Product Specification

Galvanized Tube Steel Steel Transmission Pole Galvanized Steel Pole

Product Description:

Manufacturing:

Raw material: Q235 or Q345 in China. We get the raw material checked in our lab test room. Silicon less than2%. We have carbon and sulfur analyzer to check the elements of the steel sheet. We'll return the steel if they are unqualified. So in this way, we can control the quality of the steel poles from the first beginning.

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 insure us to produce steel poles with the best quality.

Process:

1. Raw materialtest :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.

2. Cuting :Cuting the raw material that have meet all the standard required into different length and width .

3. Molding :Forming the cutted steel plate into the shape (circular or polygonal)that as per specified in the drawing. 

4. W elding :After molding ,weld the steel plate together .Uauslly it is longitudinal welds.

5. Dimension verify :Afer welding ,check the diameter ,length according to the drawing .

6. Flange:Weld the flange into the main pole

Welding standard:ASTM A 252-1998 or ASTM A 714-1999

7. Drill:Drill the hole at the right location as requested in the drawing.

8. Calibration:check the straightness and diameter to make sure it meet all the requirement .

9. Deburr: All burrs after drilling or cutting of steels shall be deburred and appropriately chamfered before galvanized

10. 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

11. Recalibration:recheck the straightness and diameter to make sure it meet all the requirement after galvanization.

12. Thread:Thread the parts that needs screw thread ot make sure it can installed successfully at site .

13.Packages: Our poles as normal cover by sea /road -worthy wooden packing material ,anyway also can following by client required , each 40HC or OT can loading how many pcs will calculation base on the client actually specification and data

Product Specification:

The manufactured items will be inspected at the manufacturer’s plant by the Engineering Team appointed by the purchaser. Tests shall be performed in accordance with the relevant standards unless otherwise stated.

Before ffull-scalemanufacture is commenced, 3 (three) samples of each type of pole shall be prepared for testing and approval by the engineer. Production items not meeting the same standard as the initial samples approved by the Engineering Team will be rejected.

We have Lab Test, Workload Test, Steel thickness Test, Galvanization thickness Test, etc.
