Here’s a detailed technical and logistical breakdown for the 2020 Vardanyan Street (Armenia) project involving iron (steel) light poles and high mast lights (8m/10m/12m/15m, 200 units total), covering design, compliance, and sourcing:
1. Project Overview
– Location: Vardanyan Street (likely an arterial road or urban area in Armenia).
– Scope: 200 steel poles (mix of standard light poles + high mast lighting).
– Heights:
– 8m–10m: Standard roadway/pedestrian lighting.
– 12m–15m: High mast lighting (e.g., intersections, public squares).
2. Pole Specifications
Material & Construction
– Material: Hot-dip galvanized steel (ASTM A123/A153 compliance for corrosion resistance).
– Alternative: Powder-coated steel for urban aesthetics.
– Construction:
– Seamless welded steel tubes (for structural integrity).
– Tapered or conical design (wind resistance).
– Flange/base plate thickness: 12–20mm (for high mast poles).
Wind & Load Ratings
– Wind speed: Designed for ≥28 m/s (100 km/h) (Armenian climate).
– Foundation: Reinforced concrete base (e.g., 1.2m–2m depth for 15m poles).
Surface Treatment
– Galvanization: Minimum 80µm zinc coating (for rust prevention).
– Optional: Additional polyester powder coating (RAL color codes).
3. Lighting & Electrical
– Luminaires:
– 8m–10m: LED street lights (e.g., 100W–150W, 10,000+ lumens).
– 12m–15m: High-power floodlights (e.g., 250W–400W LED, 30,000+ lumens).
– Smart Features (if applicable):
– Motion sensors.
– Remote monitoring (for energy efficiency).
4. Compliance & Standards
– International: ISO 9001, IEC 60598 (lighting safety).
– Local (Armenian):
– Armenian State Standard (GOST) for steel structures.
– Ministry of Urban Development approvals for public infrastructure.
5. Why Steel for This Project?
– Cost-Effectiveness: Cheaper than aluminum for tall/high-load poles.
– Durability: Galvanized steel withstands Armenia’s continental climate (cold winters, moderate winds).
– Local Preference: Steel poles were likely specified by Armenian contractors for public tenders.
6. Challenges & Solutions
– Corrosion Risk: Addressed via hot-dip galvanization.
– Installation Complexity: Taller poles (15m) require cranes + trained crews.
