| Thickness | 1 mm to 30 mm |
| Production Process | Raw material test → Cutting → Molding or bending → Welding (longitudinal) → Dimension verify → Flange welding → Hole drilling → Calibration → Deburr → Galvanization or powder coating, painting → Recalibration → Thread → Packages |
| Packages | Our poles are normally covered by Mat or straw bale at the top and bottom, but can also follow client requirements. Each 40HC or OT loading capacity will be calculated based on the client's actual specifications and data. |
Established in 1991, Jiangsu Milky Way Steel Poles is located in Wuxi, East of China, near one of the largest sea ports of China, Shanghai Port. Our products have been widely used in power transmission, signal transmission and lighting for street, road, square, palaestra, and more.
