Hot dip galvanized Following ASTM A 123, color polyester power or any other standard by client required
Raw material test → Cuttingj →Molding or bending →Welidng (longitudinal )→Dimension verify →Flange welding →Hole drilling →Calibration → Deburr→Galvanization or powder coating ,painting →Recalibration →Thread →Packages
1) Enhances both electrical and mechanical performance
2) Well suited for terminal connections on high voltage side of a transformer 3) Accurate dimension and resistivity to adverse conditions
4) High tensile strength with optimum tolerance capacity
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.
Cuting the raw material that have meet all the standard required into different length and width.
Forming the cutted steel plate into the shape (circular or polygonal or other shape ) that as per specified in the drawing
After molding, weld the steel plate together. Usually it is longitudinal welds
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
Packing & Delivery
