-
The poles are manufactured from high-quality structural steel and formed into a tapered, multi-section (multi-row) conical shape to ensure excellent mechanical strength and stability. Each pole section is precisely fabricated through automated bending and welding processes to achieve consistent dimensions and superior structural integrity.
-
After fabrication, all pole surfaces undergo a full hot-dip galvanization process in accordance with international corrosion-protection standards. This zinc coating provides long-term resistance against rust, weathering, and harsh environmental conditions, ensuring a durable, maintenance-free service life in outdoor electrical and utility applications.
