The 12-sided tapered steel high mast pole is a high-strength support structure engineered for large-area outdoor lighting. Fabricated from high-quality steel plates via rolling, automatic welding, and hot-dip galvanizing, it features superior wind resistance, high corrosion protection, stable structure, and easy maintenance. Widely used in airports, ports, stadiums, highways, large squares, and logistics parks to deliver efficient, uniform, wide-range lighting coverage.
Applications:
Certified Quality for Global Projects
12-Sided Tapered Steel High Mast Pole | Durable Galvanized High Mast Lighting Poles Factory
12-Sided Tapered Structure, Excellent Mechanical Performance
Dodecagonal tapered design ensures even stress distribution, with higher torsion/bending resistance than round/octagonal poles. Segmented plug-in structure for easy installation and low transportation cost.
High-Strength Steel, Safe & Durable
Made of high-strength low-alloy steel (Q235B/Q355B/ASTM A572 Gr.50/S355JR), yield strength ≥345MPa, wind resistance up to 60m/s, seismic grade 8.
Hot-Dip Galvanized for Long Life
Internal & external hot-dip galvanizing (zinc layer 85–120μm), compliant with GB/T 13912, ASTM A123, EN ISO 1461. 30-year rust-proof protection, adaptable to coastal, acid rain, and high-humidity environments.
Precision Welding, Reliable Quality
Fully automatic submerged arc/CO₂ welding, smooth welds with no defects. 100% ultrasonic testing, compliant with AWS D1.1, EN 15614 standards, 100% structural strength qualified.
Smart Lifting System (Optional)
Built-in electric/manual dual-control lifting device, speed 3–5m/min, with electromagnetic brake, anti-fall protection, manual operation during power failure. No high-altitude maintenance required.
Custom Design for All Scenarios
Height 15–40m optional, wall thickness 3–16mm, flange/direct burial installation. Equipped with lightning rod, intelligent control, multi-cantilever lamp panel to meet various engineering needs.
