Welding |
We have passed flaw testing. Internal and external double welding makes the welding beautiful in shape. Welding Standard: AWS (American Welding Society) D 1.1 |
Galvanization | Hot dip galvanization with thickness of 80-100µm average in accordance with Chinese standard GB/T 13912-2002 or American standard ASTM A123, ISO: 2626-1985 |
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. |
