Galvanization-The Manufacturing of Steel Tubular Poles
Describe:
The completed steel monopole, steel tube pole, and steel tubular tower are hot-dip galvanized at a bath temperature of approximately 445–465°C for 2–5 minutes. Coating thickness conforms to ISO 1461 or GB/T 13912. Coating quality is verified by copper sulfate immersion tests and adhesion (hammering) tests. The galvanized surface is smooth and free of uncoated areas, providing over 20 years of corrosion resistance in outdoor environments.
