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.
