines for bending longitudinally rolled sections or strips of metal stock to desired curvilinear shapes.

Welding

After molding, weld the steel plate together. Usually it is longitudinal welds. It adopts A.C.inverter control, with functions of stable running and fast traveling speed; The seam-tracking arc-guide mechanism is three-spindle system to guarantee the alignment without aberrancy; The main frame and welding machine are intergrated control, with flux auto-recovering system and it is easy to operate with high efficiency.

Galvanization

All poles internally and externally are to be hot-dip galvanized in accordance with requirement mentioned in the relevant drawing or specification
Galvanization standard:IS2629-1985 ,BS729-1971

In every production procedure ,we have our inspector around to check whether it was done according with the drawing .
