3. Height: according to design
4. Tower Type: suspension tower, angle tower, tension tower, terminal tower.
5. Material: GB Q235, Q345, Q420
ASTM A36, A52
or other equivalent standards
6. Fabrication Process: Raw material test → Cutting Dimension verify →Hole drilling →sample assemble → surface clean→ Galvanization or powder coating ,painting →Recalibration →PGalvanizing process of overhead transmission tower
7. Process of Galvanization:
1. Degreasing of tower parts with Sodium Hydroxide solution.
2. Pickling to clean up the surface with HCl solution
3. Rinsing twice with fresh water to remove the acid content.
4. Fluxing wth synth flux to prepare surface for galvanizing.
5. Drying on hot plate.
6. Dipping in zinc bath with 99.95% pure zinc at 450° C to 465° C temperature.
7. Quenching in water.
8. Dichromating.
Thickness< 5mm, galvanization thickness≥ 460G/M² (65um)
Thickness> 5mm, galvanization thickness≥ 610G/M² (86um)
All our galvanizing zinc thickness is strictly tested before delivery in view of its
